What Are Solar Power Generating Systems?
Solar power generating systems absorb sunlight and convert it into electricity that we can use. Every second, the sun sends about 42 trillion kilocalories of energy to the Earth. If we could convert 100% of this solar energy into electricity, we could create one year’s worth of power for the entire planet in a single hour. Solar energy is the most powerful of all renewable energy resources.
The Earth’s reserves of fossil fuels, such as petroleum and coal, may eventually be depleted. Moreover, burning these fossil fuels creates carbon dioxide emissions, which are contributors to climate change.
In contrast, as long as the sun exists, we can harness its energy here on Earth; and because solar power emits no carbon dioxide, it is an effective solution to natural resource depletion and climate change — problems that are becoming more serious every year.
