Right now oil provides more than 40% of the total energy consumed in the United States; natural gas and coal provide about 30% and 20% with nuclear and other energy provide the remaining 10%.]]> 2019-02-13 15:08:32 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/330838062 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/330851851 The efficiency of converting the thermal energy in fossil fuelsto  work energy is low for almost all power. To combust the fuel it requires a high temperature, but things like mechanical losses like friction makes it hard to be efficient. New technology using coal in power generation could increase effIciency from 30 to 40%, and advanced combined generation using natural gas could raise it to about 60%.Advanced technologies will be able to moderate the rate off C02 emissions.]]> 2019-02-13 15:29:32 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/330851851 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332159211 Methanol produced from natural gas has been considered either a gasoline substitute or a blending component of gasoline to reduce air pollution. In recent years, oxygenates have been produced as gasoline additives to reduce air pollution in the United States. Methyl ether (MTBE), made by reacting methanol with isobutene, is an example, but now a few states have outlawed the addition of MTBE to gasoline because it causes unpleasant side effects such as headaches, it has found its way into groundwater, and it is a suspected carcinogEn. ]]> 2019-02-17 20:12:26 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332159211 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332159728 The petrol refining industry is continually changing federal mandates on fuel composition. Instead of building new facilities, the industry elects to limit its investment to the modification of existing facilities in order to satisfy these mandates, namely, reduction of benzene and aromatics in gasoline, reduction of sulfur in all liquid fuels, and purchase or synthesis of oxygenates. ]]> 2019-02-17 20:15:56 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332159728 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332160082 We rely on coal, oil and gas (the fossil fuels) for over 80% of our current energy needs – a situation which shows little sign of changing over the medium-term without drastic policy changes. The potential for crisis if we run out of energy is very real but there is still time before that occurs. In the past two decades proven gas reserves have increased by 70% and proven oil reserves by 40%. At expected rates of demand growth we have enough for thirty years supply. ]]> 2019-02-17 20:18:16 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332160082 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332160501 Today, oil and gas reserves are in the hands of a small group of nations, several of which are considered political unstable or have testy relationships with large consuming countries. Eighty per cent of the world’s proven oil reserves are located in just three regions: Africa; Russia and the Caspian Basin; and the Persian Gulf. And more than half of the world’s remaining proven gas reserves exist in just three countries: Russia, Iran, and Qatar. ]]> 2019-02-17 20:20:27 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332160501 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332160801 For the first time we face an energy crisis not because we might run out of energy, but because we are using it in the wrong way. Up to now the energy industry was judged by two things, its contribution to energy security and the cost of energy delivered to the consumer. To this we must now add a third: its success in reducing the emission of greenhouse gases, mainly carbon dioxide, into the atmosphere.]]> 2019-02-17 20:22:36 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332160801 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332161304 Reduce growing energy demand through improved energy efficiency and conservation. The first step to reducing global emissions is to downgrade the growth in energy demand with a goal to eventually setting it on a downward trend. The key for continued economic progress is to learn how to create more wealth with less energy. This has additional benefits in improving energy security, preserving precious natural resources and saving money for businesses and the ordinary consumer..]]> 2019-02-17 20:26:25 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332161304 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332161833 Global warming has become important to the melting of ice, climate change, and rising sea levels.This is now recognized by nearly everyone as caused by greenhouse gases, mainly carbon dioxide, produced by burning fossil fuels such as petroleum, coal, and natural gas. While nuclear power plants are being advocated by some, dealing with spent nuclear fuel is as problematic as greenhouse gases, and energy must be used to produce nuclear fuel. ]]> 2019-02-17 20:30:19 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332161833 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332163215 We would have to find a substitute for petroleum fuel that could be used with the same things we use today. It also needs to take no energy to produce, have no toxic residue and have no unexpected consequences that will force us to rebuild our way of living.]]> 2019-02-17 20:40:28 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332163215 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332163829 All the energy the earth has stored and almost all of the energy it receives every day comes from the Sun. About 89,000 terawatts (1 Terawatt is equal to a  quadrillion watts) falls on the Earth, while total usage (in 2004) was only 15 terawatts, of which 87% was provided by fossil fuels.  If we were to get most of our useable energy from the Sun, we would solve many of the most important problems Coming with energy]]> 2019-02-17 20:44:55 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332163829 kfromholt001 https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332164311 There are a number of fears about oil and fossil depletion, reliance on foreign sources of energy, geopolitics relating to the stability of a country, needs for poorer countries to more advanced ones, energy efficiency, and renewable energy sources.

Others, such as Venezuela, threaten to use oil and its related profits to develop their own country and region even more.

Many issues arise from the use of energy, greenhouse gas emissions, acid rain, climate change, dependency on depleting supplies of fossil fuels, especially from politically unstable regions of the world.

Fossil fuels are nonrenewable and are destined to run out so eventually we will have to change whether we want to or not. The emissions from the burning of fossil and nuclear fuels creates atmospheric, water, and land pollution and toxic waste.

For others, nuclear is seen as either an unfortunate reality that will be essential part of the future mix or an area that has further potential. Japan’s nuclear reactors that suffered from the incredibly huge earthquake were the older models. Nuclear experts point out that the newer designs are much more robust. ]]> 2019-02-17 21:18:03 UTC https://padlet.com/kfromholt001/ddp7tqkl9m0z/wish/332167953
