Renewable Energies : Renewable Energy

The time has come, we’re running out of fossil fuels and we need an alternative. That is where renewable energy comes in; The best part about it is that it is renewable so it will always be available to us, and we can acquire this energy through solar, water, and wind power. There is a lot of controversy as to whether we should rely on renewable energy, because some say it is not cost effective. However renewable energy can pay for itself, is available nearly everywhere through various methods of obtaining it, provides numerous amount of jobs and economical benefits, and it will not harm our environment.

Moving into the next renewable energy, there is a big advantage that hydroelectric power is that hydropower dams is a huge renewable resource and using water to create electricity has no carbon footprint. As well as there is less pollution from it overall. There are many advantages but there are two distinct disadvantages, one of them being the cost to build an electric power station. The cost

Hydropower is a renewable resource that is clean, affordable and durable. This resource is clean due to the way you gather the energy from it. hydroelectric and coal-fired power plants produce electricity in a similar way. In both cases a power source is used to turn a propeller piece called a turbine, which then turns a metal shaft in an electric generator (the motor that produces electricity). A coal-fired power plant uses steam to turn the turbine blades; whereas a hydroelectric

Renewables are better environmentally than any other power source under specific circumstances. The two most touted renewable energy sources are wind power and solar power. The specific circumstances in which they are better are when the wind is blowing and the sun is shining. Unfortunately, neither the wind nor the sun can be guaranteed to function for any specific date or time. The sun can only be guaranteed not to shine for approximately twelve hours a day and wind has no guarantees at all. Also, technology is not advanced enough to adequately harness the power provided by the sun and wind when they are available. It would take five hundred times the amount of land to build a solar plant with the same output as a nuclear plant (Oliver Hospers 24-25).

Hydropower represents 19 percent of the world 's total electricity production and has several distinct advantages compared to other traditional power-producing methods. Hydropower plays a major role in the reduction of greenhouse gas emissions since it does not require any fuel burning, potential energy (i.e. water) supply

Hydro-electric dams are not an environmentally friendly form of producing energy because is will cause people to relocate. In Canada, there was a dam approved to be built in 1958 which caused over 6,500 people to relocate. Hydro-electric dams need large amounts of water in order for the dams to meet the electricity required. Therefore, they need large reservoirs. These big reservoirs and high amounts of water decreases the land area for people and animals to live in. In conclusion, hydro-electric dams are not an environmentally positive form of generating energy, it will cause people to relocate.

Biomass energy is a renewable energy source from living or recently living plant and animal materials which can be used as fuel. There are many ways in which we could produce this energy such as heat and steam. Also, instead of leaving waste in landfills, we’re reusing that waste and converting it into usable power. Pros: 1. Renewable. 2. Dependency on Fossil Fuels is Reduced 3. Protects air quality 4. Improves forest health. Cons: 1. Not 100% clean. 2. Requires a lot of water. 3. Not as efficient as fossil fuels.

Its powers most of the building like homes, hospitals, schools, factories and etc. Hydroelectricity comes in a human cost. The huge damn that required for hydroelectric energy projects create a reservoir that floods an entire valley. Like homes, communities, and towns that may have to relocate as a dam construction begins. However, the projects to make a hydroelectric power generator has forced more than millions of people to relocate. Lifestyles were disputed. We don’t have to burn fuels to cause pollution… pollution free. Hydroelectric developments don’t generate toxic by-products. With an average lifetime of 50 to 100 years, hydroelectricity developments are a long term. It can easily be upgraded to incorporate more recent technologies and have very low operating and maintenance cost. Dams are designed to last decades and so can so contribute to the generation of electricity for many years and decades. Hydroelectricity is the cheapest way to provide energy. Once a dam is constructed, electricity can be produced at a constant rate. Large dams can be useful for flood control. It’s a clean energy source. It does not produce green house gases. When a hydroelectricity water storage dam is built, the water can be used as drinking water and also a recreational purpose such as fishing and boating. Dams saves and reserves water so that it is not wasted into oceans and seas. Controllable source of

Renewable energy is considered an environmental friendly way of producing energy; according to http://www.renewableenergyworld.com/index/tech.html, “in contrast, the many types of renewable energy resources-such as wind and solar energy-are constantly replenished and will never

Support: Solar power has very little pollution, uses no greenhouse gases and is a renewable source.

When the new Southeast Polk High School opened they added many new energy saving products. This included installing geothermal heating under the high school cutting back on the cost of heating such a large building. Many new windows help save on energy used to light the building along with automatic lights that turn off after several minutes without movement. The new high school shows how easy it is to save money and help the environment. Renewable energy is good for all aspects of the U.S, providing jobs, economical growth, environmental cleanliness, and new research for improving energy efficiency. Therefore the United States should use renewable energy to benefit the economy and environment.

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,

While Hydroelectric dams have many benefits/[a specific benefit]. There are many environmental drawbacks to hydro electricity. Hydroelectric dams are massive constructions of concrete cutting across parts of the wilderness. The dam itself completely intersects a river. Hydroelectric dams treats water like an inorganic resource, much like Liquid oxygen? and Nitrogen? in a rocket. However the water is also a crucial part of the ecosystem for Flora and Fauna both in and around it. Its hard to use water as a storage for gravitational potential energy as well as an ecosystem, and dams often drastically affect aquatic life

By 2030 the world is expected to be more economically friendly and efficient when it comes to resources. Advanced technologies are being created to accommodate to the worlds high demand of energy. With all the emerging innovations, are world is becoming something far greater. Renewable resources are the key, they are the

Renewable energy may seem like a daunting task, but the benefits to humanity could be incredible. Public uses of renewable energy range from transportation all the way to heating and cooling. Everything we use could become less explosive and less expensive. Cities with a high concentration of people could become safer and healthier places to live. Transportation could be converted to electricity dramatically, improving smog conditions. Global warming may or may not
