Nigerian startup Rensource Energy has raised a $20 million Series A round co-led by CRE Venture Capital and the Omidyar network.
The renewable energy company builds and operates solar-powered micro-utilities that provide electricity to commercial community structures, such as open-air trading bazaars.
Launched in 2016, the startup has shifted its operating strategy. “We’ve pivoted away from a residential focus…and we’re building much larger systems to become essentially the utility for these large urban markets we have a lot of in Nigeria,” Rensource co-founder Ademola Adesina told TechCrunch.
The company has a partnership with German manufacturer BOS AG, with whom it designs specialized panels for it use case. Rensource also has developer teams in Nigeria and Europe for its software-related programs.
In addition to becoming a micro-energy provider to Nigeria’s robust SME classes, the startup aims to offer them B2B services. With the $20 million round, Rensource is launching its Spaces Offline to Online platform for supply-chain services, including business-analytics and working capital options.
“It’s a mini-ERP tool. We’re trying to bring a universe of people who are banked, but…still offline — their products are offline, they don’t track anything, and there’s no data behind their business — online,” said Adesina.

The benefit Rensource seeks to deliver to Nigeria’s SMEs — at a profit for itself — is to lower overhead costs through better business practices and free them from the bane of generators.
Across marketplaces in West Africa, noisy, fuel-guzzling and pollution-producing generators are like an unwelcome, yet necessary business partner.
Lack of affordable and reliable electricity in Nigeria creates a massive real and opportunity cost to Africa’s largest economy.
For perspective, the West African country is roughly the size of Texas, with a 200 million population larger than Russia, and generates less gigawatt hours of electricity annually than the U.S. state of Connecticut.
Nigerian businesses (and citizens) adjust for these power deficiencies by spending on diesel fuel and generators.
The IMF’s 2019 Nigeria report quoted economic losses of $29 billion in Nigeria due to unreliable electricity supply. On global Doing Business rankings, Nigeria ranked 169 out of 190 countries in the category of “Getting Electricity.”
This difficulty and cost weighs particularly heavy on Nigeria (and the continent’s) SMEs, which often operate in Africa’s informal economy — projected to be one of the largest off-the grid commercial spaces in the world.
Rensource’s micro-utility model deploys power clusters — made up of solar-panels, batteries and a power management system — adjacent to markets and commercial hubs. The energy application isn’t totally clean, as the startup still uses its own diesel backup system.
Rensourse has used this model to become an off-grid energy provider in six states in Nigeria, and powers the Sabon Gari market — one of the country’s largest, located in northern Kano State.
The company plans to expand to 100 markets within Nigeria and to additional African countries within 24 months, according to Adesina.
Rensource generates revenue from charging merchants daily, weekly or monthly fees. “In 2017, we did a few hundred thousand dollars in revenue. Last year we did about $7 million in revenue, and this year we’ll do better than that,” Adesina said.
The company doesn’t release official financials, but generated a small profit last year, according to Adesina. He named deploying more of its micro-utilities to new markets and diversifying services as the path to long-term profitability.
Rensource differentiates itself from many home-kit solar energy startups in Africa, such as M-Kopa, by becoming a renewable energy utility at scale.
The startup’s CEO sees the model as a classic leapfrog tech business, effectively bypassing Nigeria’s deficient electricity grid and providing a less capital intensive alternative to large (and often complicated) energy infrastructure projects.
Rensource is also following a trend by some Nigeria-based startups, such as trucking-logistics company Kobo360 and motorcycle ride-hail company Gokada, to shape a suite of additional services around the needs of core clients.
In Rensource’s case, those clients are SMEs and traders in the informal economy. “This informality of theirs is what we see as an opportunity in building this new business line and bringing these [merchants] into the online world,” said Adesina.

Meatable, the Dutch startup developing cruelty-free technologies for manufacturing cultured meat, is pivoting to pork production as a swine flu epidemic ravages one quarter of the world’s pork supply — and has raised $10 million in financing to support its new direction.
When the company unveiled its technology last year, it was one of several companies working on the production of meat derived from animal cells — a method of meat production that theoretically has a far smaller carbon emissions footprint and is better for the environment than traditional animal farming.
At the time, it was one of several companies — including Memphis Meats, Future Meat Technologies, Aleph Farms, HigherSteaks and many, many pursuing technologies — to bring cultured beef to market. Now, as pork prices rise globally, Meatable becomes one of the first companies to publicly shift gears and turn its attention to the other white meat.

That’s not the only way the company is setting itself apart from its peers in the market. Meatable is also an early claimant to a commercially viable, patented process for manufacturing meat cells without the need to kill an animal as a prerequisite for cell differentiation and growth.
Other companies have relied on fetal bovine serum or Chinese hamster ovaries to stimulate cell division and production, but Meatable says it has developed a process where it can sample tissue from an animal, revert that tissue to a pluripotent stem cell, then culture that cell sample into muscle and fat to produce the pork products that palates around the world crave.
“We know which DNA sequence is responsible for moving an early-stage cell to a muscle cell,” says Meatable chief executive Krijn De Nood.
To pursue its new path, the company has raised $7 million from a slew of angel and institutional investors and a $3 million grant from the European Commission . Angel investors include Taavet Hinrikus, the chief executive and co-founder of TransferWise, and Albert Wenger, a managing partner at the New York-based venture firm Union Square Ventures.
Meatable’s De Nood says that the new cash will be used to accelerate the development of its prototype. The small-scale bioreactor the company had initially targeted for development in 2021 will now be ready by 2020 and the company is hoping to have an industry-scale plant online manufacturing thousands of kilograms of meat by 2025, according to De Nood.
Industrial farming is responsible for between 14% and 18% of the greenhouse gas emissions linked to global climate change and Meatable argues that cultured (lab-grown) meat has the potential to use 96% less water and 99% less land than industrial farming. Powering facilities using renewable energy could further reduce emissions associated with meat production, according to Meatable.

Google announced today that it was investing €3 billion (approximately US$3.3 billion) to expand its data center presence in Europe. What’s more, the company pledged the data centers would be environmentally friendly.
This new investment is in addition to the $7 billion the company has invested since 2007 in the EU, but today’s announcement was focused on Google’s commitment to building data centers running on clean energy as much as the data centers themselves.
In a blog post announcing the new investment, CEO Sundar Pichai made it clear that the company was focusing on running these data centers on carbon-free fuels, pointing out that he was in Finland today to discuss with prime minister Antti Rinne building sustainable economic development in conjunction with a carbon-free future.
Of the €3 billion the company plans to spend, it will invest €600 million to expand its presence in Hamina, Finland, which he wrote “serves as a model of sustainability and energy efficiency for all of our data centers.” Further, the company already announced 18 new renewable energy deals earlier this week, which encompass a total of 1,600-megawatts in the U.S., South America and Europe.
In the blog post, Pichai outlined how the new data center projects in Europe would include some of these previously announced projects:
Today I’m announcing that nearly half of the megawatts produced will be here in Europe, through the launch of 10 renewable energy projects. These agreements will spur the construction of more than 1 billion euros in new energy infrastructure in the EU, ranging from a new offshore wind project in Belgium, to five solar energy projects in Denmark, and two wind energy projects in Sweden. In Finland, we are committing to two new wind energy projects that will more than double our renewable energy capacity in the country, and ensure we continue to match almost all of the electricity consumption at our Finnish data center with local carbon-free sources, even as we grow our operations.
The company is also helping by investing in new skills training, so people can have the tools to be able to handle the new types of jobs these data centers and other high-tech jobs will require. The company claims it has previously trained 5 million people in Europe for free in crucial digital skills, and recently opened a Google skills hub in Helsinki.
It’s obviously not a coincidence that the company is making an announcement related to clean energy on Global Climate Strike Day, a day when people from around the world are walking out of schools and off their jobs to encourage world leaders and businesses to take action on the climate crisis. Google is attempting to answer the call with these announcements.

Google today announced its largest package of renewable energy deals yet. Worth a total of 1,600-megawatts, the package includes 18 deals in the U.S., Chile and Europe. This brings Google’s current set of wind and solar agreements to about 5,500 megawatts (MW) and the company’s number of total renewables projects it’s involved in to 52. Google argues that these new projects it announced today will drive about $2 billion in investments in new energy infrastructure.
In the U.S., Google says it’ll purchase a total of 720 MW from solar farms in North Carolina, South Carolina and Texas. In Chile, it’s buying an additional 125 MW to power its data center there. For reasons only known to Google PR, the company will only announce details of its plans for Europe tomorrow, at an event in Finland, where Google CEO Sundar Pichai will be present.
In today’s announcement, Pichai notes that many of Google’s earlier investments were in wind energy. Its new investments in the U.S. are mostly in solar, though. The reason for that, he notes, is the declining cost of solar. In Chile, the company is investing in a hybrid solar and wind deal for the first time. “Because the wind often blows at different times than the sun shines, pairing them will allow us to match our Chilean data center with carbon-free electricity for a larger portion of each day,” Pichai writes.
Google’s announcements follow Amazon’s pledge to run its business on 100% renewable energy by 2030 and buy 100,000 electric vans.

In Washington today, Amazon announced a series of initiatives and issued a call for companies to reduce their carbon emissions 10 years ahead of the goals set forth in the Paris Agreement as part of a sweeping effort to reduce its own environmental footprint.
“We’re done being in the middle of the herd on this issue—we’ve decided to use our size and scale to make a difference,” said Jeff Bezos, Amazon founder and chief executive, in a statement. “If a company with as much physical infrastructure as Amazon—which delivers more than 10 billion items a year—can meet the Paris Agreement 10 years early, then any company can.”
Bezos’ statement comes as employees at his own company and others across the tech industry plan for a walkout on Friday to protest inaction on climate change from their employers.
Amazon’s initiatives include an order for 100,000 delivery vehicles from Rivian, a company in which Amazon has previously invested $440 million.
Electric vans will appear on roads by 2021 and Amazon expects to have 10,000 of the new electric vehicles on the road by 2022 and 100,000 by 2030. The fleet is expected to reduce carbon emissions by 4 million metric tons per year by 2030, the company said.
In addition, Amazon said it would commit another $100 million to reforestation projects through the Right Now Climate Fund in partnership with The Nature Conservancy. That fund will invest in the protection of forests, wetlands and peatlands that now serve as carbon sinks, which remove millions of metric tons of carbon from the atmosphere.
Finally, the company said it will speed up its adoption of renewable energy with the goal of converting 80% of the company’s energy sources to renewable energy by 2024, with the goal of reaching 100% renewable energy use by 2030.
Amazon has already initiated 15 utility-scale wind and solar renewable energy projects that will generate 1.3 gigawatts of renewable capacity and deliver some 3.8 million megawatt hours of clean energy, according to the company.
All of these efforts will be backstopped by a new sustainability reporting initiative, which will be housed on a new website monitoring and tracking the company’s progress toward its sustainability goals, the company said.
These steps are part of a push from Amazon to get other companies to sign on to a global non-binding agreement to accelerate the adoption of renewable energy and the reduction of carbon emissions.
Companies that sign on to the Amazon-inspired “Climate Pledge” agree to measure and report greenhouse gas emissions regularly; implement decarbonization strategies on a timeline that matches the Paris Agreement; and neutralize remaining emissions with quantifiable and permanent offsets to achieve net zero annual carbon emissions by 2040.
“I’ve been talking with other CEOs of global companies, and I’m finding a lot of interest in joining the pledge. Large companies signing The Climate Pledge will send an important signal to the market that it’s time to invest in the products and services the signatories will need to meet their commitments,” Bezos said in a statement.
The initiative is backed by international political luminaries like Christiana Figueres, the former climate change chief and founding partner of Amazon’s collaborator on The Climate Pledge, Global Optimism.
“Bold steps by big companies will make a huge difference in the development of new technologies and industries to support a low carbon economy,” said Figueres, in a statement. “With this step, Amazon also helps many other companies to accelerate their own decarbonization. If Amazon can set ambitious goals like this and make significant changes at their scale, we think many more companies should be able to do the same and will accept the challenge. We are excited to have others join.”

Arch Rao, the former head of product at Tesla who was behind the company’s Powerwall home energy storage is system, is back with a new company pitching energy management and efficiency for homes.
Span is looking to upgrade the electrical fuse box for homes with a digital system that integrates into the existing circuit breaker technology that has been the basis for home energy management for at least a century.
Rao and his team are looking to make integrating renewable power, energy storage and electric vehicles easier for homeowners by redesigning the electrical panel for modern energy needs.
“We packaged the metering controls and compute between the bus bar and the breaker,” says Rao. “Energy flows through the panel through a breaker bar and the breaker bar has tabs that you slot your breakers into… that tab is usually a conductor. We have designed a digital sub-assembly that packages current metering, voltage measurement and the ability to turn each circuit on or off.”
The technology is meant to be sold through channels like solar energy installers or battery installers. The company already has plans to integrate its power management devices with energy storage systems like the ones available from LG .
Initially, Span expects to be selling its products in states like California and Hawaii where demand for solar installations is strong and homeowners have significant benefits available to them for installing renewable energy and energy efficiency systems.
For homeowners, the new power management system means that they have control over which parts of the home would be powered in the event of an outage. The company’s technology connects the entire home to a renewable system. Using existing technologies, installers have to set up a separate breaker and rewire certain areas of the home to receive the power generated by a renewable energy system, Rao says.
That control is handled through a consumer app available to download on mobile devices.
Span is backed by a slew of early investors, including Wireframe Ventures, Wells Fargo Strategic Capital, Ulu Ventures, Hardware Club, Energy Foundry, Congruent Ventures and 1/0 Capital, and intends to raise fresh cash before the end of the year. Rao said the round would be “in the low double digits” of millions.

Walmart came out swinging earlier this week in a lawsuit that accused Tesla of breach of contract and gross negligence over problems with rooftop solar panel systems installed at the retail giant’s stores.
Now, just days later, the lawsuit has been placed on hold while the two companies try to reach an agreement that would keep the solar installations in place and put them back in service, according to a joint statement issued late Thursday night.
“Walmart and Tesla look forward to addressing all issues and re-energizing Tesla solar installations at Walmart stores, once all parties are certain that all concerns have been addressed,” the statement read. “Together, we look forward to pursuing our mutual goal of a sustainable energy future. Above all else, both companies want each and every system to operate reliably, efficiently, and safely.”
Walmart hasn’t dropped the lawsuit. The complaint is still on file with New York state court. But the two parties are going to try to reach an agreement that would avoid a lawsuit.
The lawsuit, which is aimed at Tesla’s energy unit that was formerly known as SolarCity, alleges that seven fires on Walmart rooftops were caused by the solar panel systems. Walmart asked Tesla to remove the solar panel systems on all 244 stores where they are currently installed and to pay for damages related to fires that the retailer alleges stem from the panels.
Now, a Walmart spokesperson said it is “actively working towards a resolution” with Tesla.
Neither Tesla or Walmart would explain the details of the negotiations.
The stakes are high for Tesla. Earlier this month, Tesla CEO Elon Musk announced a new rental offering for solar power in a bid to reboot the flagging renewable energy business.
Tesla’s share of the solar market has declined since its merger with SolarCity in 2016. In the second quarter Tesla deployed only 29 megawatts of new solar installations, while the number one and two providers of consumer solar, SunRun and Vivint Solar, installed 103 megawatts and 56 megawatts, respectively.
Tesla’s renewable energy business includes residential and commercial solar and energy storage products. The company also has a utility-scale energy product called Megapack. While Tesla still produces solar panels for residential use, much of its focus has been on developing its solar roof, which is comprised of tiles. It still operates a commercial business, which targets municipalities, schools, affordable housing, enterprise and agriculture and water districts as customers.
The company doesn’t provide a breakdown of its solar installations, making it difficult to determine if the commercial business is flat, falling or on the rise. Language in its latest 10-Q suggests Tesla is putting a renewed effort into its solar business.
Tesla said it’s working on revamping the customer service experience for solar products, according to the 10-Q. The company said while its retrofit solar system deployments have decreased it expects they “will stabilize and grow in the second half of the year.”

Imagine a moving tower made of huge cement bricks weighing 35 metric tons. The movement of these massive blocks is powered by wind or solar power plants and is a way to store the energy those plants generate. Software controls the movement of the blocks automatically, responding to changes in power availability across an electric grid to charge and discharge the power that’s being generated.
The development of this technology is the culmination of years of work at Idealab, the Pasadena, Calif.-based startup incubator, and Energy Vault, the company it spun out to commercialize the technology, has just raised $110 million from SoftBank Vision Fund to take its next steps in the world.
Energy storage remains one of the largest obstacles to the large-scale rollout of renewable energy technologies on utility grids, but utilities, development agencies and private companies are investing billions to bring new energy storage capabilities to market as the technology to store energy improves.
The investment in Energy Vault is just one indicator of the massive market that investors see coming as power companies spend billions on renewables and storage. As The Wall Street Journal reported over the weekend, ScottishPower, the U.K.-based utility, is committing to spending $7.2 billion on renewable energy, grid upgrades and storage technologies between 2018 and 2022.
Meanwhile, out in the wilds of Utah, the American subsidiary of Japan’s Mitsubishi Hitachi Power Systems is working on a joint venture that would create the world’s largest clean energy storage facility. That 1 gigawatt storage would go a long way toward providing renewable power to the Western U.S. power grid and is going to be based on compressed air energy storage, large flow batteries, solid oxide fuel cells and renewable hydrogen storage.
“For 20 years, we’ve been reducing carbon emissions of the U.S. power grid using natural gas in combination with renewable power to replace retiring coal-fired power generation. In California and other states in the western United States, which will soon have retired all of their coal-fired power generation, we need the next step in decarbonization. Mixing natural gas and storage, and eventually using 100% renewable storage, is that next step,” said Paul Browning, president and CEO of MHPS Americas.
Energy Vault’s technology could also be used in these kinds of remote locations, according to chief executive Robert Piconi.
Energy Vault’s storage technology certainly isn’t going to be ubiquitous in highly populated areas, but the company’s towers of blocks can work well in remote locations and have a lower cost than chemical storage options, Piconi said.
“What you’re seeing there on some of the battery side is the need in the market for a mobile solution that isn’t tied to topography,” Piconi said. “We obviously aren’t putting these systems in urban areas or the middle of cities.”
For areas that need larger-scale storage that’s a bit more flexible there are storage solutions like Tesla’s new Megapack.
The Megapack comes fully assembled — including battery modules, bi-directional inverters, a thermal management system, an AC breaker and controls — and can store up to 3 megawatt-hours of energy with a 1.5 megawatt inverter capacity.
The Energy Vault storage system is made for much, much larger storage capacity. Each tower can store between 20 and 80 megawatt hours at a cost of 6 cents per kilowatt hour (on a levelized cost basis), according to Piconi.
The first facility that Energy Vault is developing is a 35 megawatt-hour system in Northern Italy, and there are other undisclosed contracts with an undisclosed number of customers on four continents, according to the company.
One place where Piconi sees particular applicability for Energy Vault’s technology is around desalination plants in places like sub-Saharan Africa or desert areas.
Backing Energy Vault’s new storage technology are a clutch of investors, including Neotribe Ventures, Cemex Ventures, Idealab and SoftBank.

Apple led the way in solar usage as technology companies step up their development of renewable energy projects to offset their carbon emissions.
That’s the word from the Solar Energy Industry Association in its latest tally of leading corporate solar energy installers across the U.S.
Last year, Apple installed 400 megawatts of solar capacity to lead all companies in the U.S.
“Top companies are increasingly investing in clean, reliable solar energy because it makes economic sense,” said Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association (SEIA), in a statement. “[And] corporate solar investments will become even more significant as businesses use solar to fight climate change, create jobs and boost local economies.”

Four of the top 10 corporate solar users in the U.S. were tech companies. Amazon was No. 2 on the Solar Energy Industry Association’s list of companies tapping solar energy to power their businesses. The data center company Switch and search giant Google (a subsidiary of Alphabet) came in as the fifth and sixth companies.
“Playing a significant role in helping to reduce the sources of human-induced climate change is an important commitment for Amazon,” said Kara Hurst, director of Sustainability, Amazon, in a statement. “Major investments in renewable energy are a critical step toward addressing our carbon footprint globally. We will continue to invest in these projects and look forward to additional investments this year and beyond.”
The price for solar continues to come down, which is increasing the adoption — and scale — of solar installations in the U.S.

According to the SEIA, the biggest jump in solar installations have happened in the last three years. In all, 7 gigawatts of solar capacity has been installed at commercial locations, which is enough to power 1.4 million homes.
Of course, these numbers still need to increase even more dramatically for the corporate world to show that it’s serious about addressing climate change. While it’s important to acknowledge the successes of companies that are taking strides to incorporate more renewable energy into their operations, the goal for these massive industrial and technology giants (and really the goal for every institution) should be to get to as close to full decarbonization as possible.
The world has 10 years to wean itself off its current emissions-heavy consumption habits. Increasing solar usage is a step in the right direction, but it’s only a step.

When Landon Brand and Benjamin Stanfield graduated from the University of Southern California this year, they already had the plans for Project Wren, their service for selling carbon offsets to a new generation of conscious consumers.
Along with fellow co-founder Mimi Tran Zambetti (who’s still attending USC), Brand and Stanfield aim to make carbon offsets more accessible to people who may feel like there’s nothing they can do on a personal level to reduce their carbon footprint or support projects that reduce carbon emissions.
It’s not a novel concept. In 2004, TerraPass launched its service to provide carbon offsets for consumers. The company was acquired in 2014 and now operates as a subsidiary of the publicly traded Canadian retail energy company, Just Energy.
Since TerraPass, other organizations have come in with services to offset consumer and corporate carbon emissions. The Swiss nonprofit MyClimate is another organization working on offsets for corporations and individuals (as is the German nonprofit, Atmosfair) and the North American public benefit corporation, NativeEnergy also has both a retail and corporate offset program.
Project Wren sources its offset investments from Project Drawdown and is trying to choose the projects that the company’s founders consider “most additional,” according to Brand.
Brand, Stanfield and Tran Zambetti met at USC while pursuing a bachelor of science degree in USC’s new Jimmy Iovine and Andre Young Academy. Iovine and Young are the co-founders of Beats, which sold to Apple for roughly $3 billion, but perhaps are more famous for their work in the music business as the co-founders of Interscope Records (Young is the rapper and producer known as Dr. Dre).
From the outset the three students worked together on side projects and in student organizations, and decided last year to launch a sustainable business that could impact consumers in a positive way. The first idea, and the one that was initially incorporated as Project Wren, was to develop an algorithmically enhanced software service to promote diversity and inclusion in companies.
“The idea was promising, but it’s a hard product to sell. Companies aren’t used to leveraging software to help build their culture,” Brand wrote in an email. “Trying to get people to use the product made us realize how difficult it is to build something that’s useful and good for the world. If we were going to build a company around doing good, it would take a decade or more.”
The group convened earlier this year and decided, after spending a year working on their idea, that the more than 10 years it would take to build a successful business was too long for them to see the impact they wanted to make in the world. “We felt like the mission of making companies a better place to work was important, but not urgent,” Brand wrote to me in an email. “Climate change is urgent. It’s the biggest challenge humanity has ever faced. That’s why we decided to pivot.”
The group then decided that they would pool their resources on another project — a vegan cloud kitchen that could potentially become a franchise or chain.
“Meat production is responsible for as much as 20% of greenhouse gas emissions,” Brand wrote. “If we could make eating vegan food easier than eating meat, we would have a huge impact.”
The group ran a cloud kitchen out of Brand’s apartment for two weeks before deciding that, too, ultimately was a wash for the three young co-founders.
With that idea behind them, the three began researching carbon offsets, which led them to Project Drawdown, which led them to build their current website and, ultimately, Y Combinator .
Customers who buy offsets using Wren will support projects that the company has selected for their additionality (meaning the projects would not have been done without the support of organizations like Wren). Once the offsets are purchased, Project Wren retires them from circulation so they can’t be traded on any exchange after their creation.
The company makes money by taking a 20% commission above the price of the project for operating expenses and marketing, says Brand.
What Brand sees as the young company’s competitive advantage is its ability to communicate more directly with a new audience of offset acquirers — engaging them more in the process by providing updates on the project.
“Photos, and stories too, from people on the ground will add a more human, real, touch,” to the projects and their reporting back to carbon offset buyers, according to Brand. “We just talk to a bunch of potential partners and see which partners would be able to give unique compelling updates to our users.”
