Why 30 Million Solar Rooftops Should Be In the Next Relief Bill: More than 1 in 3 home or business rooftops in America is suitable for solar. With $450 billion in rooftop solar, the federal government could slash energy bills for Americans, cut air pollution, create over 3.7 million jobs, and get paid back!

By JOHN FARRELL  10 APR 2020  As the federal government looks to a second (or even third) stimulus bill, Congress should consider a huge opportunity to pay Americans that pays back: solar rooftops. Somewhat more than one in three home or business rooftops in America is suitable for solar: sunny with sufficient space to host a few panels. By investing $450 …

Fraunhofer ISE Testing Vehicle-Integrated Solar Systems that will meet 5% of power needs, such as refridgeration

Steve Hanley, Clean Technica May 2020 Fraunhofer ISE is partnering with the Fraunhofer Institute for Transport and Infrastructure Systems and four trucking companies to develop vehicle-integrated solar systems that can help reduce carbon emissions from the transport industry. As part of the research, Fraunhofer ISE has equipped several trucks with sensors that record how much solar energy they are exposed to …

Rooftop Solar Wins Big in Kansas Court Ruling from Conservative Judge

Dan Gearino, Inside Climate News, April 9, 2020 The Kansas Supreme Court has provided a rare and sweet victory for renewable energy advocates in the state, with national implications. The court issued a unanimous ruling on Friday agreeing with advocates that a 2018 utility rate plan was discriminatory in the way it created a new charge that inflated the bills of rooftop …

Designing High Wind -Resilient PV Systems

Solar Under Storm Part II: Designing Hurricane-Resilient PV Systems February 17, 2020  |  By RMI, Laurie Stone and Christopher Burgess The last three years have seen major hurricanes wreak havoc on island nations. Hurricanes Harvey, Irma, Maria, and Dorian caused catastrophic damage to homes, infrastructure, and economies throughout the Caribbean basin. At the same time, the use of solar photovoltaic (PV) power …

Renewable energy prices are now significantly below those for coal and gas generation. It is now cheaper to save the climate than to destroy it.

Over the last decade, wind energy prices have fallen 70% and solar photovoltaics have fallen 89% on average, according to Lazard’s 2019 report. Utility-scale renewable energy prices are now significantly below those for coal and gas generation, and they’re less than half the cost of nuclear. The latest numbers again confirm that building new clean energy generation is cheaper than running existing …

The water-energy nexus at rivers can be resolved worldwide by 2050 as a consequence of the energy transition

Water-energy nexus can be resolved for thermal power plants #100RE. 96% of global thermal PP and 330 rivers are individually traced. 98% of water consumption can be avoided Water and energy are closely related, particularly in the current electricity generation based on thermal coal, gas, oil and nuclear power. The so-called water-energy nexus is a significant sustainability concern. However, a …

Accelerating Wind and Solar: Wind and solar have seen remarkable growth over the past few decades. Most of the limits on wind and solar integration that have been presented by critics have been proven overstated at best, if not outright false.

Solar represented only 2.4 percent of global electricity generation during 2018. However, the rate of growth is dizzying. The output from solar grew around 50 percent annually from 2007 through 2017, meaning that on average, its contribution to the power supply more than doubled every two years. Wind is further along, representing 5.5 percent of generation in 2018. However, it has been growing …

Solar farms can keep the lights on even at night: Trial shows panels can smooth voltage fluctuations in the UK National Grid

“Inverters” at the solar farm are usually used in the process of converting solar energy to electric current. But at night, when the grid is often less stable, the same equipment can adapt grid electricity to a healthier voltage. Chris Buckland, technical director of Lightsource BP, said the inverter acts like a distortion mirror by reflecting the energy network’s voltage …

Supporting an accurate value of solar

John Farrell, ILSR, Nov 2019, excerpt Minnesota’s value of solar policy had the benefit of development on the heels of successful value of solar policies in other jurisdictions, primarily Austin, Tex. The included components were written specifically into the enabling legislation based on the advice of experts from municipal utility Austin Energy, Clean Power Research, and clean energy economists. The …
