The optimum mix of storage and backup in a highly renewable, highly reliable European electricity grid
We estimate the variability of solar and wind energy generation potential in Europe over a 43 year period between 1980-2022 with the MERRA-2 reanalysis datasets. We compare the estimated supply potential to hourly demand data from 36 European countries to calculate the reliability of a highly renewable electricity grid in Europe. We find that in cost-optimised scenarios with onshore wind, solar and storage, but no natural gas, reliably meeting the last 1% of demand represents 36% of the entire …

More than nine in 10 renewable power projects globally are now cheaper than fossil fuel alternatives.
Solar power is about 41% cheaper than the lowest-cost fossil fuel alternative,
and onshore wind generation is less than half the price of fossil fuels, according to a report from the International Renewable Energy Agency.
Costs have been driven down by the increasingly widespread use of the technologies,
a huge focus on low-carbon manufacturing in China,
and bu…

South Africa approves six solar projects totaling 1,290 MW
An additional six solar projects have been approved as part of South Africa’s seventh renewables procurement round following the reallocation of unused onshore wind capacity to solar bids.
