Scientists agree that the world is warming, & that human activity is substantially the cause.1 Cost, both in financial terms2,3 & impact on human well beings,3,4 is enormous.
Electricity generation is a substantial source of greenhouse gases. A 100% renewable grid is thus, essential. Good news is that such a grid is also feasible according to a paper recently released by the Alternative Technology Association (ATA).
