Does Green Energy Supplies Enough for Our Life?
Title: Does green energy supplies enough for our life? Nowadays, the problem of global warming in all around the earth became more serious. In other countries, the iceberg keeps melt because of the global warming causes the temperature of earth increase. So, in order to save our environment, one of the important ways we can do to save the environment is using green energy. Green energy is the energy that produces little products but no harming the environment. We think that the green energy will supplies enough for our life. There are many types of green energy that we can use to supply our daily life such as solar energy, wind energy and bio energy. Firstly, we can use solar energy to supplies our daily life. Solar energy comes from an average star- the sun. It provides enough energy in one minute to supply the world 's energy needs for one year. It can use for solar process space heating and cooling system. Solar process space heating system will provide large quantities of hot water for household uses. Besides that, the solar energy also can use for cooling system that combined with some very complex chemistry tricks to create the cool air. The solar energy also can be used for photovoltaic systems. It uses solar panels to convert sunlight into heat, applies it to a steam generator and then converted it into electricity in order to warm the buildings, heating the water and generating electricity for community use. Secondly, we can use wind energy to supplies our daily life. Wind energy is the fastest growing energy source and consumes no fuel for operation with no emissions and zero pollution to produce the electricity. The most comprehensive study to date found the potential of wind power on land and near-shore to be approximately 72 terawatts. It converting 20% of potential wind energy to electricity only to satisfy the world 's energy demands. It also use in other country such as India. India is the fourth largest generator of wind power in the world

    Energy is an important part of our everyday lives. Energy can come in many different types, and forms it can be used for many different purposes. Energy has many different usages and can be converted from one form of usage to another form of usage depending on what the need is. One form of energy conversion is the use of food to supply people's bodies with energy. Another form of energy is how coal is converted into electricity. Fuel is another form of energy that can be used for many different usages as well. Fuel is used for much different reason such as allowing our cars to function and our lawnmowers to cut grass. There are many different reasons why people use energy in the many different ways that we use it. Even though people rely on energy usage, some of the forms of energy we use are very harmful to the environment and even dangerous to ourselves. The harmful and dangerous fuels that we use can be changed to alternative methods of energy usage. There are two different types of alternative energy, which is known as renewable energy. Renewable energy is very resourceful and is able to be used because it is all around us there will not be a shortage of material and it is safer on every living thing and being. Energy and fuel usage just like everything else in the world has its advantages and disadvantages about using it. We must collectivity figure out which source of energy is right for everyone but for now we will find out which is best to use in your…

    Green living and renewable energy has been a hot topic in discussions for years. Politicians, environmentalists and companies have made their points on both sides of the argument and tried to force their beliefs onto the public. The masses have now heard how renewable energy helps reduce pollution and how expensive it would be to switch our lifestyle but I don’t think many people know why we need this change or why it is not necessary. Green living has been shown to help reduce our carbon footprint and help the planet but others are saying that it is a waste of money and not necessary in order to survive.…

    Solar energy is lauded as an inexhaustible fuel source that if free of pollution and has very few adverse effects on the earth. An example states that big windows placed on the sunny side of a building allow sunlight to heat absorbent materials on the fllor and walls. These surfaces then release the heat at night to keep the building warm. Similarly, absorbent plates on a roof can heat liquid in tubes that supply a house with hot water. (National Geographic) In my own life, I have experienced the amazing power of solar energy. As a small child growing up in Guyana, South America, I remember taking cold showers in the morning. By the afternoon time, the sun would heat up our plastic, Rubbermaid water tanks and I would experience for a short period, ‘hot water.’ Of course, this has improved over the years, and many households in my country choose to apply solar water heaters to their homes. This helps to save on electricity and other costs.…

    Today nearly half of the world’s energy is provided by petroleum. What began as a cheap and abundant way to provide energy, has become expensive, environmentally harmful, and finite. With population explosions and the demands of modern lifestyles, the world’s need for energy production has become far too much for fossil fuels to keep up with. Experts say that the Earth’s stores of petroleum will be depleted by 2050. The need to find a viable source of energy within this generation’s lifetime that can power cars and provide electricity to homes. Some of the alternative energy sources include: wind energy, nuclear energy, and solar energy. Of the three, only solar is capable of producing enough energy to power the world. Solar energy producers fall into two separate categories: thermal solar collectors and photovoltaic panels. Thermal solar energy collectors are “a source of hot water that can be used for heating or for making steam to generate electricity” (Nersesian 2007). They are the simpler of the two types and much more inexpensive. They have many practical applications such as pool warmers and water heaters. Photovoltaic panels convert solar energy directly into electricity. They are large and the technology is still fairly expensive. Solar energy is a viable option to replace fossil fuels because it is the most financially viable long term, is a renewable resource that will not harm the environment, and each system can operate independently.…

    The first contribution for sustainable environment by new technology is helping people to explore sources of renewable energy. This means that with the help of new technology, people can make full use of natural sources to create green and renewable energy that people cannot image nor realize before. Such as tidal power, wave power, solar power, wind power and so on. According to Jamie Frater (2009), “These sources of energy provide an alternate ‘cleaner’ source of energy, helping to negate the effects of certain forms of pollution. All of these power generation techniques can be described as renewable since they are not depleting any resources to create the energy.” For instance, the wind power, people set wind turbines to transform wind energy into electricity or mechanical energy. In the process of creating energy, there is no consumption of resources. It…

    Green energy is energy that is produced in such a way as to minimize its negative impact on the environment. Traditional energy sources, most notably fossil fuels, produce greenhouse gases that are believed to be the primary cause of an effect known as global warming or climate change. Sources of green energy, such as solar, wind, geothermal, and hydro energy, are developed and promoted as alternative sources that make little or no contribution to climate change. Even nuclear energy is sometimes considered a green energy source, because some types of nuclear technology produce much less waste than oil and coal.…
