ENERGY CONSERVATION AND RENEWABLES

Jeremy Leggett, the founder and chairman of company Solarcentury, has made some of the most sensible comments on "the greenest government ever" during the past week.

Whilst welcoming the Coalition's new targets for cuts in UK carbon emissions by 2025, Mr Leggett has also pointed out the present government's "emerging record" on the environment is "actually starting to look worse than their predecessors"(Cameron falls short on his green promise, Financial Times, 18 May 2011).

Meanwhile, Japan is still coming to terms with the consequences of nuclear disaster, including major electricity shortages. Energy conservation is now regarded as one of the country's most important tasks, along with harnessing plentiful geothermal power opportunities.

For renewables to make a contribution to energy production of the scale aspired to by the non-nuclear green movement, the starting point is cleary conservation, something their recent great misfortune has brought home to the Japanese.

The development of renewables then has to be locationally-appropriate, something which has not fully registered with promoters, largely due to the availability of inappropriate financial incentives.

In addition, a truly renewable energy future would depend on unprecedented international co-operation, with energy transmission supergrids deployed to distribute power from different regions of the globe according to the availability of supply and demand.

These are the sorts of issues which politicians, policy-makers, those concerned with implementation as well as the media should be headlining. Instead we have the much-feted "Jam Tomorrow Generation" (see my post of 11 May) fiddling as usual whilst the planet burns.
