What is the potential of solar energy?
The world’s overall solar energy resource potential is around 5.6 gigajoules (GJ) (1.6 megawatt-hours (MWh)) per square metre per year. The highest solar resource potential is in the Red Sea area, including Egypt and Saudi Arabia.
Does solar energy have a future?
Given that it is readily available and renewable, solar power is an attractive source of energy. … However, as of 2018, less than two percent of the world’s energy came from solar. Historically, solar energy harvesting has been expensive and relatively inefficient.
Why solar energy is important for future?
It is the most important source of energy for life forms. It is a renewable source of energy unlike non-renewable sources such as fossil fuels. … It is therefore important to go for reliable, cost effective and everlasting renewable energy source for energy demand arising in future.
How do you build solar energy?
Solar-powered photovoltaic (PV) panels convert the sun’s rays into electricity by exciting electrons in silicon cells using the photons of light from the sun. This electricity can then be used to supply renewable energy to your home or business.
