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 …

Colorado Case Study Demonstrates In-State and Rural Economic Impacts from Wind Manufacturing and Plant Construction

NREL, Sept. 16, 2019 In-state wind turbine manufacturing and installation support both short-term and long-term jobs and account for other economic impacts, according to a National Renewable Energy Laboratory (NREL) case study of Xcel Energy’s 600-MW Rush Creek Wind Farm—Colorado’s largest wind energy project. NREL researchers who conducted the study also gained a deeper understanding of how wind plant construction …

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 …

Clean energy jobs are big in Minnesota. But they often go to people from out of state

By Walker Orenstein | 08/16/2019 in MinnPost.com The fastest growing jobs in the country are solar panel installers and wind turbine service technicians, a fact that clean energy advocates use as evidence of a growing sector and the economic upside of transitioning away from fossil fuels. But in Minnesota, the rise of clean energy isn’t always resulting in new jobs for Minnesotans — at least …

700 MW Wind+Solar+Storage Deal in Oklahoma is cheaper and battery will respond faster than a gas peaker can, plus the added benefit of absorbing excess capacity

‘Cheaper Than a Peaker’: NextEra Inks Massive Wind+Solar+Storage Deal in Oklahoma: NextEra will build a combined 700 megawatts for an electric cooperative group in a landmark deal for the hybrid renewables sector. By Julian Spector in GreenTechMedia, July 25, 2019 Oklahoma-based Western Farmers Electric Cooperative to build the largest proposed solar-plus-wind-plus-storage plant in the U.S. with even amounts of each. The battery …

How climate change is making hurricanes more dangerous: Stronger wind speeds, more rain, and worsened storm surge add up to more potential destruction

A 2013 study found a substantial regional and global increase in the proportion of the strongest hurricanes—category 4 and 5 storms. The authors attribute that increase to global heating of the climate: “We conclude that since 1975 there has been a substantial and observable regional and global increase in the proportion of Cat 4–5 hurricanes of 25–30 percent per °C of anthropogenic …

Guess What’s Holding Back Wind Power in the US? No eminent domain for electricity

One man’s failed attempt to build a transmission line illustrates a unique American obstacle to clean energy.By Peter R. Orszag July 10, 2019, Bloomberg, “Guess What’s Holding Back Wind Power in the U.S. “ Peter R. Orszag is a Bloomberg Opinion columnist. He is the chief executive officer of financial advisory at Lazard. He was director of the Office of Management …

Natural Gas Beat Coal in the US. Now Renewables and Storage Are Beating Natural Gas

Coal, the long-reigning king of the U.S. power sector, was officially dethroned by cheap, abundant natural gas in 2016. In 2018, natural gas fueled more than 60 percent of newly installed electric-generating capacity and accounted for 35 percent of total U.S. electricity generation. Now, even Indiana is rejecting new gas plants and Los Angeles has struck a deal on the largest and cheapest …
