Using fossil fuels more efficiently
One way to help reduce carbon emissions and thus help prevent climate change is to use fossil fuels much more efficiently.
An example - Combined Heat & Power
In the UK, large amounts of coal are burned to create electicity. Most of these power stations were built in the 1950s and are reaching the end of their lifespans. Many are due to be replaced in the next few years.
They are very inefficient, wasting much of the energy contained in the coal as waste heat.
This video from Greenpace looks at how it could be possible to make much more efficient use of existing fossil fuels, so that we use less. Examples from the Netherlands show that by using very much smaller power generating systems located within cities, the waste heat can be used to heat buildings. This method is known Combined Heat & Power (CHP).
