What are the uses of energy sources?

When we talk about residential uses of energy, these are the most basic uses of energy. They include watching television, washing clothes, heating and lighting the home, taking a shower, working from home on your laptop or computer, running appliances and cooking.

What is the source of solar energy?

Solar power is energy from the sun that is converted into thermal or electrical energy. Solar energy is the cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world.

What is solar energy example?

It is energy derived from the sun. Renewable energy technologies such as solar cells and solar panels are used to harness the sun’s energy to provide light, heat, hot water and generation of electricity for homes, businesses, and industries. Solar energy can now also be used to fly planes.

What are the 4 sources of energy?

There are five major renewable energy sources

  • Solar energy from the sun.
  • Geothermal energy from heat inside the earth.
  • Wind energy.
  • Biomass from plants.
  • Hydropower from flowing water.

What is one disadvantage of using solar energy?

High initial costs for material and installation and long ROI (however, with the reduction in cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet. No solar power at night so there is a need for a large battery bank.
