The Convenient Solution

A short film about climate change and energy

We all know that, to stop climate change, we need to stop burning fossil fuels. The government says we need nuclear power to do this. Our new film explains why nuclear power can’t stop climate change – and lays down a better, cheaper, more convenient solution:

Not convinced yet? Read on.

The single biggest use of fossil fuels in the UK isn't for electricity or for transport, but for creating heat to warm our buildings and power our industrial processes. So any solution to climate change needs to contribute to heating, as well as to electricity generation.

Nuclear power contributes almost nothing to our enormous heating requirements. In fact it contributes less than four per cent to our overall energy needs. And building new nuclear power stations (as the government wants to do) won't increase that share.

So what is the solution? Well, in the same amount of time and for less money, we could implement an energy system that will do far more to stop climate change and ensure energy security than nuclear power: a combination of renewable energy, efficiency, and combined heat and power:

Royal Brewery

Archive content: last updated 13 July 2007

The Royal Brewery, in Moss Side, Manchester (the home of Fosters, the second biggest selling lager in the UK) is well over a century old, but is now years ahead of its competitors in dealing with the energy used on site.

EU League Table on share of renewables
When heat and transport energy is included, the UK ranks near the bottom for renewables development. Only Belgium, Cyprus and Malta are worse.

Energy isn't just wasted in the places that we finally use it; most of the waste in our electricity system happens before it even reaches our homes and businesses.

Our power stations throw away the same amount of heat as is needed to provide hot water and heating for every building in the UK.

DE in action

How does this happen? Well, generating electricity produces huge amounts of 'waste' heat, which is simply thrown away by our power stations - for example, as steam up the cooling towers.

On average, our large, centralised power stations throw away two thirds of the energy they generate.

The way we use energy is shockingly wasteful. Every year, we throw away more than eight times the amount of energy supplied by all of the UK's nuclear power stations combined.

Through our inefficient use of energy (gas guzzling vehicles, badly insulated buildings, poorly designed appliances etc) we needlessly throw away almost a third of the energy we use (source).

MEPs show themselves to be a bit dim

The numbers are in and sadly they weren't quite what we were hoping for. Despite the huge amount of emails you sent to MEPs, asking them to support a ban on inefficient light bulbs across the EU, not enough signed up to adopt the declaration.

Sharing is good, especially when it involves cars

Treehugger reminds us that tomorrow is National Liftshare Day, when everyone is encouraged to make sure as many seats as possible are filled for those essential car journeys.

A zero-carbon home of one's own

Greenpeace volunteers on John Prescott's roof, with the solar panels they kindly installed for himIn the news today are reports of the first zero-carbon home being unveiled in London. Housing minister Yvette Cooper has been touring the site, nodding in a ministerial way at the insulation, solar panels, water recycling and construction methods that went into the first home to meet the top standards of the government's sustainable housing code.

According to the report on this morning's Today programme (you can listen again for the next seven days), the ultra-efficient abode cost 40 per cent more to build than a 'normal' house but as more are built, the economies of scale will bring that down. As the government intends to make all new housing zero-carbon by 2016, that price fall should start in the near future, although Cooper was evasive when quizzed about exactly how many of the 160,000 homes planned in the Thames Gateway region would be zero-carbon. A rolling increase in standards was all she would commit to.

Compact Fluorescent lamp (CFL)

These two bulbs might look pretty similar but, beneath the surface, there are some important differences.

The bulb on the left uses five times less energy than the one on the right. It lasts up to 12 times longer. It can save UK consumers around £1.2 billion in electricity bills per year. It’s available for less than a pound from several major retailers.
