The Best Place for Harvesting Solar Energy Is Not ...

And the same land can produce loads of food and electricity simultaneously. Even after a boom in recent years, solar energy delivers less than 2 percent of power generation to the US electrical grid. But if we’re going to avoid the worst impacts of climate change, the sun’s contribution is going to have to ramp up dramatically. Where to put all the solar panels? You might envision vast solar farms stretching across the...

NASA analysis sheds light on Cleveland area’s roof...

The federal study calculated rooftop solar potential adjusted for roof slope, shadows, and other factors Widespread deployment of rooftop solar in a 5.4-square-mile section of Cleveland could produce enough electricity to power approximately 10,000 homes, according to a new analysis by NASA researchers. The study, which used aerial images to calculate rooftop solar capacity, found the potential for more than 100,000 megawatt...

The Energy Transition in 4 Charts

There is little debate that the energy transition is underway. However, the speed at which it is happening is very much in flux. Wood Mackenzie recently compiled some of its latest power and renewables forecasts into a presentation (available here) that shows its most recent outlooks across sectors. Here are a few of the highlights. Carbon emissions WoodMac’s analysts modeled a few different emissions scenarios in...

Solar Panels on Farmland Have Huge Electricity-Gen...

Putting solar panels on less than 1 percent of the world’s agricultural land could produce enough energy to fulfill global electricity demand, according to a recent study published in the journal Scientific Reports. The research also concludes that solar panels perform more efficiently in cool, breezy, and dry conditions — findings that defy the common practice of installing large solar arrays in deserts. “Our results...

‘Coal is over’: the miners rooting for...

Appalachia’s main industry is dying and some workers are looking to a new economic promise after Trump’s proves empty. Set in a wooded valley between the Tug Fork river and the Mate creek, Matewan, West Virginia, was the site of the 1920 Matewan massacre, a shootout between pro-union coalminers and coal company agents that left 10 people dead and triggered one of the most brutal fights over the future of the coal industry in...

A solar-powered system can turn salt water into fr...

People have been trying to turn seawater into drinking water for thousands of years, but the process is not usually energy-efficient or affordable. At a newly constructed facility in Kenya, however, a nonprofit called GivePower is tackling that challenge using solar power. The desalination system, which started operating in the coastal area of Kiunga in July 2018, can create 19,800 gallons (75,000 liters) of fresh drinking...

(Ohio) Township solar project divides neighbors

In the countryside southeast of Yellow Springs, an area of rolling farmland dotted with homes and barns may someday be the site of a massive solar array. The Kingswood Solar Farm, if built, would span more than 1,200 acres in Miami Township, Xenia Township and Cedarville Township. And at an estimated 175 megawatts, it could be among the largest solar arrays east of the Mississippi River. Some area landowners are now signing...

Nuclear bailout bill is signed into law despite fl...

Gov. Mike DeWine signed House Bill 6 into law today after the Ohio House voted 51-38 — one vote over the 50 required to pass it — to approve the Senate version of the nuclear bailout bill and send it to DeWine’s desk for signature. The bill will require every Ohio residential electricity customer to pay about 85 cents a month, close to 90 percent of which will go to subsidize the Perry and Davis-Besse...

The ‘war on coal’ myth

Environmental regulations aren’t the reason that coal is falling off the map. Is environmental extremism causing the decline of the American coal industry? A look at the economics shows that coal has been beaten fair and square in the marketplace by cheaper and cleaner alternatives. The best way to support coal communities is to confront these economic realities, rather than creating a divisive and false narrative...

Lightyear unveils its ‘solar’ electric car with 45...

The Lightyear One, a new solar-powered electric car developed by several times Solar Challenge winners, has been unveiled today and the startup claims an unbelievable range of 450 miles (725 km) on a single charge. We have been reporting on Lightyear for a few years now. The startup first caught our attention because it spun out of Solar Team Eindhoven, a group of engineering students from the Technical University of...

After being rocked by Trump tariffs, the solar ene...

Key Points The solar energy industry has seen its share of ups and downs over the last decade, in part due to tariffs imposed by the Trump administration. After two years of job losses in the industry, however, advocates are projecting demand to pick up, thanks to state initiatives to promote the use of solar power. As business heats up, solar companies are facing a familiar problem — finding qualified workers. At...

Bees Invited to Denison Solar Array

Happy Bees!! Jeremy King led us on a walking tour this morning of the solar array at the Denison BioReserve to show off the pollinator splendor now blooming. More than 16 types of pollinating plants will be coming up this summer and the fall. Such an exciting first big step to show how renewable energy can “bee” beneficial to the environment. Share...

A 100% renewable grid isn’t just feasible, it’s in...

Europe will be 90% renewable powered in two decades, experts say. The myth that a very high level of renewables can’t be integrated into the electric grid is being demolished by the clean tech and battery storage revolution. “By 2040, renewables make up 90% of the electricity mix in Europe, with wind and solar accounting for 80%,” predict the experts at Bloomberg New Energy Finance (BNEF) in their annual energy outlook...

Electric vehicles (EVs) and batteries can drive gr...

Falling battery and EV costs with equal grid market access can accelerate transition to renewables: lessons from UK and Germany (LONDON) – The falling costs of batteries and electric vehicles can help drive the next phase of growth in renewables including rooftop solar power, provided small-scale renewables and storage have the same access to electricity and grid services markets as conventional power plants, according to a...

10 Mistakes I’ve Made Selling and Installing Batte...

The CEO of Silicon Valley’s Cinnamon Energy Systems boils down his biggest lessons from the residential battery business—from buggy software and interconnection delays to understanding customers’ emotions. In many regards, batteries are safer to install than rooftop solar, the author says. Upcoming electric rate changes in parts of the U.S. mean that almost every home and business here will eventually benefit from a battery...
