Home Solar Energy System-alternative energy

Alternative energy is everywhere around us and it's possible to use it in many different ways. Solar power which is driven by photovoltaic cells is just one of these alternative energy sources that are increasingly becoming more advanced and less expensive. Solar energy is non-polluting and can be used to produce electricity in addition to hot water. Making use of the sun's energy is not that easy to do and requires a lot of labour for us to efficiently utilize it in a reasonable manner. The biggest downfall to solar power is it requires clear days so methods of storing this energy need to be found to cater for this and when night falls.
Wind energy has become the most invested in (by private investors and governments together) alternative energy source lately. Huge double and triple bladed windmills can be seen around the world, working constantly, day and night to produce large amounts of electricity. Windmills have been used for a number of centuries but it is only recently that they have been converted to produce electricity on an industrial scale. The windmills used today are massive compared to those used in the past and much more 'high-tech' and often referred to as 'wind-turbines'. Just like any other methods, using the wind energy has its own hitch such as having to worry what to utilize if ever the days are calm and still. Of course, the power we need can come from other sources when this happens so currently we cannot rely completely on wind power even if we had sufficient farms to cater for our needs.

Hydroelectric energy is available as a source of alternative energy, and it can generate a substantial amount of power. The concept of hydroelectricity is simple - using vast amounts of water and gravity to turn electricity producing turbines. The use of water for driving hydroelectric turbines is not much of a worry because water is just about everywhere. The main problem with this process is the initial financial cost and the size of these dams means it is a lengthy project which does not come without its own issues. Dams are often built in order to be able to control the flow of the water sufficiently to generate the needed power. Building a dam to store and control water's potential and kinetic energy takes quite a lot of work, and operating one is complex as well, and conservationists grow concerned that it is creating environmental problems.
If you don't need to supply the electrical needs of a city or an area with a huge population, then building a dam is overkill. One good alternative to consider is using small run-of-river hydroelectric converters to provide electrical needs to neighbourhoods or even to an individual office or home.
Probably the most underrated and under appreciated form of alternative energy is geothermal energy, which is simply the naturally occurring energy produced by the heating of artesian waters that are just below the earth's crust. The earth's inner molten core is the one responsible for transferring the heat into the water. There are various different methods for drawing up water to harness geothermal energy and they can be from dry steam power plants, flash power plants, and binary power plants. Steam is essentially gathered and for this reason, hot water should be drawn up. Approximately one hundred miles north of San Francisco lies 'The Geysers', probably the most famous of geo-thermal power fields where they use what is known as 'dry steam' power plant technology.

Alternative Energy Sources for the Home

Alternative Energy for the Home
The trend toward homes that are powered by alternative energy sources, ranging from wind turbines and solar collection cells to hydrogen fuel cells and biomass gases, is one that needs to continue into the 21st century and beyond. We have great need of becoming more energy independent, and not having to rely on the supplying of fossil fuels from unstable nations who are often hostile to our interests and us. But even beyond this factor, we as individuals need to get off the grid and also stop having to be so reliant on government-lobbying giant oil corporations who, while they are not really involved in any covert conspiracy, nevertheless have a stranglehold on people when it comes to heating their homes (and if not through oil, then heat usually supplied by grid-driven electricity, another stranglehold).

As Remi Wilkinson, Senior Analyst with Carbon Free, puts it, inevitably, the growth of distributed generation will lead to the restructuring of the retail electricity market and the generation, transmission and distribution infrastructure. The power providers may have to diversify their business to make up for revenues lost through household energy micro generation. She is referring to the conclusions by a group of UK analysts, she included among them, who call themselves Carbon Free. Carbon Free has been studying the ever-growing trend toward alternative energy-using homes in England and the West. This trend is being driven by ever-more government recommendation and sometimes backing of alternative energy research and development, the rising cost of oil and other fossil fuels, concern about environmental degradation, and desires to be energy independent. Carbon Free concludes that, assuming traditional energy prices remain at their current level or rise, micro generation (meeting all of one's home's energy needs by installing alternative energy technology such as solar panels or wind turbines) will become to home energy supply what the Internet became to home communications and data gathering, and eventually this will have deep effects on the businesses of the existing energy supply companies.
Carbon Free's analyses also show that energy companies themselves have jumped in on the game and seek to leverage micro generation to their own advantage for opening up new markets for themselves. Carbon Free cites the example of electricity companies (in the UK) reporting that they are seriously researching and developing ideas for new geothermal energy facilities, as these companies see geothermal energy production as a highly profitable wave of the future. Another conclusion of Carbon Free is that solar energy hot water heating technology is an efficient technology for reducing home water heating costs in the long run, although it is initially quite expensive to install. However, solar power is not yet cost-effective for corporations, as they require too much in the way of specialized plumbing to implement solar energy hot water heating. Lastly, Carbon Free tells us that installing wind turbines is an efficient way of reducing home electricity costs, while also being more independent. However, again this is initially a very expensive thing to have installed, and companies would do well to begin slashing their prices on these devices or they could find themselves losing market share.
