Outlines of Essay      Dream and future    What is clean energy?    Hazards of today energy sources    Renewable and non-renewable sources of energy    How dreams came true in past?    Recently being used clean energy    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. Dreams about bright things give us courage, determination and devotion to work for converting 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 one who 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 world is 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 is expensive 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 a carbon-intensity lower than 0.82 metric tons per megawatt-hour (the equivalent of new supercritical coal), or as a result of qualified efficiency improvements 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 the combustion 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 all applicable 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 this  planet. 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 available on 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 on our 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 cause  pollution 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 more and 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 know all 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 also meet 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 in used.    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 of energy 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 generate electricity through generators, turbines and other machines.    Geothermal energy is energy derived from deep within the Earth’s core. It  can be generated from volcanoes, hot springs and geysers, and can be used to 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 atom’s 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 world’s 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 change and 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 my optimism 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 sustainable renewable energy. I see the vast majority of cars running on water (yes  –   water indeed), causing no harm at all to the environment. I believe the technology for this doesn'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 instead thereby 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' own generated heat to heat the house, thereby being more environmentally friendly and  being energy efficient.
