Renewable Energy

Business secretary John Hutton's plans to see a new coal-fired power station under construction this summer suffered a significant setback after E.ON, the company behind the proposed plant at Kingsnorth in Kent, asked him to delay the decision on whether the plant should be built.

Until now Hutton's Department for Business Enterprise and Regulatory Reform (Dberr) and E.ON had both been pushing for a decision to be made by 'end May 2008 at latest'. According to documents obtained by Greenpeace under the FoI Act, E.ON's plans were so advanced that contractors had already been secured to commence building work 'from summer 2008 on current tenders'.

Due to popular demand (well, demand anyway), The Weekly Geek now has its very own RSS feed.

Back in 1882, Thomas Edison built the United States' first electric power plant. Pearl Street Station, which supplied the good folks of Lower Manhattan with electricity for lighting and steam for manufacturing, was around 50 per cent efficient.

125 years on, the typical UK power plant is just 38 per cent efficient. But those modern power plants that have been built on the same principles as Edison's are reaching efficiency levels of up to 95 per cent.

So how did Edison do it? And where are we going so wrong?

In this week's slightly tardy Weekly Geek, we're looking at combined heat and power (CHP): the system Edison was using, and the heart of any truly clean and efficient decentralised energy system. (Those who read the first Weekly Geek on decentralised energy may notice a fair bit of crossover.)

This combined heat and power plant in Denmark is up to 95 per cent efficient

To celebrate our launch of EfficienCity, we're starting a new, weekly column for all the closet energy geeks out there. Every week, we'll take an in-depth look at one of the technologies we feature in EfficienCity - tidal power, wave power, wind energy, combined heat and power, micro-hydro power, anaerobic digestion, biomass and the rest. We'll also be looking at issues like baseload and the regulatory context for decentralised energy.

So remember to check back each Wednesday and, if you have any suggestions for energy solutions to climate change you'd like to see us cover, just post a comment at the bottom of this page and we'll try to slot it in.

You wouldn't necessarily expect the Financial Times, that bible of the corporate world and the money markets, to be a champion of environmental causes but they've been upping the ante on renewable energy, specifically wind power.

This week, they've been publishing a series of articles and news reports on the UK wind farm industry and they've been particularly critical of how various government policies, which were put in place to encourage the development of renewable energy industries, are actually having the opposite effect. It has been scathing about the renewables obligation, a mechanism which has all of us paying extra on our energy bills to subsidise new projects such as wind farms.
