Technology has shown that it's possible to harness the energy of the sun in a clean and sustainable way. Costs to go solar have continued to decrease as technology improves and solar power gains traction ... however, cheap, sustainable solar power is still a few decades away from making it into our every day lifestyles.
The goal is to create energy systems that are pollution-free, abundant and capable of providing enough power to meet demand. All other power sources (i.e. hydro, coal-fired and nuclear) meet some of these criteria but have serious problems that are not factored into the price. Hydro causes environmental degradation on the local watershed; coal-fired power plants give off carbon-dioxide; and nuclear waste sits around waiting for a future solution. In contrast, solar power:
Sustainable solar power is available today, but it is certainly not the cheapest available energy source. Subsidies are required to compete against other power sources whose true cost is hidden. When factoring in the cost of pollution and environmental degradation of the other sources, the economics of solar power look more promising (not to mention the many benefits! - click here to get a free quote for solar in your area).
In order for solar power to make a larger impact, it needs to overcome some technical and economic hurdles:
Cheap, sustainable solar power would provide energy to future generations while reducing the impact of pollution, toxic waste and environmental problems from other energy sources.
