Sources for renewable energy are all around us. When you say renewable energy the first things that always come to mind are wind and solar power. These two technologies have been the primary focus for discussions about renewable energy for quite some time. Complimented by geothermal energy and biomass production, these four get 99% of the attention when it comes to renewable energy sources. However there are many more potential sources for renewable energy sources in today’s world and it is going to take a broad approach utilizing multiple technologies to truly solve our current energy problems.

The big four sources of renewable energy have gotten the most media and government attention because they all at one point in time were thought to have the potential to be the silver bullet for the energy problem. They were all supposed to be THE solution to our growing demand for energy and dependence on foreign resources. However, it has become quite apparent that no one of these technologies alone can actually provide that kind cure all effect, thus it is time for us to take a broader look at the potential sources of renewable energy around us.

Anywhere there is motion; there is energy being spent and energy that can be captured. The goal of renewable energy sources are to find naturally occurring or wasteful sources of motion and harness this motion to create energy. This is precisely what wind turbines do, they harness the motion of the wind to turn a generator and make power. This same idea can be applied anywhere that here is naturally occurring motion. One example that has actually been tried with some success but needs further development is river turbines.

Of course hydro power has been around for a long time inside of dams, but the building of reservoirs and flooding of land is tremendously harmful to the natural environment. The river turbines of the future will simply harness the natural flow of a river to turn a generator. They will be similar to wind turbines, with blades that extend out into the river current. These turbines could be sunk into the bottom of deep sections of river and have no noticeable effects on the area around them. These river turbines however need to be incredibly durable and low maintenance, which is part of the reason they have only seen limited success and use thus far. However, with further development it is quite possible that they could become a very reliable source of renewable energy.

Another naturally occurring source of motion is the ocean. Ocean’s are constantly in motion, between wave action and tidal changes there is a lot of potential energy that would capture. There have been several different attempted technologies for capturing the motion of the ocean for energy purposes, but they have not received much attention. One major difficulty is the harshness of the environment in the ocean, which corrodes metals and is generally a treacherous environment. Again though, there is a huge potential for renewable energy in this as of yet unutilized source, it will simply take smart development of new technologies.

Turning to wasted potential from human endeavors the smoke pouring out of manufacturing facilities around the country is a prime example of wasted motion. There are several technologies in place and underdevelopment that take this motion of hot air up smokestacks and use it to generate electricity. You can think of it as a constant wind, as long as the factory is running, there will be air moving up the smoke stack, and if you had something in the smoke stack capturing that potential energy you could use those pollutants to help reduce the strain on the environment from power generation.

It is these kinds of creative solutions that, all put together, will be able to truly impact the way we generate power. No one source of renewable energy will ever provide the silver bullet everyone is looking for and it is time to give up the hunt. We need to invest in and pursue a broad spectrum of renewable technologies, not in the hopes of finding the best one that will solve all of our problems, but with the goal of getting all of them to the point where they can contribute to the overall solution. Simply looking at the world around us will show an untold number of potential renewable energy sources, all it takes is creativity and a commitment to pursue multiple technologies with the hope of developing a diversified renewable energy platform that can replace our current dependence on fossil fuels.

The key to our global energy necessities in the time to come is Renewable Energy. Nowadays we are loosing our supply of uranium and fossil fuels. Not only we are running out of these energy stocks but the costs rises constantly for economic or political reasons. The prices of renewable energy stocks can turn much more competitive. Utilizing the latest technologies, most ocean energy is not cost-effective likened to other renewable energy stocks still the ocean persists as one of the big potential energy reservoir for the time to come. Renewable and non-renewable energy reservoirs are both applied to generate electrical energy, power vehicles, and provide heating, cooling, and light.

Numerous people don’t know how renewable energy is made but in point of fact it’s not that difficult to understand. Renewable Energy is energy which established from resources that are regenerative or renewable. This means that they cannot be depleted. These resources are healthy for our surroundings and create energy without the bad smuttiness and emissions tied in with fossil-fuels.

While this industry spreads out, the expertness of these support industries is being exploited to allow the support and infrastructure required for the progress of renewable energy production globally. Multinational companies are looking for green or renewable resource technologies and companies to invest in, fund, acquire, license or strategically partner with. This is the cause for the giant growth. Renewable energy systems embrace a enormous, several array of technologies, and the present-day status of these can vary considerably. Some technologies are already developed and economically competitive.

All over the world we recognize that utilizing inexhaustible resources has the potential to supply us with fresher air, a more diverse energy portfolio, and less dependence on foreign fossil fuels. Presently renewable resources scores for just 3.4 percent of total global power generation. The International Energy Agency recently published a news report forecasting that in order to cut down greenhouse gas emissions 50% by 2050, global investment funds in renewable energy, energy efficiency and carbon sequestration will need to reach roughly US $45 trillion dollars by that date.

They are bearing that 60% of all our energy will come from renewable resources by the year 2070. But the sooner we stick with the attitude that today is better than tomorrow, the bigger the chance to increase this figure to 80%.

Renewable energy is sustainable energy that comes from the natural surroundings. Renewable energy or also known as Green Power, is power that comes from renewable resources such as the sunlight, wind, hydro-electric dams and organic matter (biomass). These resources are incessantly replenished by nature and are a healthier source of energy.

With people looking for more and more ways to find renewable energy sources, many don’t realize they are standing on top of one of the greatest energy resources on the planet. The Earth’s core is at an unbearable temperature, hotter than anyone could possibly even fathom. This heat builds up so much pressure in the Earth’s core that it has to be released in some way. These releases are known as geothermal energy. The hot water and steam from the Earth can be used in a number of ways to create energy. This is a renewable energy because the heat in the Earth’s core is constant and the water replenishes from rainfall.

There are different ways to use geothermal energy that include direct and indirect uses.

- The heat from the Earth could be used as a direct source for heating systems. The hot water close to the Earth’s system is directly pumped into heating systems.

- Generators in power plants require steam at very high temperatures to work. Geothermal power plants are built near reservoirs to tap the natural resource. The power plants use steam or water close to the surface to operate its generator.

- Geothermal heat pumps use water near the Earth’s surface to control building temperatures. This renewable energy source can regulate entire towns and villages.

Using geothermal energy isn’t a new concept. History has shown that people in ancient times have used hot springs for cooking, bathing and heating purposes. Even today many believe that natural hot springs have healing powers. There are many people who still bathe in hot springs. In Reykjavik, Iceland 95 percent of the buildings are heated with geothermal district heating systems. Hot water near the Earth’s surface is pumped directly into the buildings.

The Unites States is one of the leaders in geothermal power. The country has more geothermal power plants than any other, however, it only accounts for one percent of the electricity produced in the U.S. California (33), Nevada (15), Hawaii (1) and Utah (1) are the only states with geothermal power plants.

There are opponents of geothermal energy. While there are uses for it, criticisms have been raised. Some believe this is not a long term solution nor could it be used in huge environments. There are others who think creating geothermal power plants would cost too much money and drain money from researching other valuable energy resources. People are also concerned that if magma is tapped, it could bring up dangerous and harmful particles.

One thing is certain, more research is needed to make an educated conclusion about geothermal energy. There is too much guessing going on and not enough doing. There are results of natural geothermal reactions. These happen everywhere and come in the form of volcanoes, hot springs and geysers. With geothermal reactions occurring naturally, humans should find a safe way to tap into it.
