A change in chemical composition enabled scientists to boost the longevity and efficiency of a perovskite solar cell developed at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL). The new formula enabled the solar cell to resist a stability problem that has so far thwarted the commercialization of perovskites.
The share of variable renewable energy (VRE) — mainly solar and wind — generation on U.S. regional power systems more than doubled on average from 2012 to 2018, according to the newly released 2018 Renewable Energy Grid Integration Data Book.
The cumulative value of residential solar installations for utilities is comprised of two different parts: the generation of electricity to the grid, and the avoided cost of building new generation. While the former is fairly straightforward and owners are compensated through net metering or other rate schemes, the latter is difficult to assess and thus far homeowners have received little compensation.
The cutting-edge research at the U.S. Department of Energy’s (DOE’s) National Renewable Energy Laboratory (NREL) will one day go to waste—but not into a landfill.
The National Renewable Energy Laboratory, which regularly publishes a chart of the world’s most efficient solar cells, has introduced a new chart of record-efficiency solar modules.
A number of people made some really interesting comments on my recent CleanTechnica article, “Mark Z. Jacobson & The 100% Renewable Energy Naysayers.” Some of these had to do with the problem of getting the last 20% of our energy from renewable sources, after we got to the 80% mark.
Remember a few short years ago when the hot debate was whether cars in the future would be predominantly powered by fuel cells versus batteries? And even more fundamentally, if electric vehicles would ever move beyond the niche “green” and luxury-performance buying market? My how sentiment seems to have changed recently.
