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 MOREAt present, renewables are cheaper than gas. A minimum cost of 69.05 £/MWh is found at a wind penetration of 57%. After this point, the TCoE starts to increase due to the increasing capex of the energy storage, which increases exponentially as the overall penetration of renewables approaches 100%.
READ MORE2023 saw a step change in renewable capacity additions, driven by China''s solar PV market. Global annual renewable capacity additions increased by almost 50% to nearly 510 gigawatts (GW) in 2023, the fastest growth rate in the past two decades. This is the 22nd year in a row that renewable capacity additions set a new record.
