Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.

Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency.

There are two kinds of energy in our life. They are renewable and non-renewable sources of energy. The non-renewable energy sources include oil,coal,natural gas,... The renewable energy sources include wind, solar, biogas, hydro,... Therefore, we should use more renewable energy than non-renewable ones in the future, because the non-renewable energy sources produce a lot of carbon dioxide. That's bad for the environment, and these energy sources are going to run out soon. The renewable energy sources are abundant, cheap, clean and they're eco-friendly. They will last forever.

Renewable energy comes from a source that will not deplete. Two common examples of this type of energy are solar power and wind power. Geothermal power, hydropower, biomass, and tidal power are additional forms of renewable energy that produce power for our planet right now.

The primary advantage of renewable energy is that fewer potentially harmful emissions are released into the atmosphere. Although fossil fuels are used to create the products that allow for this power to be produced, most forms of renewable energy can become carbon neutral in 5 years or less.

The disadvantage of renewable energy is that it can be costly. Although wind power and solar power have become cost-competitive with coal-fired power and nuclear power in some communities, some forms are not cost-competitive globally yet when the cost per kilowatt hour is compared. In 2015, the lifetime cost per kilowatt hour of conventional coal was 9.5 cents, while the cost of offshore wind was 15.8 cents.

There are additional advantages and disadvantages of renewable energy to consider as well.

Renewable energy describes a collection of energy technologies i.e. solar, wind, geothermal derived from sources that are never-ending and can be replenished time after time. Most countries across the world heavily depend on fossil fuels (oil, coal andnatural gas) as sources of energy to power their economies.

Fossil fuels are non-renewable forms of energy, meaning, they utilize limited resources that will ultimately deplete, hence, driving up overall energy costs. These very countries have responded to the threat by stepping up campaigns to embrace renewable forms of energy like solar and wind

I often go shopping at the open-air market near my house. However, there are some things I don’t like about it. First, it is outdoor. On rainy or hot days, it is uncomfortable to shop. Secondly, the sellers usually ask for a higher price than the value of the goods and you have to bargain. It’s not easy if you don’t know the actual price of an item. Another disadvantage is hygiene. Fresh products like vegetables are often not very clean.
