Advantages of Green Energy
Author: Kaci Elise
Green energy is defined as the energy that does not affect the environment and comes from renewable sources. It is also referred as sustainable energy. The production of green energy usually includes technologies that improve energy efficiency. Examples of renewable sources of green energy are wind, sunlight, water, geothermal, hydrogen, biomass, and waste materials. Below are some of the advantages of green energy:
1. Helps in mitigating global warming. The daily use of fossil fuels has led to global warming. In the United States alone about 85% of their energy consumption comes from fossil fuels. If extracting of energy from fossil fuels continues, the earth surface will get warmer in few years time. However, green energy offers a safe way to use and generate energy. It will not damage the environment at the same time can help in mitigating global warming.
2. Prevents acid rain generation. With today's environment, earth's air also comprises of many pollutants such as sulfur dioxide (SO2) and nitrogen dioxide (NO2). These gases are produced when fossil fuels such as coal and petroleum are used by industries, vehicles and power plants. The acid rain is formed when water vapor combines with SO2 and NO2. But with the use of green energy, dependence on fossil fuels will decrease thus decreasing the probability of having acid rains.
3. Improves environmental protection. The usage of fossil fuels such as oil comes with many disadvantages and that include oil spills that causes environmental disaster. Just take for example the oil spill in Gulf of Mexico, hundreds of marine wildlife and ecosystems have been ruined. It could have helped in conserving our flora and fauna if the world dependence on oil has been stopped long time ago. The use of green energy greatly helps in conserving our environment since it does not cause any pollution to the environment.
4. Cost effective and improves energy efficiency. Energy from renewable sources is more efficient and cost effective compare to coal and oil power plants. Some people argue that green energy facilities are expensive to build, but these facilities only requires less maintenance thus you can still save a lot by investing on green energy facilities.
5. It is renewable. Green energy can be created continually and can be used repeatedly. The renewable sources of green energy are created continually by nature thus it's unlimited unlike fossil fuels that will eventually be used up entirely.

DemoLibs? Are there any new Green Energy Technologies on the horizon that work?
So far none are working very well…A couple of years ago I saw a show about low cost/high efficiency flexible solar cells that were supposed to revolutionize things, haven’t heard or seen anything about them since…
There is NOTHING that is ready to hit the consumer level. This is garbage and they have nothing.
Is Applied Physics a good field to study for green technology and alternative energy?
How employable would someone with a Doctorate in Applied Physics be, in the alternative energy/green technology field?
What kind of jobs would such a person have?
YES! ABSOLUTELY!!! The application of physics is what inventors practice on a daily basis. As for the type of job, that would mainly be design engineer. One thing that you can do is think out of the box. You should delve into the practice critical thinking. You can do is apply the use of neodyme magnets for turning a generator, ask yourself questions such as “what would this do in a vacuum environment”? Will it increase the energy output? What natural kinetic energies can be used to turn a generator? What size unit would power a home? Is there any electronic pollution and if there is can I convert that pollution into etheric energy?
what are the colleges/universities offering M.SC in renewable energy/green Technology courses in india?
I am a B.SC computer science graduate. I want to do post graduation in energy related studies. for example green energy technology/ Renewable energy/ sustainable development/ alternative energy.
I can not go for M.Tech because I am B.SC not B.Tech/BE I am tired of searching internet and Google.Thanks in advance.

Financing & cultural challenges to getting more green energy adoption?
I’m curious to hear what some of the financing & cultural challenges are to getting traditional energy companies to adopt green technologies? In particular, I know that many green energy sources require significant up-front investment today to capture the benefits of potentially grid-parity kwh production in the future.
How does financing work in the energy industry today around the world and is it possible that the way energy production is financed might hinder large investments?
Also, what some of the cultural challenges to green adoption? For example, are $/Watt and $/kwh even the right metrics to use when thinking about the economics of adopting green technologies?
Every source of energy takes huge up front investments. You can’t produce electricity with coal unless you build the plant. The government has subsidized most forms of energy, so I don’t see any differences between dirty energy and clean. The only real difference is wind, solar, tidal etc, won’t be held hostage by suppliers or market conditions. We just need more people like T. Boone Pickens to see there are ways to make money off of the technology and it will happen.
Culturally, the challenge is to show people we can continue to live a comfortable lifestyle and conserve energy. We can solve a lot more problems by cutting back on demand than rushing projects to meet demand.
Should the U.S. government sell green energy bonds to help fund green energy technologies ?
Private industry has not moved forward and I don’t know that want private industry to be in charge . They answer not to the American people but to share holders. We have seen how this plays out and it is not pretty. Let the American people invest in a solution with our government as this is a national security issue . Cap and trade must pass and the threats that corporate America makes on the U.S. citizens (if you regulate us we will punish you by raising rates.) are the reason we want our government to be in charge of energy in the future. I do not want to be pay for a bottom line especially when it is detrimental to the well being of our nations future.
@obamabinbiden you deserve what fate has in store for you, but I am tired of paying for the ignorance of you and tgose like you. If you want to be beholding to someone else’s profits that’s your choice.
