Renewable and Nonrenewable Energy

Energy can have many forms such as kinetic, potential, light, sound, gravitational,

elastic, electromagnetic or nuclear. According to the law of conservation of energy, any form

of energy can be converted into another form and the total energy will remain the same. For

example, a labourer when pushes the pile of bags, his potential energy stored inside him is

converted into the kinetic energy from the movement of matter or when you burn the wood

it's chemical energy is converted into the heat energy or when you change your mobile

phone the electrical energy is converted into the chemical energy which gets stored inside

the battery's molecules.

Energy is broadly classifies into two main groups, renewable and Non-renewable.Renewable energy is energy which is generated from natural sources like sun, wind, rain,

tides and can be generated again and again as and when required. They are available in

plenty and by far most the cleanest sources of energy available on this planet. For instance,

energy that we receive from the sun can be used to generate electricity. Similarly, energy

from wind, geothermal, biomass from plants, tides can be used this form of energy to

another form.

Besides that, here are some of the pros and cons of using renewable sources of energy.

Firstly, the pros is the sun, wind, geothermal, ocean energy are available in the abundant

quantity and free to use but the non-renewable sources of energy that we are using are

limited and are bound to expire one day. However, renewable sources have low carbon

emissions; therefore they are considered as green and environment friendly. Renewable also

helps in stimulating the economy and creating job opportunities. The money that is used to

build these plants can provide jobs of people.

You don't have to rely on any third country for the supply of renewable sources as in

case of non-renewable sources. Renewable sources can cost less than consuming the local

electrical supply. In the long run, the prices of electricity are expected to soar since they are

based on the prices of crude oil, so renewable sources can cut your electricity bills. Various

tax incentives in the form of tax waivers, credit deductions are available for individuals and

businesses who want to go green.

In addition, there are some cons. First of all, it is not easy to set up a plant as the initial

costs are quite steep. Solar energy can be used during the day time and not during night or

rainy season. Geothermal energy which can be used to generate electricity has side effects

too. It also can bring toxic chemicals beneath the earth surface onto the top and can createenvironmental changes.

Hydroelectric provide pure form of energy but building dams across the river which is

quite expensive can affect natural flow and affect wildlife. Next when you use wind energy,

you have to rely on strong winds therefore you have to choose suitable site to operate them.

Also, they can affect bird population as they are quite high.

Renewable energy is energy which is taken from the sources that are available on the

earth in limited quantity and will vanish fifty-sixty years from now but Non-renewable

sources are not environmental friendly and can have serious effect on our health. They are

called non-renewable because they can be re-generated within a short span of time. Non-

renewable sources exist in the form of fossil fuels, natural gas, oil and coal.

Here are some of the pros and cons of using non-renewable sources of energy. The first

pros is non-renewable sources are cheap and easy to use. You can easily fill up your car tank

and power your motor vehicle. Next, you can use small amount of nuclear energy to produce

large amount of power. Non-renewable also have little or no competition at all. For example

if you are driving a battery driven car your battery gets discharged then you won't be able to

charge it in the middle if the road rather it is easy to find a gas pumping station. They are

considered as cheap when converting from one type of energy to another.

To sum up the point, here have some cons for non-renewable. There are non-renewable

sources will expire some day and we have to us our endangered resources to create more

non-renewable sources of energy. The speed at which such resources are being utilized can

have serious environmental changes. Non-renewable sources also release toxic gases in the

air when burnt which are the major cause for global warming. Since these sources are going

to expire soon, prices of these sources are soaring day by day.

In other word, energy needs to be conserved to protect our environment from drastic

changes, to save the depleting resources for our future generations. The rate at which the

energy is being produced and consumed can damage our world in many ways. In other

words, it helps us to save the environment. We can reduce those impacts by consuming less

energy. The cost of energy is rising every year. It is important for us to realize how energy is

useful to us and how can we avoid it getting wasted.

In a nutshell, to start saving energy is not a big thing at all. We can start saving the energy

from our home itself, just by turning off the lights during day hours, washing clothes in cold

water or using public transport instead of using our own vehicle and later can implement

these things on much wider scale at society level, then at city level then district level and

finally at country level.
