Energy Resources
In spite of all the difficulties with fossil fuels, this plant is not without many other ways to produce power from what are known as ’alternative energy’ sources. An example that can be cited is one that is driven by photovoltaic cells called the solar power which in time can get more advanced and affordable. Solar energy power can be used for electricity, heating, and making hot water plus solar energy produces no pollution, as its input comes fully from the sun’s rays. However, much more work still needs to be done in order for us to economically harness the sun’s energy. One problem still to be overcome is storage of the collected power for ‘night-time’ use and when there the sunshine is not at its best.
As of now, a large number of private investors as well as the government take pride and support in investing for the utilization of wind energy as an alternative energy source. These are huge windmills with two but more often three blades which harness the power of the wind to generate electricity for many communities. We have used windmills for a number of centuries but it is only recently that they have been converted to produce electricity on an industrial scale. Modern wind turbines are simply are more advanced variations on the old theme. Just like any other methods, using the wind energy has its own issue such as having to worry what to utilize if ever the days are calm and still. Unsurprisingly, you cannot fully depend on wind energy during these times and this is where the electric company comes into action of powering your home or office.
Hydroelectric energy is available as a source of alternative energy, and it can generate a substantial amount of power. To generate electrical energy, turbines are turned by the downhill motion of water which its flow in response to gravity and that’s something essential that hydroelectric energy uses. As water is everywhere it has not generally been a problem finding locations where it can be employed. Having said that, building huge dams is very costly, time consuming and there are other challenges which usually make the whole process costly at the initial stage. To utilise this power, the dams that are built are large structures otherwise they will not be able to a) retain the water and b) have adequate water to run the turbines efficiently. Conservationists are starting to be worried about operating a dam as it not only requires a lot of labour building it to store and control water’s potential and kinetic energy but it can also be risky and complex. If you are not in the need to supply the electrical needs of a city or an area with huge population, then building a dam for it is not that necessary. There are small run-of-river hydroelectric converters which are excellent for supplying neighbourhoods or an individual office or residence.
When artesian waters just below the earth’s crust are heated, a naturally-occurring energy in the structure of geothermal energy can be produced which is more often than not the most underrated form of alternative energy that gains less of the gratitude and pride. Heat from the earth's core gets taken up by the water. A number of different ways are used to harness this ‘free’ power which is drawn up into power plants. The aim of drawing up the hot water is for the gathering of the steam. The Geysers, approximately 100 miles north of San Francisco, is probably the best-known of all geothermal power fields – it’s an example of a dry stream plant.
