Future Energy Alternatives
We are all fully aware of the current need to seek out environmentally friendly & renewable ways to generate energy. This necessity to move away from using energy manufactured from fossil fuels is due to that fact that this energy source is both non-renewable and a major contributor to global warming. With news that global warming is inevitable and calls from environmentalists and politicians alike to seek out alternative energy sources, it is clear that we need to act sooner rather than later. But what alternatives are readily available to us today? The carbon footprint that we leave when we travel is massive; be it by car, bus, train, or plane. Traditionally these (among other) forms of transport are powered by fossil fuels and make up a huge 14% of annual greenhouse emissions. However, in today’s world there are more eco-friendly options available. The electric car is one of these options; powered solely by electricity and with much lower emissions than the traditional combustion engine it seems that travelling by electricity is the way of the future. With lower band tax groups for low emissions vehicles, driving an electric car is also a cost effective way to drive. Another economical way to save the environment would be to install solar panels on your house. Although initially expensive to set up, once installation is complete additional costs on solar panels are minimal and solar energy is pollution free. Solar panels effectively convert usable sunlight into electricity using photoelectric cells or synchronized mirrors. The best thing about solar energy is, seeing as it is generated solely from sunlight, it is a 100% renewable energy source. An additional alternative resource to consider in for the future age is the power of wind. Although this resource is not available at a domestic level as of yet and only accounts for 0.1% of the world’s electricity demands, it is one of the cleanest and most efficient forms of energy available – providing the wind blows of course. Scientists hope that by, quite literally, relocating wind farms to the skies where the wind blows more consistently and stronger they could generate a larger yield of energy unaffected by lulls in wind flow at the earth’s surface. Unfortunately none of the above alternative energy resources are yet utilised to their full potential. However they do show promise for cleaner, greener and hopefully cheaper renewable energy options in the future.
