Energy - ... The relation between agriculture and energy is very close. Agriculture itself is an energy user and energy supplier in the form of bio-energy (Alam, 2005). Energy use in agricultural production has become more intensive due to the use of fossil fuel chemical fertilizers, pesticides, machinery and electricity to provide substantial increases in food production. However, more intensive energy use has brought some important human health and environment problems, so efficient use of inputs has become important in terms of sustainable agricultural production (Yilmaz et al, 2005)....   [tags: Agriculture, Energy Resources] 782 words

Renewable Energy - ... ('Solar Energy,'Renewable Energy for America). Furthermore, they make use of the surplus of energy in the environment. For instance, solar panels are the perfect form of renewable energy generation by making use of the solar energy the planet does not need. Second, renewable energy generators are economic to operate and maintain. Once a renewable energy generator is built, it practically stays for ever and works alone. For example, the British Wind Energy Association says that their wind turbines last from 20 to 25 years with none or minimal reparation, producing about 6,000 Megawatts of electricity per year.('UKWED,' British Wind Energy Association)....   [tags: Energy ]

Environmental impacts of electricity generation and combustion of fossil fuels As mentioned in the introduction, the use of energy is significant to the world as a whole but this comes with a lot of disadvantages. The world relies on non-renewable energy sources as our main source, providing 80% of the world energy use, but this source is a growing concern not because it would eventually run out but because of the environmental impacts the combustion of the fossil fuel is causing globally. Some of this numerous adverse consequences include, air and water pollution, mining accidents, fires and explosions on oil or gas rigs, conflicts over access to fuel resources and, perhaps most overwhelmingly, the global climate change that is likely to be the result of increasing atmospheric carbon dioxide concentrations caused by fossil fuel combustion (Beggs, 2009)....   [tags: Energy ]

Introduction At present, to meet the increasing need of society and environment, bringing in reuse energy and advanced structure are essential in cooling system of intelligent buildings. Cooling means “the amount of heat that must be removed from a building in order to maintain desirable indoor temperature and humidity conditions” (M.Santamouris, 1993)....   [tags: Energy]

Sustainable Energy Systems And Their Benefits - In recent years the research of scientists has come to public attention and it is a widely accepted fact that the Earth is warming up. What has caused this change in the Earth is still up for debate and a controversial issue. One side is that humans are causing the warming by burning fossil fuels. Staying on that topic, fossil fuels are limited in quantity, and some scientists speculate that we may run out sooner than we are ready for. This is where sustainable energy systems come into play. When using sustainable energy systems such as hydro electric, wind, or cruder methods such as waste incineration, burning of fossil fuels will decrease....   [tags: Energy]

Nuclear Power: Energy for the Future - ... This plentiful and powerful source of energy is used to power around sixteen percent of the world. An amazing number considering that a limited number of countries have access to this kind of technology. That number jumps to twenty percent for the U.S.A. and up to seventy-five percent for France, and seventy-six for Lithuania (Rahn). And all of this power has been made creating less damage to the environment. Consumption of fuel in nuclear reactors is around 2,000 metric tons per year, this is a miniscule amount when compared to the tons of coal consumed each year, which is currently 6.74 billion and expected to grow to a staggering 9.98 billion by 2030 (Marshall).All of that coal is burned and turned into pollution that is eradicated into the air....   [tags: Energy ]

Alternative Energy Sources for the World - ... It is found “among the same petroleum deposits that conventional oil is found or in sole gas deposits” (Gotlib, par. 1). This gas has been around since the beginning of time. In the early Chinese dynasty, collected from vents in the ground, the Chinese used this fuel (Gotlib, par. 4). This means natural gas originates in decayed living matter. Instead of utilizing this fuel, most of this gas is burned as excess waste. This gas also must then be stored and transported. If companies collected the gas, it could be used for our current energy needs....   [tags: Energy ]
