Renewable energy development

efficient source of energy. There are many common sources of energy, and they all have their own flaws. Many of the common energy sources are nonrenewable resources; therefore, they are not a logical source of energy for the future. Some of the energy creating processes can be very dangerous to humans and the environment. Many of these sources are not economical either. To be considered efficient, an energy source must be feasible, safe, and economical. Coal is a commonly used source of energy.…

alternative energy source so that we do not run out of fuel. We need alternative energy for many reasons mainly because we are running out of fuel but also because we are polluting this world, alternative energy can produce “clean” energy that will provide a new power source without polluting this world. In this article I will talk about these and other problems with our current power generation methods: Fossil Fuels. Alternative Energy, a big word that could mean so many things, Alternative…

even referred to as the energy source of the future. To the uninformed the use of nuclear energy may seem frightening because the only thing rumored is the negatives like: the waste, major spills of material and disastrous radioactive accidents, but there are many benefits from the use of this energy source such as: saving millions of lives, a mass reduction of pollution, and an advancement of technology. Although it may take a long time, society will benefit from this energy source. The…

Petrobras is a Brazilian oil company that was created by the Brazilian government in 1953. For the first decade Petrobras struggled to be successful despite being given a constitutional monopoly by the Brazilian government. Brazil did not have any oil reserves or the knowledge in oil exploration, and the goal for Petrobras was to become a world class oil producer. Petrobras began to see success in the 1980s when they developed deep water and ultra-deep oil production. This new technology…

electricity. Throughout many years of only fossil fuels, there is now hydroelectricity, photovoltaics, solar thermal, geothermal, and wind power to supply energy to society today. As a result of advances in technology, breakthroughs were formed in the way humans use photovoltaics and solar thermal. Carnegie Mellon University, the publisher of “Energy Sources, Technologies and Impacts” states, “To convert solar radiation into electricity, we use photovoltaic cells… based on the phenomenon of…

be to keep global temperature increases under 2 degrees Celsius. With such high expectations, the US and other countries around the world need to invest in new power producing technologies in order to phase out the fossil fuel industry. While renewable energy sources such as solar and wind are the best long term solutions, their unreliable, inefficient, and expensive technologies make them unusable to reach the 2050 goals. To reach the desired carbon goal, countries around the world need to…

mAhg-1) occurs at a reversible plateau around 0.3 V versus Na/Na+, however, to achieve this capacity, a slow cycling rate (C/25) and a composite electrode with 30% super P carbon black are necessary. The large amount of carbon additive decreases the energy density and causes large irreversible capacity, which is of the same order of magnitude as the reversible capacity observed at the first…

the transports would have to deliver not only food, but coal for heating. The bags of coal would be bulky and take up most of a plane’s space. As the airlift’s operation increased it exceeded General Smith’s capability. As a result, the duties of running the airlift were given to the Military Air Transport Service and a new commander Major General William H. Tunner. General Tunner had previously operated an aerial supply line during World War II that crossed the Himalayas, from India to China.…

In comparison with Europe the US market is two times bigger and is expected to rise to $1.605 million in 2010. Natural gas is currently the second most important source of energy for Europe, meeting around 25% of primary energy needs, forecast to rise towards 30% by 2020. Although gas demand is growing in all sectors of the economy, it is particularly strong in power generation, because when it is used instead of other fossil fuels, CO2 emissions…

This informative article by Lutz Kilian discusses shale oil and its effect on oil prices in the United States. Shale oil is a term used by the oil industry for oil that is obtained from low-permeability rock, and it has caused a resurgence of oil production in the United States. This type of oil production was not available until quite recently, because of several technological advances in the industry. Currently, shale oil production, mostly from western states, accounts for a sizeable amount…
