Alternative energy research has led to the development of state of the art alternative energy sources for the home. One of the advantages of using alternative energy is that it is a renewable resource whereas our supply of coal and other fossil fuels is depleting. This advantage of renewable energy and alternative energies has many companies and people looking for different ways to power up.

Sometimes called renewable resources, alternative energy does not need fossil fuel or even the splitting of the atom to be produced. It is called renewable because the sources of it are constantly being produced. It does not cause the pollution that oil and gas cause. This kind of energy is not really new. What is new is that we now categorize these forms of energy as alternative energy.

The forms that alternative energy may take are fuel cells, geothermal energy, wind power, biomass, hydroelectric energy, solar energy and water energy such as wave and tidal energy.

*Fuel cells as a type of alternative energy is usually associated with electric cars, or hybrid cars. Electrochemical devices produce power through a chemical reaction. The primary benefit of fuel cells technology is that power is produced without the production of harmful pollutants. They are still very expensive to produce, however.

*Geothermal energy can be a powerful source of energy. It is ideal for small scale use to heat houses, businesses and small industry. On a larger scale, geothermal plants extract the heat from the earth and use it to create steam to power turbine engines.

*Wind turbines produce energy using the same principal as windmills. Blades are moved by the wind, and a shaft attached to the blades rotate a generator that produces energy. This energy is stored in batteries. Wind is, of course required to run this type of alternative energy, so the more wind you have the better it will work. Sites where there is a lot of wind, such as open farmland are good for wind turbines, or other locations that cannot be reached by powerlines.

*Biomass is organic material that can be converted to fuel. There are many types, such as animal waste, crops and grains, wood and other byproducts from mills and forests as well as from aquatic plants. One type uses the matter to burn to produce steam power; another type transforms the matter into a gas or liquid.

*Solar energy is probably the most well known form of alternate energy. It is the safe and efficient use of the heat from the sun to form energy.

*Energy from water. Hydroelectric energy is the energy produced by dams. The movement of the water causes turbines to generate power instantaneously. The initial cost of a dam is very high, but after that the power is free. Tidal energy works on the same concept as dams. The turbines are put directly in the water and the motion of the tides over them powers the turbines. Wave energy uses the motion of the waves in the same way.

As alternative energy research continues, more alternative energy sources will be found. Perhaps one day we will heat our homes by transforming our refuse into a usable source of energy.

There are many, many advantages to using LED lights as much as possible, especially when we want to save energy on our planet. The light created by LED light bulbs is much safer lighting than that of regular light bulbs – primarily because most light bulbs become very hot when used and can potentially cause fires. With LED lights you will never as much as burn your fingers touching a bulb, no matter how long it has been lit. However, LED lights can (and already do) serve a lot more purposes for the environment of which people are unaware.LED lights are usually, and most effectively, designed in colors as opposed to translucent lights. As a matter of fact, some of the very first LED lights were designed for Christmas decorations etc. This is because people wanted safer lights to be sure there were no unfortunate accidents occurring due to hot lights and dry pine needles or outdoor leaves and so on during the holiday season. However, research, design and technology have been updated and are continuously being considered for other reasons.

LED lights are already being used for more purposes than you may think – and we should focus on incorporating LED lighting into even more of the lighting we use. The following are examples of some ways in which LED lighting has already been utilized in our economy:

o Christmas lights, as I mentioned before are available as LED lights. They have become more and more popular since the cost of LED lights lessened around the year 2002.

o Exit signs, traffic lights, for example, have been used with LED technology as opposed to other forms of lighting.

o Flashlights, toys and other small devices are using LED lights for the benefit of a LED light’s ability to continue to work longer than a light with regular bulbs. In other words, batteries actually perform better and last longer in merchandise that uses LED light.

o Elevator push buttons.

o Status indicators: the status indicators on all kinds of equipment and technological merchandise have begun to use LED lighting.

o Motorcycles and bicycles already have LED lights for safer nighttime riding.

o Movement sensors.

o Glow lights.

o Thin lightweight displays at places such as subway stations, airports, trams, highway signs buses, and ferries have been using LED lighting for awhile. Nonetheless, I believe that we could use this option even more – LED lighting is a way to improve the environment, reduce electric risks, and eliminate the waste of energy.

o Light bars on emergency vehicles.

o Automotive high-mounted brake lights and truck and bus brake lights have begun to use LED lighting as well.

o Remote controls for stereos, DVD, television, and CD players often use infrared LED lights. It has actually been that way for some time now. People don’t often notice how often they have to change remote batteries – unless it seems like they have to be changed too frequently. Thus, you may not even notice that you own an LED remote until it finally does require a change of batteries. This happened to me and I realized how much more infrequently LED operated merchandise of all kinds allow batteries to last and last.

o Back lighting for LCD televisions and displays frequently uses LED technology.

o New theatrical stage lighting equipment is being created in LED lighting for primary red – green – blue arrangements.

LED lights are usually, and most effectively, designed in colors as opposed to translucent lights. However, these pale to darkly colored lights are quite effective for many purposes. The wonderful idea of LED lighting is one to grasp onto when we reach out for alternative sources of light and energy. Some of the very first LED lights were designed for Christmas decorations, but it does not stop there. LED lights can prevent unfortunate home fires occurring due to the heat generated by burning light bulbs, but are not nearly as inexpensive as we would like just yet. However, research, design and technology have been updated and ways to improve the expenses of LED for more and more purposes are continuously being considered. I hope and predict that in the future the LED modifications we make will certainly make up for the cost in the long run. Because of the ability of LED lighting to last longer than virtually all other forms of regular lighting and because of the safety issues involved, the goal is that LED lighting will become more and more useful as time goes on.
