What type of engineers work in the field of sustainable energy?
What type of engineers work in the field of sustainable energy? For example solar power energy, wind energy, wave energy, water current energy. Would it be environmental engineering, civil or Mechanical?
thanks
what do you mean bbullough
The Expert answers:
Typically mechanical or chemical… But mostly engineers who work for companies that survive only on government subsidies and tax breaks… ’cause it ain’t sustainable.
Linda asks…
How much more sustainable timber cost more than timber from unknown source? ?
I am doing a survey on how much more sustainable timber sources cause, and am trying to make a statement that some of these may be green opportunists who jack up the price, riding the green wave. I need to make a fair comparison with facts to support…. please help if you know if any webpage or you have data to help me with.
Yah, is there any data to support my hypothesis that many of the suppliers are exploiting ‘green’ as their value-adding factor, their selling point?
The Expert answers:
Generally you come to a conclusion after looking at the evidence.
Michael asks…
If green energy production is cheaper and more sustainable why do energy suppliers charge extra price for th?
Despite all energy supplers being fed into the national grid,suppliers such as Eon want to charge a premium if you wish to opt for green produced electricity.i,e.wind,wave or hydro.
The Expert answers:
It is not cheaper and producers now do not care if it is sustainable, that will only matter when we use up other fuels.
John asks…
What the hell is wrong with Sustainable energy commercials?! You can’t put a windmill in your gas tank!?
One I heard started out like this…
500 billion dollars are being spent and taken out of america every year for oil…
Then it says the wave of the future is here…then it shows windmills and solar panels…WTF?!
Dose that make any since? I mean somebody who was making that commercial probably spent enough time working on it to know that you can’t go from trying to find an answer to oil to freaking windmills and solar planels!
Is this just to trick americans into thinking there IS a freaking replacement for oil?
So why show them?
The Expert answers:
Electric cars.
And cheap sustainable energy = solar and wind energy.
Hybrid cars are half way there already.
Carol asks…
Is wind power/ hydro power really a good idea?
I’ve been researching this idea for a while now, and I’d like some other opinions. Based on physical laws, energy cannot just be made. It has to come from somewhere. By harnessing wind and waves, we are taking energy from the oceans and from the air. To be clear, wind turbines slow the wind, and hydro power slows the waves. If that happens on a large scale, I think we would have a different eco-problem on our hands other than global warming. The fact that wind cannot spread pollen, or push clouds where they need to go. And the waves wont spread plankton and other microscopic neccessities, and it could alter key ocean currents on the planet. Is this a valid arguement? It seems that fission or fusion might be our only hope for sustainable energy.
The Expert answers:
They’re not a bad idea on an individual basis, but they’re not too reliable yet and shouldn’t be taxpayer funded. Geothermal energy is the best in my opinion, while it won’t give you any electricity it provides a basically free way to heat or cool your home. Where I am it gets very cold and I wish I had it here.
Don’t worry over the effects of generating power. Anything that happens as a result goes back to normal in seconds. Windmills will not slow the wind at all, just capture some of the energy while it flows by. To generate hydro power you need a dam, and they’re always built on rivers. In the St. Lawrence river there is a huge one. The company that constructed it also built ‘fish ladders’ so that marine life wouldn’t be affected in their swim upriver for spawning.
Nuclear power is still the cleanest overall and the most reliable.
