Our Future about clean Energy

Dreams are renewable. No matter what our age or condition, there are still

untapped possibilities within us and new beauty waiting to be born.

- Dale Turner

It is clear like a crystal that clean energy is our dream what we want to achieve in

our future. We think about anything than we work on it and finally we get. Dreamsabout bright things give us courage, determination and devotion to work forconverting our imagination and thoughts in reality. It is useless to say that clean

energy is just a dream which is out of reach. Most people in world believe that onewho believes in clean energy in future is just like a person who is living in a

paradise of fools. But facts are opposite to this above argument. Nowadays worldis crazy about clean environment and every country of the world is trying its best

to use clean energy to save earth and make life safe. No doubt clean energy isexpensive and difficult to generate it but man cannot deny the advantages of using

clean energy.

In Act The Clean Energy Standard Act Of 2012" Clean energy is defined to

mean:

electricity generated at a facility placed in service after 1991 using

renewable energy, qualified renewable biomass, natural gas, hydropower,nuclear power, or qualified waste-to-energy; and

electricity generated at a facility placed in service after enactment that uses

qualified combined heat and power (CHP), generates electricity with acarbon-intensity lower than 0.82 metric tons per megawatt-hour (the

equivalent of new supercritical coal), or as a result of qualified efficiencyimprovements or capacity additions at existing nuclear or hydropower

facilities.

electricity generated at a facility that captures and stores its carbon dioxide

emissions

The term natural gas includes coal mine methane.

Qualified combined heat and power must generate at least 20% of its

useful energy as electricity and 20% as heat, and have an overall system

efficiency of greater than 50%. To be considered qualified renewable biomass, the biomass must be

produced and harvested in an ecologically sustainable manner.

Qualified waste-to-energy is defined to mean energy produced from thecombustion of post-recycled municipal solid waste, animal waste or animal

by products, biogas, landfill methane, or other biomass that has been

diverted from or separated from other waste out of a municipal waste

stream. Existing waste-to-energy facilities must be in compliance with allapplicable environmental regulations for new facilities within the

applicable source category under the Clean Air Act.

Renewable energy is energy which is generated from natural sources i.e. 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 thisplanet. For e.g.: 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

Non-Renewable energy is energy which is taken from the sources that are availableon the earth in limited quantity and will vanish fifty-sixty years from now. Non-

renewable sources are not environmental friendly and can have serious affect onour health. They are called non-renewable because they cannot be re-generated

within a short span of time. Non-renewable sources exist in the form of fossil fuels,natural gas, oil and coal.

Renewable energy resources are environmental friendly and clean energy resources

as compared to non- renewable sources. Non-renewable resources usually causepollution and leave waste behind and these resources cannot be recycled so

renewable resources should be utilized more. One day will come when all non-renewable resources will be wiped out of world and then we will have to rely on

renewable resources. We should follow the following proverb and should use moreand more renewable resources instead of non-renewable resources.

Do not put off tomorrow what we can do today.

Dreams seen with closed eyes usually do not come true but dreams seen with open

eyes often come true. If we recollect our mind back in past, we shall come to knowall those dreams seen with open eyes came true .e.g. Wright brothers saw a dream

of flying and they changed their dream in reality with hard work and devotion.

Similarly, many other people of the world came with their dream. We can alsomeet with dream of clean energy if we are determined and want to bring great

revolution in field of generating electrical energy.

Recently, we are using following clean energy resources but these are limited inused.

Solar energy one of the oldest and most reliable forms of renewable energy.

The sun has been around for billions of years, and it is a reliable source ofenergy that can be used to heat our homes and generate electricity

Wind is one of the most plentiful energy sources in the world. It not only

helps to reduce greenhouse gas emissions, but it also can be used to generateelectricity through generators, turbines and other machines.

Geothermal energy is energy derived from deep within the Earths core. It

can be generated from volcanoes, hot springs and geysers, and can be usedto heat and cool homes, as well as to generate electricity.

Tidal energy is energy created by the rise and fall of ocean tides. It can be

controlled by building tidal dams, barrages or fences that harness the energy

of the tides and then convert it to electricity with the help of a turbine Nuclear energy is created when an atoms nucleus is split. There are over

100 nuclear power plants in the U.S. and over 400 across the world, and they

generate up to 17% of the entire worlds electricity

I actually think that the environment would be in a far better place than it is right

now. I know it is hard to be optimistic about the environment, seeing how the

developed and developing countries are at loggerheads on issues of climate changeand how to tackle it. However, 100 years in the future, I see countries utilizing

clean energy (wind energy, solar energy, nuclear energy, perhaps a new, clean, as-

of-now unknown energy source) -- as opposed to fossil fuels. The reason for myoptimism is that there is just no option before humans other than to switch to

cleaner energy sources.A hundred years into the future, therefore, I see vast expanses of land (all over the

world), where wind farming projects have come up providing sustainablerenewable energy. I see the vast majority of cars running on water (yeswater

indeed), causing no harm at all to the environment. I believe the technology for thisdoesn't exist as of yet, although I've seen claims of cars running on water. The

technology though, I believe, can be developed in the future. I see that the thing

called "plastics" is extinct - people are using biodegradable materials insteadthereby saving the Earth of the vast quantities of debris that just doesn't go away,whether in our oceans or on our land. I see that there is no such thing as "paper"

anymore - people therefore don't cut trees anymore. Not even for building houses -composite, unheard-as-of-yet materials have replaced wood.

I see that air travel 100 years in the future is not via the same fuel-guzzling

airplanes we have today. They have given way to alternate-fuelled airplanes,primarily powered by hydrogen-based fuel technology. I see that houses in the

future have discarded the conventional heating systems employed by us now.

Instead, passive houses have become the standard, which rely on the houses' owngenerated heat to heat the house, thereby being more environmentally friendly andbeing energy efficient.
