Your Energy Saving Could Be Doing Good More Than You Thought

August 1st, 2010 by admin Leave a reply »

We have all been encouraged to switch off – lights, televisions at the mains and don’t forget the computer, use the clothes line rather than a dryer and run the washing machine of a cooler setting. All great advice and we have been having a far bigger impact than we realised, according to a new study by the Grantham Institute for Climate Change looking at calculations used by the UK government.

UK government advisors have been estimating CO2 emission savings through energy efficiencies but their figures maybe as much as 60 per cent too low – meaning we save more than they have estimated.

The problem has been the vagaries in how power is generated. Power stations that burn fossil fuels produced higher emissions than nuclear or clean energy such as wind power. Generally only fossil duel fed power stations can react instantly to varying demand.
The author of the report, Dr Adam Hawkes, stated the the UK government needs to record the varying carbon emissions rates from the different power stations so they can set targets and make decisions based on firm scientific calculations.

In the study Hawkes suggests that ignoring low carbon emission power generation, such as nuclear and wind, and relying on figures from fossil fuel power stations which respond to changing demands provide inaccurate emission figures.

Presently scientists who advise the UK government use estimated figures to calculate emission rates, but the new study reveals that, at 0.43 kilograms of carbon dioxide per kilowatt hour of electricity consumed, this figure is 60 percent lower than the rates actually observed between 2002 and 2009, 0.69 kilograms of carbon dioxide per kilowatt hour.

Hawkes said:

“One way governments are trying to mitigate the effects of climate change is to encourage people to reduce their energy consumption and change the types of technologies they use in their homes. However, the UK government currently informs its policy decisions based on an estimate that, according to my research, is lower than it should be.

“This means any reduction we make in our electricity use – for example, if everyone switched off lights that they weren’t using, or turned off electric heating earlier in the year – could have a bigger impact on the amount of carbon dioxide emitted by power stations than previously thought.

“However, this also acts in reverse: a small increase in the amount of electricity we use could mean a larger increase in emissions than we previously thought, so we need to make sure we do everything we can to reduce our electricity use,” added Dr Hawkes.

Director of Imperial’s Grantham Institute for Climate Change, Professor Sir Brian Hoskins, added:

“This is a very important study that could help policy makers make more informed decisions to reduce our carbon emissions. The government needs a good understanding of the figures it uses to support policy analysis, because this has a big impact on which technologies we employ to reduce our energy use. With a more accurate picture of what is going on, we will be much better equipped to tackle our carbon dioxide emissions.”

    Energy is essential to life. Living creatures draw on energy flowing through the environment and convert it to forms they can use.We need to more efficient in use of energy.The higher the efficiency of a system, the less waste (usually heat) it will produce.Many commonly used systems lose up to 40% of their energy as wasted heat.Today, many converters can change energy from different sources directly into electrical energy with no resulting heat loss. The solar battery is an example of this type of converter.

    As I increase my awareness of what government agencies in the UK are doing around energy concerns and sustainability issues, I get envious. While in the states, there appears to be an interest, there is no incentives put in place for people to do anything about it.

    One such thing we have in the mortgage industry is an Energy Efficient Mortgage. We are trying to promote these as a new sales technique for our lagging real estate industry. You can read about it at http://www.swiftsureenergy.com/realestate or at http://homeenergytest.wordpress.com/ and I’d love to hear your thoughts on how you have done so well in the UK.

    Thank you for this interesting post. I am now trying my best to conserve as much energy as possible by switching off lights when not in use, recycling rather than throwing items in the bin.

    Every need to play their part by increasing their own efficiency,then we will be on our way to win the battle
