Public Affairs went wrong on renewable energy

Gerard Jackson

His approach boils down to simply chanting that renewables are too costly, which is just another way of saying that they are less efficient than centralised power generation. It eludes him that the greens’ response is to argue that renewable energy will become more efficient if given enough time to develop......Every single member of our rightwing failed to grasp the simple and fundament fact that renewables just do not work. By this I mean that they cannot do the job that greens dishonestly claim for them. Expecting renewables to provide the vast amounts of energy required to drive an advanced economy is like expecting a Ford pickup to do the work of a 300 ton truck. It is a physical impossibility. The bald fact remains that so-called renewable energy faces insurmountable natural and economic obstacles........Now let us put these figures into perspective. The solar plant requires 33.3 times the area of the gas plant to produce a miserable 0.0197 of its output. (Remember: a gigawatt is 1,000,000,000 watts, so 3.8 gigawatts equal 3,800,0000,000 watts.) Therefore, to produce 3.8 gigawatts would have to cover 25,333.3 acres or 39.6 square miles as against 15 square acres. To top it off, this super-duper leap into the future can only produce electricity one-third of the time. Clearly, the insurmountable natural obstacle is energy density.....I stressed time and time again that a full-blooded attempt to switch the economy to alternative energy would be an economic energy is so dilute that it requires masses of land, labour and capital to produce a tiny fraction of the electricity that coal-fuelled or nuclear plants could produce with the same resources........ this is why solar plants will always be a total failure. ....To Read More.....
