The Effects Of Renewable Energy On The Environment

Wind turbines have altered the way that we get our energy. Wind turbines are used to harness wind power and turn into electricity. They are comprised of usually 2 or 3 blades that are connected to a shaft that was attached to a generator which then turns into electricity. Although we now generally use it to produce electricity, wind energy was originally used in the form of windmills to do chores and housework. Because of the rapid increase in the use of wind turbines, it has added jobs and changed the way we get energy.

The term "renewable" in relation to energy refers to a natural power source which can be replenished on a human time scale. For example, coal and oil may both be replenished but cannot be considered "renewable" sources as the process is not easily replicated artificially and therefore takes millions of years to replace what has been extracted from the earth. The use of sunlight, tides, waves, wind, geothermal heat and biomass are examples of natural power that are considered renewable sources.

Renewable energy is energy from a source that is not depleted when it is used.

Wind energy, one of the oldest forms of renewable energy used by humans, is produced simply by harnessing the power of the wind with wind turbines and generating electricity. Geothermal energy is energy from the heat of the Earth, and is drawn from locations with naturally heated water like hot water reservoirs and geysers or areas deep within the Earth accessed by drilling (NREL, "Learning About Renewable Energy"). Hydroelectric power, in simplest terms, uses the power of water rushing downwards to rotate a propeller attached to a generator that in turn produces electricity (Perlman). Another form of renewable energy is biomass, such as wood, biofuel, and bio-waste, which is burned to produce energy; however, it is not clean energy.

Everyone uses a lot of power for lighting, heating, machines, movements, and so much more. All of that energy has to come from an energy supply. Some energy resources are renewable, while others are non-renewable. Energy has various forms and is a very essential part of our everyday lives.

Renewable energy is energy that comes from any natural process and can be quickly regenerated. Some of the most common forms of clean energy include solar energy, wind energy, and hydroelectricity. These types of electricity are gathered through technology such as solar panels, wind turbines, and hydroelectric dams. Other types of renewable energy less known include geothermal energy, biomass energy, and energy collected from ocean (Renewable). Geothermal uses the Earth 's heat to generate energy while biomass use plants and other organic materials to make energy and fuels. Ocean energy can be derived from a multitude of areas. Energy can be gathered from the tides, the wind, and can also be gained from the

What exactly is renewable energy? In the terms of The Natural Resources Defense Council (NRDC, 2015), renewable energy comes from sources that can be replenished easily. Solar power, wind energy, hydroelectricity, geothermal, and biomass energy are all examples of this. All of these sources can be replenished, or renewed naturally. Wind energy is free of pollution and costs about the same as electricity from coal. Solar energy is growing cheaper, and is used in many every day appliances. Biomass energy uses materials such as wood, corn, soy, and sometimes animal waste. It takes time for biomass energy to grow, but it is a critical renewable resource. Hydroelectricity is energy produced by flowing water and accounts for six percent of America’s electric supply (NRDC, 2015). If we can make the transition to a future of cleaner energy sources, we can eliminate our dependence on fossil

Green energy is just another term to describe any sort alternative energy that is produced with less negative impact on the environment. Renewable energy is green energy generated from natural resources such as sunlight, wind,

International Energy Agency then after IEA defines renewable energy as energy derived from natural processes e.g. wind and sunlight. Moreover, renewable energy is replenished at a faster rate than consumed such as solar, wind, geothermal, hydro and some forms of biomass.

Wind Power is power obtained by harnessing the energy of the wind. Uneven rays, temperature, and the rotation of the earth are what cause wind, warm and cold, which in turn provides energy. Wind turbines are the main items used to provide energy from the wind. Wind turbines have large blades that turn in a circular motion at the top of the tower. As the blades turns, it causes a shaft to turn as well inside the tower. The shaft is connected to a generator which generates electricity. These wind turbines are placed on either onshore or offshore wind farms. Onshore wind farms are placed on ridges, hills, and seashores, since those are the best areas to catch wind. On the other hand, offshore wind farms are not only very difficult to build and maintain, but on the bright side, pick up more wind than onshore wind farms since they are placed in the sea (Fridell pp. 13-18). This source of energy is good to use since it is very efficient because the wind usually occurs around the world. Wind energy also provides jobs. Wind jobs are growing 12 times faster than other industries. And, a wind turbine technician is the fastest growing profession in the United States (Samuelson 2017). Also, just one wind turbine can provide energy for several houses. For example, In the book, Earth Friendly Energy on page 34, It states, “In 2005 the total was 58,982 megawatts. On the average, one megawatt of wind power can serve 160 U.S

Nowadays, energy is pivotal to almost every major challenge and opportunity the world confronts. Be it for jobs, security, climate change, food production or increasing incomes, access to energy for all is essential. Sustainable energy is needed for strengthening economies, protecting ecosystems and achieving equity. In accordance with The UN Conference on Environment and Development, energy consumption is expected to increase dramatically over the next 50 years as the world’s population grows and developing countries become more industrialized. With environmental requirements for lower CO2 emission sources and the need to invest in a sustainable energy mix, new energy sources must be developed. At the same time, climate change is known to be one of the most

Bilen et al., (2008:1531) predicted that global energy consumption will account for around 85% of the increase in world primary demand over 2002– 2030. The increasing of global energy demand happens the global stock of fossil fuel resources may be adequate for short term period, thus requiring the development of renewable energy sources, which would not decrease the stock of fossil fuel resources available for future generation. There is an increasing interest in the development of renewable energies such as biofuel and wind power, which have a great potential energy to produce enough power for the world’s population demand.

Over the years, the unequivocal increase in the Earth’s climate has been an issue concerning environmentalists and other scientists. With overwhelming evidence pointing to environmentally damaging human behavior as the culprit for the Earth’s rising temperature, a search for cleaner and renewable energy sources creates a vastly growing alternative energy industry. One of the most widely used forms of renewable energy is hydroelectricity. Like the name implies, hydroelectricity refers to the generation of electricity through use of hydropower. In particular, the gravitational energy of falling, flowing, or spinning water can be transferred to electric energy through Newton’s Law of Conservation of Energy (i.e. energy cannot be created or destroyed, but can be transferred from one form to another).9 This renewable energy source has grown in popularity vastly over time since the industrial revolution, and now accounts for nearly 15 percent of the Earth’s total electricity generation.9 The benefits hydroelectricity speak for themselves; hydroelectricity yields no direct waste, has a relatively low costs and expenses, and releases considerably less carbon dioxide emissions than the burning of fossil fuels. However, some recent studies have suggested that the vast benefits of hydroelectricity do not outweigh the damaging effects on the surrounding ecosystem.

Renewable energy is energy or power that is created from natural resources such as wind power, oceanic waves, and the sun. These resources can be used to replace other energy generators such as electricity and gasoline.

Energy that can be re-used or re-grown in a shorter period of time than, for example, a fossil fuel, is the simplest way of defining renewable energy. It is considered very eco-friendly as energy from resources such as oceans, the sun and the wind contribute very little to pollution overall when producing energy. The energy problem which we are faced with today is critical and governments, scientists and environmentalist continue to search for various solutions which will alleviate the issue. In this paper, the causes of the energy problems that exist will be explained. This paper will also include a balanced discussion on the ways in which renewable energy could be the solutions
