Renewable energy: vision or mirage?
— As renewable energy sources produce power intermittently, they cannot replace gas, coal and nuclear generation, even with further development. — Solar and wind energy have no prospect of becoming economically competitive in an unrigged market. Government intervention will lead to higher energy costs and jeopardize energy security. — Increased investment in wind turbines will do little to reduce carbon emissions and fossil fuel consumption. The report ‘Renewable Energy: Vision or Mirage?’, released today by the Adam Smith Institute and . . . Complete article »

Cost of pumped hydro storage
Apart from hydropower, virtually all of the new renewable energy technologies suffer from one serious problem. A problem that, to my knowledge, there is no solution in sight. We simply do not have an efficient, low cost technology for storing large quantities of electrical energy for periods of hours, days and months. Until this is invented, no intermittent renewable energy technology can be used on other than a relatively small scale. The only available technology for storing large amounts of . . .

Likely cost of electricity from Project Hayes
3.8 Wind power stations impose additional frequency keeping costs on the power system that are greater than, for instance, from hydropower stations. From the point of view of system operation, the major problems with wind power are that it is unpredictable and that it can fluctuate very rapidly. These rapid fluctuations means that with wind power connected to the system, frequency keeping becomes more difficult and more expensive. At the moment, frequency keeping plant operates to manage fluctuations in the . . . Complete article »
