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.

As you know, sources of energy like solar energy, wind energy,.. are very important. People use them for many things:cooking, heating,ect...But, almost the sources of energy have the disadvantages and advantages. There are two kinds of energy:non-renewable and renewable energy. Non-renewable is very popular in many countries. They are abundant, available and easy to use. However, they won't last forever and they're harmful for the environment. And, people will use renewable energy to solve the problems of non-renewable energy. Renewable sources of energy are forever and they're clean and safe, too. Nevertheless, they have some problems, too. For example, nuclear is clean but it's dangerous to use. Wind power has many advantages but it isn't available,... On the other hand, there are some sources of energy don't have some serious problems like solar energy. It's the reason why people use solar energy in the future. So, what should we do to save energy? We should use them properly and use them less. We should use less cars or motorbike, too. It also have the enviroment. Energy is very important, we should protect them for our life in the future.

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

Hello students. Today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills....

Hello students. Today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.

The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

Non-renewable energy is the energy taken from other sources that are available on earth. They are limited and will run out in the future. They can't be re-generated in a short time. Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.

Question 2: There is a large amount of non-renewable energy.

A. True

B. False

C. Not Given
