non-renewable energy resources. Hello there! A very good morning and I am Pranav Athreya and you have guessed it right‚ I am speaking for the topic Renewable energy is the need of the hour. At present‚ the main energy sources used are non-renewable fossil fuels like coal‚ petroleum‚ and natural gas. There are many disadvantages in using these non-renewable energy sources. Irreversible damage to the environment by pollution and global warming‚ damage to the eco systems and threat to Life itself. So my

global warming. Running a single 1-MW wind turbine can displace 2‚000 tons of carbon dioxide in one year (equivalent to planting one square mile of forest). Wind energy is cost competitive to other fuel sources (like natural gas) and it is the least expensive of all renewable energy sources. Because the fuel (wind)

by about 80 percent during that time. The amount of CO2 in the atmosphere today far exceeds the natural range seen over the last 650‚000 years. Most of the CO2 that people put into the atmosphere comes from burning fossil fuels. Cars‚ trucks‚ trains‚ and planes all burn fossil fuels. Many electric power plants do‚ as well. Another way humans release CO2 into the atmosphere is by cutting down forests‚ because trees contain large amounts of carbon. People add methane to the atmosphere through livestock

The 11th hour Story of the film film is preceded by the introduction of the environmental problems that plagued the world today. This introduction is intended to give an overview to the viewers about the negative impacts caused by human activities that are less responsible for the stability of the environment in general. Then proceed with the analytical discussion about things that appear in and around the environmental issue‚ and ended with optimistic statements proposed to raise the confidence

Part B: Summary In his article ‘Fossils Fuels Improve The Planet’‚ Mr Alex Epstein’s main claim was that fossil fuels are not dirty energy as they have created clean‚ healthy and liveable human environment. He also concluded that unlike fossil fuels‚ solar and wind energy - dubbed as cleaner energy - are expensive‚ unreliable and not abundant. He began by arguing that fossil-fuels-powered technologies and facilities have enabled humans to live in the most clean‚ healthy and liveable condition in

the amount of carbon in the atmosphere climbs! (Venkataramanan‚ M & Smitha 2011) One of the human activities that contribute to global warming is the burning of fossil fuels. This activity is the primary human cause of global warming as it is the main contributing source of greenhouse gas (Venkataramanan‚ M & Smitha 2011). Fossil fuels such as coal‚ oil‚ gasoline and natural gas (Feinstein‚ D 2006) are carbon-based and will produce carbon dioxide as it was once alive as plants or animals (Wilson

temperature. I believe are affecting global warming by burning fossil fuels. I think this because of the sea level‚ burning of fossil fuels‚ and deforestation. One reason I believe humans are affecting global warming is because the ocean has risen about 4-8 in the last 100 years. That may not sound like that much but it’s a significant amount. In an online article it says‚ it’s getting hotter because humans are burning fossil fuels which trap heat and energy into the atmosphere. Thus heating up

only cause of the change in these conditions. The world’s increasing the usage of fuels and petroleum day by day increases the world’s average temperature. I agree that they have a major role in our lives and I also agree that we need them to do our daily chores but this increase may end up as very tremendous and huge worry to everyone living on the planet. The gases that come out after the combustion of these fuels and also from the chimneys of the factories‚ combine and add up the concentration

In current society‚ the problem of the climate issue and of the finite nature of fossil energy sources is becoming increasingly serious. The need of renewable and clean energy becomes extremely urgent. But in the meantime‚ solar energy as new type energy cause people concern. In addition‚ whether using solar energy to protect environment

SOLAR TREES In modern days the use of non renewable resources is being a major part of lab works. There are different types in these sources‚ but the utilization of them is must. In an age of global concern for escalating fossil fuel prices‚ energy security and CO2 emissions‚ a fervent demand for sustainable energy sources endures. In apt response to this critical issue‚ a renewable alternative energy innovation is receiving wide spread interest and attention. Hence the development
