from almost 10 percent of its energy use to 15 percent by 2020.
This dynamic is evident in Germany, where wholesale power prices are being depressed by must - dispatch, low - marginal cost
renewables, but balancing this intermittency is causing retail power prices to rise, both
from increasing FIT commitments, and increasingly with costs like
capacity payments for baseload power stations and curtailment payments for excess
renewables.
-- China in 2012 increased electricity output more
from non-hydro
renewables than
from all fossil - fueled and nuclear sources, and in 2013, added more PV
capacity than the US had added since it invented PVs in 1954.
Fully contracted
renewable energy projects have the least transition risk while older, inefficient merchant coal plants are likely to suffer disproportionately
from the financial effects of carbon transition such as lower wholesale prices, the cost of carbon credits, lower
capacity factors and increased operating or capital costs, according to the report.
