When you consider which natural forces can be used to power the world, the sun and the wind come to mind. In fact, the sun works to create the wind, so it goes without saying that our yellow orb or burning gas is the key to making the dream of energy independence an actual reality. And although there have been many advancements throughout the years, the technology needed to harness the sun’s power and deliver it to the masses doesn’t exist yet. But there have been some advances in the field.

Recently, at Ohio State University, researchers developed Dye Sensitive Solar Cells that are cost effective and turn more of the sun’s energy into useable electricity. Another milestone of solar energy came with the advent of the Heliotube. This solar panel capitalizes on the position of the sun relative to the position of the panel, allowing for maximum light exposure. There have also been paint-on solar cells that conduct electricity, and reflective dishes that have cut back on the demand for the silicon previously needed to construct solar panels.

Advances in wind turbine technology have also been numerous. Some areas in prime jet stream locations, such as Chicago, have greatly benefited from advanced wind turbines. The turbines are becoming smaller, and possess the capability to convert more wind energy into electricity through less wind force. And in Florida, scientists wish to use currents from the sea floor to power generators and provide air conditioning to homes for little cost.

The technology is growing; however, it isn’t moving along quickly enough to keep up with our insatiable consumption of electricity. Only a handful of people around the world are dedicating their time to give the world free, clean and renewable energy. This fight needs many more participants, for the enemy is all-consuming.
