As the summer draws to a close and kids across the country prepare to go back to school, more eyes and ears are on the safety zones surrounding the schools than ever. Obviously, it’s critical that we ensure children are safe as they travel to and from these facilities. Regulations are in place to guide […]

Renewable Energy Renewable power is a hot topic in the world today. This is important for our planet because the energy we are using is harming us. Renewable power can be solar, wind, hydropower, geothermal, and biofuel as a beginning. These are clean fuels that comes from natural sources. They are becoming more and more […]

I’ve seen a few LCAs of algae fuel, and and the results are not particularly impressive. The IEA report includes algae in one […]

Read MoreToday, The Times has claimed that Britain’s potential renewable resources are insufficient to meet demand, and therefore that Britain needs new nuclear plants. This is reported as having been stated by the new Chief Scientific Advisor to DECC, Professor David MacKay FRS, the author of the free online book: Sustainable Energy Without the Hot Air – though it appears that The Times invented this quote. Nevertheless, the claim that Britain cannot live on its own renewables, is also made in his book.
However, the claim is not true.
On the professor’s own (underestimated) calculation of Britain’s renewable potential, it is possible for Britain to power itself from wind and solar. Current energy demand (heat, transport & electricity), is 98kWh per person per day (245GW), and the professor’s book identifies 68kWh/d (170GW) of wind onshore and offshore, and 55kWh/d (137.5GW) from photovoltaics, which together gives 123kWh/d (307.5GW). That means that even ignoring wave, tidal, geothermal and biomass, Britain’s renewable potential supply just from solar and wind substantially exceeds our energy demand.
