Why This Matters:It may be obvious, but we will need innovations like these to make the transformations needed to have a sustainable and feasible renewable power system. Combining solar and hydropower, according to the study, could produce the equivalent of as much as 40% of the world’s electricity. And a self-charging roadway would allow EV makers to use smaller, lighter batteries that would be replenished as we drive, making the whole system more efficient, inexpensive, and reliable.
According to the Department of Energy, the floating solar arrays technology is still in its infancy, but the research and development are farther along in Europe because they have less space for solar arrays on land. Thus far, the only actual installation of floating solar panels is in Portugal. E&ENews reported that “if floating solar panels were arrayed on more than 379,000 hydro reservoirs globally, the resultant hybrid could generate anywhere from 16% to 40% of the world’s 2018 electricity production, according to the study.” In addition, in places where there is evaporation in reservoirs due to extreme heat and lack of rainfall, such as the Southwestern U.S., such solar arrays sitting on the water’s surface might cut down on some water loss, one of the study’s authors surmises. Earlier NREL work estimated that installing floating solar panels on man-made U.S. reservoirs could generate about 10 percent of our annual electricity.
Besides here in the U.S. and now in Israel, solar road technology is being piloted in Sweden. The pandemic slowed down a project there, but it is getting back on track and when finished will involve 2.5 miles of road on the Baltic Sea island of Gotland. The electrified road will support an airport shuttle and an electric truck. How does it work? Copper coils installed under the pavement transmit energy from the grid wirelessly to a receiver attached under the EVs as they drive over it the vehicle charges. The company installing the solar road technology in Israel, Electreon Wireless, says nearly two-thirds of a mile of road can be outfitted during a single-night construction shift.
Getting more electric vehicles on the road is a crucial part of lowering greenhouse gas emissions and reducing air pollution. In addition to making EVs more affordable, charging must become more accessible and convenient–especially for people living in “charging deserts.” That’s where the mobile charging company, Spark Charge, comes in. CEO and Founder, Josh Aviv […]
Why This Matters: Car companies have long been allies of the fossil fuel industry. Now they are pivoting and expanding into EVs, not only pledging to reduce emissions but to go fully electric in coming decades.
by Natasha Lasky, ODP Staff Writer On Monday, the Biden administration announced that it had approved a $550 million solar energy project—named the Crimson Solar Project— with the capacity to power almost 90,000 homes. This project will be built on 2,000 acres of federally owned desert land west of Blythe, California. This area, halfway between […]
