Solar Energy: The Energy of the Future
Our Earth's resorvoir of resources seem to be limitless, but with the exponential growth of the human population; the need for efficient alternative energy sources is becoming urgent. Therefore, research companies and individuals are focusing on creating new energy systems. Fossil fuels are are depleting and becoming more difficult to obtain. The earth will face an energy crisis in the near future if humans are not careful with their consumption. To avoid this disaster it is vital for us to utilize alternative sources of energy to its full potential. Widely used fossil fuels like coal, oil, and petroleum are very harmful to the environment. The earth is warming up, the climate is changing, and the ozone layer is gradually thinning, largely due to the effects of fossil fuels. Although fossil fuels are currently the main source of energy; solar energy may one day replace fossil fuels in the future.
Fossil fuels do not self-sustain naturally at a fast enough pace, to match society's high energy demands. Resources are diminishing quicker than the Earth can replenish them. Unlike renewable energy sources, most of which are converted to power cleanly, the conversion of fossil fuels to energy harms the environment. Processing fossil fuels emit harmful greenhouse gases, primarily carbon dioxide, methane, and nitrous oxide, into the air. Thus, polluting the air, creating respiratory health issues and also thinning the ozone layer which protects the population from the sun's radiation and the air pollution also affects our respiratory health. "The National Research Council, an agency of
Li, 2 the Governement of Canada which conducts scientific research and development, explored the external costs of energy, costs that are not factored into its market price. Requested by Congress in the Energy Policy Act of 2005, the report revealed that there are substantial “hidden” costs to our energy production and use,
