In an era with an emphasis on protecting the environment, the race for finding reliable and feasible renewable energy sources continues. We all know the disadvantages associated with relying on non-renewable energy sources such as fossil fuels, such as the costs and the hazards they pose to the environment. However, as technology continues to improve year after year, utilizing solar energy as a reliable source of energy for every day applications is becoming more of a reality. Solar energy is one of the main sources of energy for every life form, and approximately 120,000 terawatts of solar energy hits the surface of the earth each day.
Utilizing solar energy for everyday applications is the perfect form of renewable energy. Why is solar energy renewable? Solar energy is a natural energy source, and because so much solar energy hits the earth’s surface each day, harnessing the energy of the sun does not require the burning of fossil fuels, and doesn’t create the associated air emissions. In fact, one of the main advantages for solar energy is that it causes no harm to the environment. However, in the past, utilizing solar energy for every day purposes such as solar power for your home hasn’t historically been a feasible option. Although some residential and commercial buildings utilized solar energy as early as the 1980s, residential solar panel systems technology was in its early stages and far too expensive for the average homeowner or business to afford. Today, solar energy technology is improving significantly, allowing manufacturing costs to decline, and allowing both commercial and residential solar energy systems to be more affordable and obtainable as a source of renewable energy.
Solar energy technology continues to improve. Currently the best achieved sunlight conversion rate (solar panel efficiency) is around 21%, nearly a 10% improvement from where it was just 10 years ago. With the cost of solar power projected to reach just $1 per watt by the year 2020, the many advantages for solar energy make solar power for your home or business an intriguing option in the near future. As technology for solar energy systems continues to improve, perhaps solar energy will be a feasible option for more applications, such as transportation. Read more.
