Answers
Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.[1][2]
It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light-dispersing properties, and designing spaces that naturally circulate air.
The large magnitude of solar energy available makes it a highly appealing source of electricity.
Its uses:-
--As heat for making hot water, heating buildings, and cooking
--To generate electricity with solar cells or heat engines
--To take the salt away from sea water.
--To use sun rays for drying clothes and towels.
--It is used by plants for the process of photosynthesis.
(Effective steps to Conserve The energy)
1. Unplug Your Appliances
Turning off home appliances is not the “energy saver” you might think it is. Many modern electronics use stand-by power when not in use — from TVs to computers to telephone charges. This unused “phantom” power accounts for 75% of the electricity that home appliances consume. So when you’re done charging your phone or watching TV, it’s best to unplug completely.
2. Use Energy Efficient Appliances
EPA-approved EnergyStar appliances use between 10% and 50% less electricity than traditional home appliances. Although they carry higher upfront costs, Energy Star appliances quickly pay for themselves when you factor in your lower monthly electricity bills.
3. Use Compact Florescent Light Bulbs
CFL light bulbs use 75% less electricity than their incandescent counterparts. They also last 10 times longer. Like Energy Star appliances, CFL light bulbs cost more upfront, but the financial payback is 100% worth it.
4. Plug Leaks in Windows, Crawl Spaces, and Doorways
Did you know that more than 50% of your home’s energy consumption goes to cooling and heating? If your home is not properly sealed, this means your thermostat is literally regulating the temperature of the entire world — and you’re paying for it. Be sure to plug all leaks — including around windows, doors, vents, and any other entrances into your home.
5. Insulate Your Home Properly
Similar to the point above, insulating your home is one of the best ways to make sure your AC units and furnace aren’t working overtime.
