Many people are sick to death of the escalating cost of electricity, but they do not know what they can do about it. They have switched lights off; they have not turned lights on; they have unplugged devices on stand-by and they have turned the central heating down and the air con up and it has only saved them pennies. Yet still the electricity bills go up on a regular basis. It is very frustrating.

We have all heard of alternative and sustainable sources of energy, but the question is: how can average people implement these technologies into their own homes? One phone call to a professional solar power installation company will convince anyone that solar power is only for the well-off.

Likewise with wind power generation. A single device, which may or may not satisfy the electrical needs of one standard household will cost in the region of $45,000 and it is thought that, if it meets expectations, that it will pay for itself in ten years time. $45,000 is too much money for most people, but having to wait ten years to realize that investment is too long for most individuals too.

So, at first glimpse, it looks like the average person is at the mercy of the oil companies and the electricity generators. However, it does not have to be like that. There are other ways of tackling the problem and extricating yourself from the clutches of energy providers. The first technique would be to buy the solar power units and install them yourself. That would save you a great deal, perhaps up to 50%. But you could go a stage further and make the solar panels yourself too, which would save you a great deal more money.

The fact is that the more of your own labour that you can put into the scheme, the more you will save, because the labour constituent in any task usually amounts to about 50% of the costs. We all know how expensive it is to call a plumber in to fix a leaking pipe or a roofer to replace a slate. $100 for a slate? $100 for a dribble of solder? No, it is the tradesman’s time and the same is true of solar panel fitters.

The way out is to learn how to assemble the solar power units and fit them yourself. It is not hard. Any teenager can can learn how to do it and so can you. Believe me, learning how to assemble and fit solar panels is not difficult. Just try it and see for yourself. You will amaze yourself and your friends. You may even transform it into a business!

The thing to do is get a reliable kit or a plan from a trusted source. This could be a neighborhood hardware or hobbyist store or from a specialist website on the Internet. Once you have your design, you can buy the components. They are commonplace and available in most DIY shops. Then it will take you about a day to construct a solar panel that will provide about 100 watts.

This may not seem like much, but it will power many types of small machines or two average light bulbs. The trick is to keep adding to your stock of solar panels until you are entirely free of the electricity grid or even selling electricity back into it.

One of the latest issues that has almost everybody concerned is global warming. The climate is changing and the prognosis doesn’t look good. Global warming refers to the unabated rise in the average temperature of the planet as brought about by the increased concentration of greenhouse gases in the atmosphere. Many believe that the use of alternative energy sources will reduce carbon emissions and that will help hold back global warming.

Greenhouse gases are created by both natural processes and human activity. The major greenhouse gases are water vapor, methane, carbon dioxide, ozone, nitrous oxide, and chlorofluorocarbons (CFCs). There are many causes of greenhouse gases but the primary culprit is the consumption of fossil fuels that continued to release carbon dioxide to the atmosphere. Deforestation compounded the problem because trees and plants are supposed to absorb the carbon dioxide but now there’s not enough of them left to do the cleanup of the atmosphere

Scientists also blame the use of CFCs in refrigeration systems and in fire fighting, and other manufacturing practices in producing the greenhouse effect. Even the application of non-organic fertilizers in commercial farming operations also gives rise to another greenhouse gas, nitrous oxide.

According to the US Energy Information Administration, the presence of greenhouse gases in the country can be traced primarily to the burning of fossil fuels. Official figures for 2006 place the contribution of using coal, natural gas and petroleum to local greenhouse gas emission at about 82%. On the other side of the globe, China is seen to add more than its fair share of greenhouse gases because of the many traditional power plants that were just built in the country’s inner regions. Greenpeace, on the other hand, reports that the current levels of carbon dioxide in the atmosphere are the highest within the last 150,000 years with the 1990s as the warmest decade and 1998 as the warmest year in recorded history.

If mankind will not keep in check the various activities that continuously discharge greenhouse gases, humans will experience a drastic climate change over the next century at a much faster rate than has been observed in history. All is not lost, however. There is still time, although it is very short, to undertake sweeping measures to rein in the emission of toxic gases that are bound to kill all of mankind.

The most critical step is the efficient use of energy through the reduced consumption of fossil fuel primarily oil, petroleum, and coal. Man should use energy that comes from renewable sources like the sun, wind, ocean, and biological material.

Energy that does not harm the environment when used is termed green energy. It usually comes from the renewable, natural sources. There are several methods to generate clean and safe energy from renewable sources. Electricity generated through wind turbines, solar panels, and from geothermal plants cost much less and emit little to no carbons compared to coal and gas-powered plants.

Cutting down global dependence on fossil fuel and increasing the use of alternative energy sources is said to be one of the more effective solutions to the threat of global warming. Per Greenpeace projections, the efficient utilization of renewable sources can supply half of the total energy requirements by the year 2050. Same projections also estimated a near 50% reduction in carbon dioxide emission within 43 years.

Governments around the world are instituting measures to shift energy sourcing from the traditional to the alternative sources. In March 2007, leaders from the European Union agreed to joint efforts in cutting emissions of carbon dioxide and other greenhouse gases. To achieve this, they will need to obtain at least 20% of their power requirements from renewable sources. The deadline was set to 2020. Many governments provide tax credits and other incentives to businesses and private individuals who use green energy.

Resorting to alternative energy sources is only one way to cut down on toxic gases but there are many other ways that humans can help in the world wide effort to alleviate the greenhouse effect and curb global warming.
