Today’s society encourages us to change our lifestyles and become more environmentally friendly. There are numerous theories and facts about global warming and one of those is to increase the use of renewable energy sources. There is unprecedented interest in renewable energy, especially solar and wind energy. Renewable energy sources provide electricity without giving rise to carbon dioxide emission (World Nuclear Association). It is impossible to convert to these sources completely, however there are things that we can do as individuals and as communities to be more environmentally friendly . As humans advance in technology, the amount of fossil fuels burned is increased at a rapid rate. This is an issue because with this increasing rate, the Earth is becoming polluted at an increased rate as well . This pollution is becoming very relevant due to the fact that we, as humans, are allowing it to destroy different life forms and terrains that earth has to offer and most importantly, the ozone layer. An alternative option to this issue has been brought up all around in the science world, this option being that humans use the natural resources that we have around us, such as, water, wind, and the sun. This option is a double win because it will allow less pollution and let humans use less of the fossil fuels that have a limited supply of . There are many different ideas that scientist have come up with for these alternative options, but three main options stick out and those being hydropower, solar power, and wind power. Hydropower is the idea of using water to create energy that is renewable. Hydropower, the leading source of renewable energy, has played a large role in decreasing pollution around the world.

Instilling this new way of energy usage into off-grid communities will inevitably increase the state of living for those in cities and other well populated areas. The change to renewable energy sources could drastically lower the pollutants currently being dispersed into the atmosphere by coal mines and other harmful power options,
Not only is nuclear power friendly to the environment, but it is almost always available, and many countries are starting to use it more. Renewable energy sources like solar and wind en...

Hydro power is one of many examples of alternative energy source. Hydro power is producing energy by moving
...ination, hydrogen fuel and solar energy (World Economic Forum 2014). These are technologies that closely related to environmental and recourse preservation, which help the society switch to use renewable energy.
One efficient way to acquire energy is Hydropower. Hydropower is power derived from the energy of falling water or fast running water. This energy converter is harmless to the environment. Other ways will affect the atmosphere and the environment in a negative way. The most common device for hydropower is a dam. It relies on the water cycle. This is one of the oldest sources of energy.
Next, hydro-electricity is electricity produced by moving water, flowing past a turbine connected to a generator (“Hydropower”). According to Nationalgeographic.c...
Scientists used experimental methods and statistical analysis to prove that human activities cause global warming, through emission of greenhouse gasses, deforestation and the use of chemical fertilizer. Environmentalists and scientists are trying to enlarge the use of renewable energy technologies e.g. solar and wind energy. Plantation of trees can also reduce global warming at a large scale by absorbing carbon dioxide. Use of animal manure instead of chemical fertilizers can reduce exhaustion of ozone layer. The use of renewable energy source together with human cooperation can make this environment better place for present and future generation.
Now days, the world is intended to be in a worst scenario ever imagined. Climates, global warming and furthermore problems. However, I have noticed new changes, universally speaking, yet renewable energy has also been popularized to our world and I addition, it became part of Sustainable Architecture. “Sustainable Architecture describes the fact that we can only exist and create with the availability of natural resources. Those resources are the foundation of our world. Sustainable architecture proclaims this fact to the world… And that is probably the most appropriate understanding of the term.”(Brooks, 92) That’s why these resources exist within our environment but only few of the people anticipated a good use for them just t increase likelihood the worlds energy efficiency and also the natural environment. Speculating Asia’s growth both in wealth and population, it has been a great risk for them consequently they had been temporizing endeavoring new ways of preventing massive energy consumptions and wastes from resources. “How can we protect our natural resource base while sustaining our socio economic gains? My answer in two words: systems and self.”(Ms. Galang, 1)
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
Hydroelectric Power Plant is when electricity is generated when water in an uphill reservoir flows downhill. The gravitational potential energy of the water changes to kinetic energy of the flowing water which drives the turbines to generate electricity. The efficiency is more than 90%. The environmental impact is Floods large area and affects the ecology of the area, May cause drought downstream if not managed properly, does not cause ai...
Hydroelectricity is a known renewable energy resource that provides substantial benefits for our wealth, our health, and for our global economy. There are five types of renewable energy we can use on a daily basis throughout our lives, but the most widely installed form of renewable energy is hydroelectricity. Hydroelectricity is electricity created by converting the kinetic energy of flowing water. Best thing about this source of energy is that it’s timeless and renewable, which means it will never run out, however we had to figure ways to store this energy. In order for them to harness this energy for other people, they had to build generators that convert all the potential energy of rapid moving water into electrical energy.

In the search for alternatives to fossil fuels, scientists and policy makers have focused on three options: nuclear power, energy from biomass; and a combination of wind, water, and solar power. Nuclear power, however, is much more costly and runs the risk of having it fall into the wrong hands where it could be turned into a weapon of mass destruction. The third option entails wind turbines, photovoltaic power plants and rooftop systems, concentrated solar thermal power plants,...
Using fossil fuels such as coal and oil is inefficient, dangerous, and otherwise a process that is known to eventually fail as a long lasting energy source. Yet, there is hope for the future of energy, this new hope has many shapes and forms, but requires a chance to be fully implemented in our everyday life. Such energy sources like solar energy, wind energy, geothermal energy, and hydro power are the key to our future. These energy sources are proven to be long lasting, safe, more reliable, and the next innovation. In short, all Americans should switch to renewable energy, resulting in a safer and more efficient world.
Imagine a life without lights, televisions, computers, trains, washing machine, refrigerators and microwaves. Imagine a planet so polluted that smog is in the air so bad that one cannot see very far, lakes and streams are poisoned, and land so badly scarred from people trying to find more energy sources. This may become reality in nearly future as a result of abuse of our energy resources. That reveals that energy is most important in our life, while a planet where we live is important too, a planet which effected by both generate the energy to meet our demands, and our use of energy.
