When people think or energy sources, they mostly think of coal, natural gas and oil, these fuels have been the source of energy for a number of years. One problem however is that they are limited in supply and availability.

Estimates have shown that the currently available sources will only meet our current energy demands for about 50 to 70 years or so. In order to find alternative sources of energy the world has decided to pursue renewable energy sources. However even renewable energy sources have their advantages and disadvantages too.

The available renewable energy sources that we have include solar, hydro, wind, geothermal, ocean and biomass. The most common of these advantages is that they are clean energy sources and do not pollute the air. They also do not contribute to global warming or greenhouse effects. Because the sources of such energy are natural the cost of operations are substantially reduced and they require less maintenance on their plants. One common disadvantage is that it is impossible to produce large quantities of electricity than can be done with fossil fuels. Because they are new technologies the costs of initiating them is also high.

Solar energy utilizes the energy from the sun. It has its advantages because these systems can easily fit into existing buildings and do not affect land use. Since the area that these collectors rest in is quite large, a lot more materials are needed. Solar radiation is also controlled by geography too. It is also limited to the daytime as well as non-cloudy days.

Wind energy makes use of the power of the wind in order to create electricity. Though it produces the most jobs it is reliant on strong winds too. Wind turbines tend to be large and though the areas under them can be used for farming, most people think of them as unattractive looking. These turbines are also very noisy to operate and they threaten the population of wild birds too.

Hydroelectric energy makes use of water in order to produce power. It is the most reliable of all energy sources that are renewable. Its disadvantages are that it affects the ecology and causes downstream problems. Decay of vegetation on the riverbed can also cause a buildup of methane which contributes to the greenhouse effects. Dams may also cause an alteration of the natural river flow and affect wildlife in the area as well. Water which is colder and which is lacking in oxygen tends to be released into the water this kills the fish, sudden release of water like this may also result in flooding.

Geothermal energy makes use of the steam from the Earth’s ground in order to generate power. It uses a smaller land area that other types of power plants. They can literally run continuously throughout the year. The disadvantages tend to be that these plants are site specific and it can bring up toxic chemicals and heat from the earth when it tries to obtain the steam. Drilling such geothermal reservoirs can also cost a lot.

Biomass electricity is made from the energies of wood, agricultural and municipal waste. It tends to help save on landfill waste but the transportation is also expensive and tends to affect the diversity of the land. Other than this the process is quite complex and should be much simpler.

Ocean energy has proven to be a clean and abundant energy form. It tends to be expensive and in order to access this energy, you need at least a 40 degree Fahrenheit difference in water temperature throughout the year. Other than this, the construction and putting in place of pipes may damage the ecosystem.

Most of our energy comes from burning fossil fuels, this creates a lot of pollution. The other problem with fossil fuels is that they are quickly running out, some experts have suggested that within 50 years our supplies of fossil fuels will of run out. That would cause huge problems for generating power and running vehicles. One of the best alternative methods of generating power so far is solar power.

Solar power is so good because it’s reliable, clean and doesn’t cause any pollution. These panels collect sunlight and convert the suns energy into electricity. This sunlight can be used in a number of different situations, be it factories or homes. Solar panels are suitable for commercial and private use.

Reasons Why We Need Solar Energy

We have been dependant on fossil fuels for over a hundred years and few people have stopped to consider what it’s doing to the environment. As a result we are now experiencing global warming and pollution. It’s only now that renewable forms of energy are being sought, and this is simply because the reserves are running out. Solar power is one of the most popular forms of alternative energy.

The sun is very powerful, just so you understand how powerful it is the energy which is provided by the sun for a single hour is enough to power the world’s electricity for a whole year. The sun is a fantastic and powerful resource which won’t run out for a very long time to come. These renewable forms of energy are vital to the future of the modern generation.

Residential Uses Can Win Big with Solar Energy

Solar power isn’t just for commercial use, Private homes can benefit from using solar power. Homeowners can utilize their roofs to capture energy to convert into electricity. This means that you don’t have to use any extra land as you already have some space available that you’re not using.

My favorite part of installing solar power systems is that any excess power you’re not using can be sold back to your utility company. This will reduce your electricity bill even when you’re not using solar power.

There are many different exciting applications for solar power. They are commonly seen on street lights, school crossing lights, and even traffic control systems. It’s possible to power large gates and doors using solar power which saves the need to dig trenches and install cables.

Many developing countries have also benefited from using solar power as it can be difficult to get power to these locations. Lots of companies are working to make solar power an even more viable alternative to fossil fuels.
