Much of the focus on the energy crisis in the UK has been upon the cars we drive, and with good reason. Cars burn fossil fuels, creating smog consisting of greenhouse gasses, which then traps the heat of the sun and warms the environment. This causes global warming, which is a very real threat to our continued well-being as a species.
But you shouldn’t just focus on your car. Energy conservation at home can help play a part in the energy crisis, and electricity conservation can also put a few pounds in your pocket at the end of every month.
I always remember learning this basic fact that, for each degree you lower your heat during the winter, your heating bill will be roughly 3% less. An added bonus of running cooler in winter is that you don’t feel the cold as much and you burn up to 100 more calories a day, without any effort.
This applies in the summer as well, with the preponderance of air conditioners from DIY outlets going full blast morning, noon and night. When it comes to electricity conservation, it’s a year-round concern.
Why? Well,the risk of global warming is a real threat that could have devastating consequences.
The following is from wikipedia.org’s entry on the subject:
Global warming is the increase in the average temperature of the Earth’s near-surface air and oceans since the mid-20th century and its projected continuation. Global surface temperature increased during the last century. The Intergovernmental Panel on Climate Change (IPCC) concludes that increasing greenhouse gas concentrations resulting from human activity such as fossil fuel burning and deforestation caused most of the observed temperature increase since the middle of the 20th century. The IPCC also concludes that variations in natural phenomena such as solar radiation and volcanoes produced most of the warming from pre-industrial times to 1950 and had a small cooling effect afterward. These basic conclusions have been endorsed by more than 40 scientific societies and academies of science,[B] including all of the national academies of science of the major industrialized countries. A small number of scientists dispute the consensus view.
Climate model projections summarized in the latest IPCC report indicate that the global surface temperature will probably rise further during the twenty-first century. The uncertainty in this estimate arises from the use of models with differing sensitivity to greenhouse gas concentrations and the use of differing estimates of future greenhouse gas emissions. Some other uncertainties include how warming and related changes will vary from region to region around the globe. Most studies focus on the period up to the year 2100. However, warming is expected to continue beyond 2100 even if emissions stop, because of the large heat capacity of the oceans and the long lifetime of carbon dioxide in the atmosphere.
An increase in global temperature will cause sea levels to rise and will change the amount and pattern of precipitation, probably including expansion of subtropical deserts. The continuing retreat of glaciers, permafrost and sea ice is expected, with warming being strongest in the Arctic. Other likely effects include increases in the intensity of extreme weather events, species extinctions, and changes in agricultural yields.
But even if you drive is not to combat global warming, being energy efficient means you can have more money for those “rainy days” that can catch us out once in a while.
