Today, 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.Read More

How very sensible of you to recommend trams as the preferred solution for public transport in urban areas. I attach a note on the potential for integrating waste recycling with ultra light trams. If really good tram networks are installed (and the cost of installing lightweight rail has now been brought below £2 million per route kilometre double track) then, together with pedestrianisation, cycling and rickshaws, urban mobility can be brought to a very high level before having to bring in a few electric taxis.
Unfortunately I cannot get any of the relevant Departments in Government even to discuss these proposals, although Jonathon Porritt has now volunteered to take up the issue. I attach a copy of a letter to Hoon which still awaits a reply. The programme I am suggesting could easily be funded from a progressive transfer of money from the so-called Bus Service Operators Grant which spends some £400 million a year in subsidy to reduce the cost of fuel for diesel buses! The waste needs to be recycled urgently to prevent methane emissions to the atmosphere and to take some of the strain off landfill.Read More
