Plenty of renewables- and they can be balanced

There is more than enough renewable energy to meet global needs and the use of variable sources can be effectively balanced, according to new reports, with grid integration offering a way to limit shortfalls and curtailment risks.

UK Renewables can get to 80% or more

UK Renewables can get to 80% or more at low cost, says a new study from Imperial College. But we seem to be heading in the opposite direction, with renewables support being cut dramatically, and arguably, prematurely, while support for its rivals is being increased.

World Bank looks to renewable integration

The World Bank says that high renewable contributions can be integrated into power systems reliably at relatively low cost if attention is paid to developing and optimising the overall grid balancing system.
