Homemade Solar Cell

Our thirst for oil and other fossil fuels has brought us to the point where we are doing irreversible harm to our planet. We are also quickly realizing that we are running out of these non renewable resources. As the global economy continues to grow, a world fueled by green power is not far off.

As various green technologies continue to be developed, a few of them are already showing promise as serious contenders.

A wide range of new and green technologies are gaining momentum as they are being introduced into our power supplies.

One of the most cost effective ways of producing electricity is through the creation of wind farms. Windmills have been sources of power for hundreds of years, but only recently have they been seen as a reliable and stable source of power. Only three percent of the world’s power is supplied by wind turbines, but that number is growing exponentially as people discover how green this power source really is.

As long as there is wind, they can generate a lot of electricity. They are relatively inexpensive to build and require very little maintenance once in operation. Wind turbines have very low emissions and they can provide a steady source of clean energy for a long period of time.

On the subject of turbines, another trend emerging is building sea turbines that capture the energy of water currents to generate power. This technology is being used in small scale situations all over the globe, and they are also generating power with no emissions. They are a little more complex than wind turbines, and they require more maintenance due to the corrosive nature of salt water.

Solar power is getting popular again, and on large scale projects as well. The western United States has quite of large solar farms which are making electricity every time the sun shines. Solar power has tremendous potential as a renewable energy source, however they are not cheap to build and maintain. Until these costs go down, it is not practical to use it as a source for our power needs.

Coal and natural gas are both huge sources of energy, but they are in limited supply. An alternative to natural gas is methane, which is found in landfills as well as in pockets under the oceans all over the world. Clean burning and efficient, methane is showing great promise, but the technology is not available yet to harvest this resource.

Green power has exploded into the world stage in the recent past, and it will continue to become more and more integrated into our power hungry lives. More research will reveal how these technologies can be adapted to satisfy our ever increasing hunger for power.
