Mankind’s insatiable hunger for energy has resulted in a phenomenon scientists call the ‘greenhouse effect’. What the term really means is that because of the production of toxic gases through the burning of fossil fuels the upper layer of earth’s atmosphere has become like an envelope that acts as a heat-trap. This has led to an alarming rise in global temperature. Scientists use the term ‘carbon footprint’ to refer to the aggregate of all the greenhouse gases produced as a result of an individual’s activities such as driving a car.
What is the best way to reduce the emission of greenhouse gases? The answer lies, of course, in the use of clean energy. When talking of clean energy, three technologies come into mind immediately: hydropower, wind power and solar power. Hydropower is widely used but with the cost of production rising every year it is becoming increasingly expensive. Wind power is not available everywhere. That leaves solar power which is universally available and is in exhaustible supply.
Solar power is the use of sunlight to produce energy for various purposes. It can be used as a direct source of heat, for example to heat water for domestic use and even to cook food. More importantly, it can be used to produce electricity. This can be done by installing a solar home electric system that consists of one or more solar panels, a set of batteries and an inverter. For DIY enthusiasts, DIY solar panels are a possibility and can be installed easily without the help of experts.
Before installing solar panels, it is advisable to do a home energy audit. This gives you a pretty good picture of how much electricity you actually need and how much you’ve been wasting, if any. You can do it by yourself or have a professional from a power utility company do it for you. After determining your requirements, you can have solar panels installed or, go for DIY solar panels.
Another way to conserve energy and save resources is to install solar pool covers if you have a swimming pool. This helps prevent the loss of water through evaporation in hot weather and keeps the water warm in winter. A solar pool cover also helps keep the water clean and hygienic. You should also consider other ways to conserve energy are to turn off lights and appliances when not in use, replace incandescent light bulbs with CFLs or LEDs, install solar water heaters, insulate ceilings, etc.
