The Definition of Renewable Energy – Present and Future Outlooks

The definition of renewable energy is dependent on the term renewable. An energy source that naturally replenishes is considered renewable. Unlike fossil fuels which take millions of years to form, wind, rain, water and sunlight are self contained and naturally replenishing, thus renewable.

Many people think solar energy, the most popular form of renewable energy, is a new concept. The truth is solar panels were used as far back as the 1920s to heat water in lieu of more expensive electrical heating systems.

Renewable Energy Past to Present

When fossil fuels were unearthed, much of the previous solar energy use was abandoned for the cheaper, more reliable fossil fuels. As these fuels began to have an impact on the environment and their levels diminished, a resurgence of the renewable energy sources occurred.

Today, wind farms, solar electrical plants and solar thermal plants are used to power entire towns and cities.

Alternative energy communities are also popping up throughout the world with Canada being the first country to boast of an entire community based on solar energy. Technology is constantly changing and the future definition of renewable energy is also changing.

The Future of Renewable Energy

Everything that moves creates energy. This fact applies to wind, water and sunlight which are the most commonly used renewable energy sources. However, the movement of man is also being viewed as a source of renewable energy.

Speed bumps that harvest kinetic energy are one concept currently being tested by New Energy Technologies. The “bumps” are actually an inversion of the typical motion inhibitors. These flat panels sink slightly into the ground when a car passes over. The bump is created by the difference in height between the road and the lowered panel.

Under the panel, 2000 watts of instant energy is created for every passing car. With 1000 cars passing over the speed bump every day, 2,000,000 watts or 2000 kilowatts are produced every day.

Over the course of a month, that number jumps to 60,000 kilowatts. That is enough electricity to power 60 average homes for an entire month!

This type of kinetic energy harvesting is not limited to speed bumps. In Israel, roadways are being tested that collect small amounts of energy as cars pass over the special roadway surface.

The amount of energy is small, at an average of 400 kilowatts per kilometer (0.6 miles). While this does not seem like a lot of energy, if the entire United States interstate system were converted to kinetic energy harvesting material, the 75,000 km would produce 30,000,000 kilowatts of power. That is one very new and innovative definition of renewable energy!

The world is just beginning to see the potential kinetic energy has as a renewable source of electricity. Tokyo is installing flooring that harvests energy from daily subway visitors. Dance clubs are utilizing the energy created from movement on the floor to harvest energy.

Even asphalt is being considered as a prime material for harvesting thermal energy in desert climates where roadways can reach temperatures hot enough to fry an egg.

There are an abundant supply of new and innovative renewable energy solutions available to help us to transition our world to more sustainable and environmentally friendly solutions. Even today there are many new technologies that can help us to heat our homes, recharge our batteries and light our yards using clean, green energy sources.

What You Should Know About Green Electricity

Green electricity is a kind of electricity which produces no harmful effects on the environment. Different sources of green electricity are also known as renewable energy sources because there supply never runs out.

Nowadays, it is very evident that the problems regarding electricity sources and its substantial impact to the environment are very rampant. Moreover, the cost of electricity consumption is indeed growing up causing families to have a hard time paying their electricity bills and the like. With this, several guidelines on the process of greening the electricity and its use are already being promoted. Here are a few tips on how to go green with your electricity.

Essential tips supporting green electricity:

Signing up for green power
What does green electricity means? Green electricity is a kind of electricity which produces no harmful effects on the environment. Common sources of green electricity are hydroelectricity, geothermal, wind power, wave technology, solar power and many more. Hydroelectricity converts water energy into electricity. It is considered as the longest lived source of green electricity as well as the cleanest method in terms of its production. On the other hand, geothermal is another type of source which is known to produce green electricity. It utilizes the heat from below the earth’s surface and therefore captures steam which will then be converted to electricity. You can also generate electricity from wind by making use of wind power as one of its source. Moreover, oceans can also contribute as a source of green electricity through the process of wave technology. Above all, there is solar power which utilizes energy coming from the sun. It is still referred as the most common and preferred source of green electricity.

These are also known as renewable energy sources because there supply never runs out. These sources utilize the natural energy flows of the earth reason why green electricity is very advantageous to the environment.
It is indeed recommended to sign up for green power and make use of green electricity. In this type of program, private organizations buy renewable sources of energy and pass it on customers. It is quite expensive than the conventional electricity suppliers but it promotes clean and good effects to the environment.

There are also online websites which lets customers buy renewable energy credits. These are websites which will calculate a family’s energy consumption and buy a certain amount of renewable energy credits to compensate for it.

Conduct home energy audit
Home electronic energy audit is a process wherein you conduct an inventory on where the energy in your home is being used, where energy is being lost and most importantly where can it be saved.  You can personally conduct your home energy audit and there are also organizations which offer services regarding home electronic energy audit.

Reduce electricity consumption
It is very easy to reduce electricity consumption in the house. Each family member can participate by unplugging appliances which are not being utilized. You can also turn off appliances when they are not needed. Instead of using the air conditioning, you can make use of electric fans as the best alternative. In these simple ways, less important electricity consumption can be eliminated.

Buying energy efficient appliances
Every family needs to bear in mind that if they are planning to buy electronic appliances, they should consider those brands which are energy efficient. In line with this, there are LED television brands which are already released in the market. They are known to produce less electricity consumption rather than the conventional television brands. Aside from this, there are also electronic solar chargers which are energy efficient for different appliances such as laptop, cellular phone, camera and even Mp3 players.

Above all, it is very important to assess your own electricity consumption and support campaigns and initiatives on how to go green and help the planet. Thus it is indeed beneficial to support green electricity by considering green power.
