We are surrounded by sources of power. Sun, wind, rain, tide, hamsters scurrying round their wheels . . .
These weather-generated sources are each at their peak in different circumstances and places. There is no point in taking one source, like wind-power, and saying that it won't be enough on windless days. We have to develop ALL the ways of making electricity, find and use the most efficient way to tap them, and then amalgamate them all into one system which had draw on whichever is most productive at any given time, and w
