A Few Words about Solar Energy

You have probably heard it all before; that one day, we will be able to use all renewable resources and cut ourselves loose from the stranglehold of foreign oil and fossil fuels. You have probably heard it so many times that you may have stopped believing it. Have you ever really stopped to think about it though? Each and every day, most consumers use a great deal of energy.

They use electric power to light their houses, gas power to cook their food and run their cars, as well as a long list of other non-renewable energy sources. You may not think that you use that much, but even multiplying your usage by a few billion is still a great deal of energy used each day.

When you remember that sources such as fossil fuels are not easily or quickly renewed, then you can begin to see that we may not be far away from big trouble.

Not only are we in danger of running out of these resources, but the processes used to collect them and refine them is costly to the consumer, and even more costly to the environment. Even now, areas are being stripped of their natural resources and polluted with chemicals.

Animals are seeing their habitats destroyed to either gather resources, or make room for more power plants and companies to process them. Our only answer; our only way out of this is to search for renewable sources of energy that we can harness safely and effectively.

Luckily, we do not have to look far to find them. Take the sun; it comes up each and every day beaming rays of warmth and light down upon us. What we have wasted for so many years has now been found to be a valuable source of energy. Not only are solar panels a great addition to millions of homes today, but there are other solar powered items in the works, such as the solar powered car.

There are even giant solar panels made to catch the moonlight as well, and harness it into useable energy.

Unfortunately, we have not yet found a way to harness enough solar energy to make ourselves completely independent of the power companies, but we should all remember that every little bit helps. Even cutting half your power bill through the use of solar powered energy can make a difference of several hundred dollars each year.

Renewable Energy: Wind Power and Water Power

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable.

The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance ofnon-renewable energy sources, such as nuclear fuels, these energy sources are depleting.

In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.

While there are many different types of renewable energy sources, wind power and water power are two of the most popular, only surmounted by solar power.

The use of wind power and water power is popular because they are actively found throughout the world and readily available for use.

Wind power is a commonly used renewable energy. Wind power produces no methane or other greenhouse gasses while in operations, which makes it a popular source of renewable power.

Wind can be used to operate wind turbines, which are especially very popular in the commercial arena. The main issue with wind is that it is not constant, thus it tends to be less energy producing than solar power.

In addition to consistency, wind turbine farms generally require significant space for construction and operation. Even though it is not as popular or as efficient as solar power, wind power is believed to be able to produce more than five times the amount of global energy used.

Water power is the use of energy located in water as a renewable energy source. From large oceans and rivers to a small brook or stream, significant amounts renewable energy can be collected and used from all type of moving bodies of water.

Types of water energy that are being used today include hydroelectric energy, damless hydro systems, ocean energy, tidal power, wave power, and deep lake water cooling, just to name a few. As water is a part of the entire world, advancements have been made and developments continue to try to better enhance the understanding and usage of water energy.

Renewable energy is a very important topic for the future survival of the planet Earth. It is important that the world works together in order to share discoveries and research, especially regarding how to reduce the use of non-renewable resources and lowering the cost of renewable resource technology.
