READ MORERecent work found that renewable energy could supply 80% of electricity demand in the contiguous United States in 2050 at the hourly level. This paper explores some of the implications of achieving such high levels of renewable electricity for supply chains and the environment in scenarios with renewable supply up to such levels.
READ MOREIncreasing the renewable energy penetration further above 70% sees the need for storage become more significant, as the ability for PV and wind alone to meet the demand becomes strained, and the system costs increase due to the addition of storage.

READ MORESince 2002, the penetration of non-hydro renewables in supply have increased from only 2 percent to 22 percent in 2012. The bulk of generation from new renewables, as in Portugal, is from wind energy. In 2011, wind energy contributed more than 15 percent of supply; solar more than 3 percent; and biomass nearly 2 percent.

READ MOREAccording to analysis from IRENA [], a decarbonization of the power sector, in line with the climate objectives outlined in the Paris Agreement, would require an 85% share of renewable energy in total electricity generation by 2050 that time solar and wind power capacity would account for 60% of the total power generated. The
READ MOREIn 2022, renewable energy supply from solar, wind, hydro, geothermal and ocean rose by close to 8%, meaning that the share of these technologies in total global energy supply increased by close to 0.4 percentage points, reaching 5.5%. Modern bioenergy''s share in 2022 increased by 0.2 percentage points, reaching 6.8%.
