Q: How can anyone be against clean, non-renewable sustainable energy?

A: People who make their living from fossil fuels. ..

Q: How should I go about an engineering career in sustainable/renewable energy?
I’m from the UK but I’m thinking about studying at an Australian University because the joint degrees seem to offer a lot of flexibility, but I could do with some advice on recommended courses?I’m thinking about engineering with some kind of science, and maybe astronautical engineering too?
Sorry it’s so vague, but I’m kind of lost!

A: If you want to design, install and maintain the wiring and electrical supply, focus on electrical engineering. If you want to work on wind, that is mechanical engineering, but it’s pretty much going to top out at 5-10% of a nation’s supply, so you might limit your growth. If you want to work at combustion fuels, go chemical engineering. There are sub-categories of these (aeronautical, fuels, and others), but they area so close it means 2-4 different classes, and you might limit your marketability.

All engineering comes with a lot of “some kind of science”. You tend to finish within 2-4 courses of a degree in physics, maybe math, and chemistry (if you study chem engineering), so that is a given

Q: What is the difference between renewable and sustainable energy sources?
Can something be sustainable but not renewable?

A: Renewable energy is energy generated from natural resources—such as sunlight, wind, rain, tides, and geothermal heat—which are renewable (naturally replenished)Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.

Each of these sources has unique characteristics which influence how and where they are used.

Sustainable energy sources are most often regarded as including all renewable sources, such as biofuels, solar power, wind power, wave power, geothermal power and tidal power. It usually also includes technologies that improve energy efficiency

Q: I have an idea for renewable and sustainable energy that will change the world, what should I do?
I need help.
I am not going to tell you me idea, then you would steal it.

A: write a letter to your congress person, explaining what it is and ask for a meting. If that doesn’t work you can get the idea patted and take it to a nonprofit environmental organization.

Q: If i want to work with creating renewable and sustainable energy what major should i take in college?

A: you could do environmental studies (its for the environment), engineering (maybe some green buildings), or artitecture.

Q: Which would you prefer, drilling for more oil, OR migrating over to a sustainable renewable energy source?

A: Nuclear power, and geo-thermal are my favorites. So that is what I would prefer we do.

Q: Have we developed a sustainable/renewable form of energy yet that will allow us to reach the stars?
Is anyone out there working on a fusion/fission or other technology that is self-regenerating and will allow for fast, efficient space travel for humans?

A: simply no. it is not possible to have a perpetual motion machine because there will always be some energy lost. fusion is fantastically efficient in terms of mass to energy and has none of the radioactive problems of its fission counterpart. however it still uses up fuel and you cannot then reuse this. also the technology at the moment uses more energy than it produces meaning that this is still quite a long way off. this is perhaps the most realistic way of powering the spacecraft that you appear to visualise however there is still the problem that it cannot go fast enough and unless a way is found of bending space itself you cannot go faster than the speed of light or indeed reach the speed of light so the answer is no at the moment and no for the foreseeable future.

Q: how is the use of renewable energy sources important in achieveing sustainable development?

A: There is only a limited amount of oil, gas and coal in the world. Eventually we’ll run out of stuff that’s economic to extract. So renewable sources will keep providing energy when that happens, ie it’ll sustain us.

Also, renewable energies almost all emit far less in terms of pollution and radiation. Some coal plants emit up to three times the radiation of nuclear power stations and other air pollution kills tens of thousands of Americans every year, and costs billions in healthcare. They also emit far fewer greenhouse gases, contributing less to global warming – minimising global warming will be good for humanity because that will help sustain Earth’s capacity to support us (eg if rising sea levels and spreading deserts cut down the land we can use, that’s not very sustainable!)

Finally, it helps energy security. Countries won’t be as likely to go to war with each other for wind and Sun in the same way they do for oil & gas.

Q: What is an example of an energy source that’s sustainable but not renewable?
I don’t think nuclear energy is generally classified as sustainable because Uranium ore supplies are limited and non-renewable. But could you give me any others? :)

A: When you say an energy source is ‘renewable’ it means that although the quantity can be diminished, it can be easily replenished (i.e. quantity is not finite like petroleum or uranium). Biofuel is renewable because it comes from an organic source (plants/animals) which can be grown in crops or farms. Non-renewable sources cannot be artificially produced on a large scale, like petroleum and minerals.

When you say an energy source is ’sustainable’ it means that you can tap into it in a practical, cost-effective way now and in the long-run. For that to happen, the source should be cheap, plentiful and/or renewable. If ‘long-run’ for you is 30-50 years, then petroleum is sustainable because it is stable in the market. It’s not renwable, but to a certain degree is sustainable. If you’re looking longer than 50years, then perhaps solar energy becomes a good candidate. It’s not sustainable NOW because of the prohibitively expensive costs, but several years from now it will be more affordable. Same can be said about energy from wind, hydro and ocean currents (too expensive now to replace petroleum-based fuels, but price will go down in the future). So all these alternative fuels are NOT sustainable, at least not yet.

Nuclear power is much more efficient than petroleum-based power and yes, it is not a renewable source. For the output it produces, it is much more cost-effective than solar, wind, hydro and ocean current sources.

Q: Who is doing renewable energy education? How are you accomplishing the task? What are you focused on?
I am researching the current energy and renewable energy issues facing the world. The task is very extensive and complicated. Each region has renewable energy opportunities that can be important to environmental issues, economic development, and social needs for all humans. Government agencies, industry, agriculture, educational and research organizations are focused upon massive research efforts. This seems to provide a way to share information, thoughts and ways to help people to improve our lives by conserving energy, find alternative energy resources and realize that fossil fuels are depleting and non-renewable. Can renewable energy be a way to produce additional energy? Networking can provide valuable information to further the advancement of changing habits about energy. I am a farmer with a background in sustainable energy and educational degrees in agriculture. A sustainable energy for industrial and developing countries can improve the quality of life of all human beings.

A: wow – i’ve already done my college work… sorry – i don’t feel like doing yours.

Q: Wind Turbines > Great renewable energy source or just a way for landowners and local government to make money.?
I am all for renewable sustainable energy alternatives such as wind farms, light towers,solar fields and various tidal and thermal alternatives.

I have studied wind farms in my area and across the U.K

I have found that wind turbines generate very little electricity. In fact of all renewable energy sources these are the least energy efficient and the least cost effective.

Our Government here in the U.K. offer huge cash subsidies to land owners who install wind farms on their properties. The land owners also make a huge profit from selling the plots to prospective manufacturers of wind turbines who then build on these plots and sell the electricity back to the national grid. who then in turn sell it to you the people.

Lots of money is being made by land owners and manufacturers of turbines and also by energy suppliers.

We import huge amounts of food every year and yet here daily good farm land is being sold by its farmers in order to make money.

There are a million questions to answer and a million reasons why.

share your thoughts please………………………………………

A: I’m more inclined towards solar power as an effective means of energy. I believe our sun can provide all the energy needed for the entire planet. I mean, it’s there for very good reasons.

Q: Would a $100 Billion investment be enough to produce sustainable energy?
I was thinking would an investment of one hundred billion dollars to research cheap, clean and renewable energy be enough?

A: That would be a start and it is a step in the right direction. Energy use starts with the individual. Before power plants people produced their own fuel such as firewood and candles and raised their own transportation. (Horses, Mules, Walked). Don’t wait for the government to go green. If each building in the USA was equipped with solar panels and in wind prone areas wind turbines our fossil burning plant emission would be reduced by about 85%. Don’t wait for the government to go green you be the 1st in your neighborhood to leave the grid. Great question.

Q: Is nuclear energy resource is a clean,cold and sustainable energy technology to fueling the future?
How would u challenge to innovate alternative energy technology to renewable energy resources at cheap price?

A: Nuclear energy is not “cold”, I am not sure what you meant by that. The whole principle of how muclear energy is used to generate electrcity relies on the fact that it gives off a lot of heat.

It is also not too clean either. The depleted nuclear waste posses a problem of where to dispose of it. It will stay radio active for hundreds of thousands of years, so whereever you put it it needs to be out of the way and secure. Right now, the government is planning to store the stock piles of nuclear waste deep underground under Yucca Mountain (in Nevada I think), but there is a lot of debate over this.

As for sustainable, perhaps not in the long run. There is only so much fissionable material on Earth, it will run out eventually just like fossil fuels. A more long term nuclear energy sourse would rely on fusion, not fission, but this has yet to be practical.

Q: What are some sustainable living options? – and some extended details please?
I am doing some homework on designing a poster for Technology Class. I just need some help on what I should choose, they all seem good. I need this ready for the 31st of March. Thanks! And if you cannot answer this question, then you could probably try to answer my other question about using sustainable or renewable energy in our lives :) Thanks!

A: 1. Make compost from all vege waste.
2. Install a composting toilet
3. Grow your own food using the compost.
4. Fully insulate your house
5. Add solar gain to your house like a conservatory
6. Re-use as much as possible
7. Recycle what you don’t re-use.
8. Turn your car into a glass-house to grow tomatoes etc.
9. Ride a bicycle
10. Collect rain water
11. Use water sparingly
12. Go to bed at sunset and get up just before sunrise
