Energy dependance and renewable energy sources Executive summary The United States of America is facing a growing problem with regards to energy dependence.
Capturing sunlight and converting it into energy does not generate any air or noise pollution. As long as the sun comes up, more energy will be produced. The energy potential from the sun is staggering if we were able to harness all of it. The surface of the earth is bathed with enough solar energy in one hour to meet the energy needs of the entire planet for a year, if we were able to somehow capture all of it.
Great Choice for Remote Locations: Often cheaper to set up solar than run high voltage lines to remote areas off the power grid. Cons Expensive to Set up: Initial setup cost is the largest con for solar energy.
Some states will provide tax credits or other subsidies to try and help offset the cost, but it is still one of the more expensive alternatives to set up. Efficiency Affected by Environmental Factors: Besides the obvious drawback of only producing energy during the day, the efficiency of solar cells can be negatively affected by cloudy days or excessive pollution.
Large scale solar plants currently require wide areas of open land to produce power levels comparable to a traditional power plant. Technology to increase efficiency is always improving though. Wind Humans have harnessed the power of wind for centuries, from windmills to grind grain to sailboats used to travel across the oceans.
These days large wind turbines can be used to create electricity. Using wind power does not generate any air pollution like fossil fuels do. It will continue to blow whether or not we harness it, and harnessing it does not reduce its supply in any way.
Wind direction and strength can be unpredictable and inconsistent, making wind as a primary energy source non viable. Wind turbines are not silent, and usually produce around decibels of noise with their use.
People living near wind turbines often complain about the noise they create. This disadvantage is reduced by building wind farms offshore or in remote, rural areas. Since wind turbines are located typically in rural areas, many people think of them as a blight on the otherwise untainted landscape.
Wind turbines can be dangerous to birds or bats in the area.Jul 01, · Carbon Dioxide Essay; Carbon Dioxide Essay.
Carbon Monoxide Essays. The cycle works in a very basic way. First, carbon is taken from carbon dioxide found in the air. Plants take in carbon dioxide from the atmosphere. material or feedstock should be renewable rather than depleting whenever technically and economically viable.”1 .
Carbon dioxide is a simple mixture of exactly what it sounds like; one part carbon with two oxygen atoms attached to it.
The Effects Of Carbon Dioxide Environmental Sciences Essay. Print Reference this. Disclaimer: The carbon is then drawn into the soil through the roots of the agricultural crop or tree. This is nature’s way of. This free Environmental Studies essay on Essay: Energy dependance and renewable energy sources is perfect for Environmental Studies students to use as an example.
This results in about billion megatonnes of carbon dioxide emissions from the consumption of energy . About this resource. This Environmental Studies essay . Alternative Energy Sources For Renewable Energy Essay - While this may only be approximately % of all carbon dioxide emissions from the year before, it will eventually add up likewise making the negative carbon dioxide deposits cease to exist.
Renewable vs. Non-Renewable Energy Resources Words | 8 Pages. Renewable Vs. Non-renewable Energy Resources: Environmental and Economical Advantages and Disadvantages Imagine a life without washing machines, dryers, refrigerators, computers, televisions, lights, and cars.
The result of this burning is typically water vapor, ash, and carbon dioxide.
Water vapor is not harmful to the environment but carbon dioxide and ash are. Carbon dioxide and ash are pollutants, which cause problems in nature. Renewable Energy & Nonrewable Essay We will also identify the risks and benefits of extracting or using one.
