Solar Energy

The Economic Impacts of Solar Energy

The Main power source

As a source of energy, nothing matches the sun. It out-powers anything that human technology could ever produce.The sun is the star in the center of the solar system.It is a perfect spherical and is made up of of hot plasma with magnetic fields.We have been using the energy it produces for millions of years in the most efficient ways and one of those ways is converting the energy it produces into solar energy which we then use to cook food,power our homes,heat food,power electronics,etc.

How is Solar Energy transferred into electricity that we use at our homes ?

1) The Sun provides the solar panels with the energy also known as the sun rays or the sunlight.

2) The solar cells then transform the provided sun rays into electricity used to power homes.

3) The transformed electricity then travel into a inverter.

4) The inverter then sends out the electricity to power companies like Hydro-one.

5) Then Hydro-one sends the electricity to local homes.

Energy 101: Solar Power

Enviromental and Economic Impacts

Solar Energy has a positive effect not only in the solar economy, but the national economy too.The first and the most obvious impacts is that it reduces the use of harmful resources like burning coal,oil and fossil fuels that pollute the environment which can cause harmful effects like acid rain and global warming.Now there are also some negative effects of using solar energy and one of them is the amount of land being used to build solar power plants.In order to make a power plant trees and forests are being cut down and that can make many animals homeless and destroy their habitats.

Advantages of Solar Energy

-It is a renewable source meaning that it can be used over and over again.

-Very little maintenance required.

-Does not create any sound or noise.

-Average solar panel has a lifetime of more than 40 years.

-They might seem expensive to buy for the first time but it decreases your electricity bill by thousands of dollars.

-Powers the house for many hours.

-Does not pollute the air so it does not cause harmful effects like global warming and acid rain.

-The power source of the sun is absolutely free.

-The production of solar energy produces no pollution.

-Most systems do not require any maintenance during their lifespan, which means you never have to put money into them.

-Most systems carry a full warranty for 20 to 30 years or more.

-No carbon footprint.

Disadvantages of Solar energy

-Solar panels require quite area for installation to achieve a good level of efficiency.

-The efficiency of the system also relies on the location .

-They are very expensive.

-In order to make a solar power plant trees and forests will be required to cut down.

-It only produces energy when the sun is shining or when the weather is nice.

-They cannot harness any energy during a storm,cloudy days or at night.

-In order to install solar panels on a regular town house it will cost you a minimum of $15,000.

-The total amount of solar energy consumed for human use is less than 1% of the entire energy requirements.

Interesting Facts about Solar Energy

-Solar energy is collected from sunlight.

-Solar cells convert light energy into electricity.

-Solar cells are also called photo voltaic cells.

-Solar energy is measured in kilowatts.

-Large numbers of solar cells are put together to create solar panels.

-Solar panels first appeared on the market in 1956.

-Solar energy is a very good back-up plan in case any other non-renewable sources run out like fossil fuels and coals.

-Solar panels are made up of silicon.

- One kilowatt equals 1,000 watts.

-Sunny areas like Los Angeles, California,U.S.A receive about 5.5 hours of sunlight per day.

-Cloudy areas like Hamburg and Germany only receive about 2.5 hours of sunlight per day.


For my final conclusion I would like to say that solar energy is a very positive source with little or no disadvantages.It has lot of potential in the future.
