Your Questions About Renewable Energy Definition
Robert asks…
What are some difficulties in achieving sustainable development?
Definition: Sustainable development is a pattern of economic growth in which resource use aims to meet human needs while preserving the environment so that these needs can be met not only in the present, but also for generations to come.
Why is it difficult for humans to achieve sustainable development?
And why?
admin answers:
You clearly haven’t bothered thinking about this at all:
– we don’t recycle 100% of all metals, so any metals you use will not be available for future generations to use. So, by your own definition, you can’t use any metals.
– once coal, oil, or natural gas is burned, it can’t be recycled, so any coal, oil, or natural gas you use to make anything, to transport what you make, or to transport the materials will not be available for future generations. So, by your own definition, you can’t use energy that comes from coal, oil, or natural gas.
You can argue that energy comes from the sun, from wind, or from water is O.K., but you still have to build the power plants to use those energy sources and that isn’t O.K.
Etc.
– there are resources that are theoretically renewable, but we are already cutting down trees faster than they grow back, so wood, lumber, etc. May be theoretically sustainable, but in practice, using them is not sustainable.
The bottom line is that we have too many people using any and all resources at far too great a rate to be sustainable, so anything additional you do is by your own definition, not sustainable.

Now you can cheat in many ways: change the definition of sustainable so that it becomes feasible; pretend that advancing technology means that in the future people will be able to do anything with whatever they happen to have left over (isn’t magic wonderful?) so it doesn’t matter what we leave for future generations; etc. Or you can admit that sustainable development is an oxymoron and work toward other goals.
Sandy asks…
What is the definition of Visual Pollution and give some examples on how to prevent it…..?
I’ve been looking for a definition of this for hours!
thank you.
admin answers:
As the saying goes, “beauty is in the eye of the beholder.” Visual pollution is going to have different meanings to different people. Most people would agree that excessive billboards are unattractive, but some may see skyscrapers as ‘visual pollution’ (spoiling the once natural landscape), while others may love viewing their architecture. Wind Farms (large areas covered by many wind mills) would be another example of visual pollution to most people. But then we are faced with the question ‘is it worth it for the renewable energy?’
How to prevent it? Stop building. But that’s just my opinion; some people may not like the looks of trees and fields and prefer building and signs.
Here’s some info. From Wiki:

Your Questions About Sustainable Energy Systems
Mandy asks…
How much would it cost to build a very sustainable home?
so i was just thinking of what kind of home i’d like when i grow up and i obviously want one that gets energy through renewable resources such as solar power, wind, and geothermal maybe. my question is how much it would be to build a new house with all this installed and also with good insulation and also the house be a passive solar system. and if someone could answer this too, is it possible to build a house anywhere you want? and also grow food by yourself?
admin answers:
Yes, you can build a house almost anywhere you want and you can grow food by yourself; but, this all depends on your level of dedication to those particular tasks as they will require a great deal of time and fortitude. As far as the green house goes, you can do some research on people who have built green houses. From what I have seen you’ll spend about 30% – 50% more on a green house versus a regular one.
George asks…
What are the most counterproductive doings of our society?
I am trying to write a thesis and look for inspirations. Here are a couple I have:
1. Manicured lawns instead native wild flowers – responsible for huge enviromental damages and sustaining large amounts of illegals.
2. Cars and Suv’s with Motor technology from 1930, instead modern motors with high mileage – huge enviromental impact, sustains arab terror, uses non renewable resources, makes Detroit incapable of world wide competition.
3. Clear cutting instead of selective cutting – not sustainable, huge enviromental damages
Can you add one? Thanks!
admin answers:
Runaway consumerism, Chinese imports of everything from US flags to rubber monster toys, rampant energy dependency while firing up hair dryers and moving to hotter climates to increase air-conditioner / comfort dependency, ‘out-sourcing’ of consumer products, RV and other gas guzzling automobiles, distributing free commodities and providing cradle-to-grave dental and health care benefits to Native American reservations where they frequently are merely supplements to personal wealth because of tribal casinos, encouraging tribal members to stay on reservations by and assuming responsibility for themselves by providing financial incentives through reservation grants [while the tribes claim ‘sovereignty’ on those reservations]
Placing our resources into building prisons, proliferating court personnel, and attorney welfare systems, more police, equipment and violation of property by pursuing a War on Drugs and prosecuting victimless crimes that’s only assured higher prices and more drugs on the streets while corrupting the criminal justice system.
ICC discouraging rail transport by setting uncompetitive freight-hauling rates, while encouraging long-haul trucking [to pay for the Interstate Highway system, initially, and later to pay for the damage trucks do to the highways].

Your Questions About Renewable Energy Group
Maria asks…
What are the different viewpoints on the use of fossil fuels?
Hello, I am struggling to find viewpoints of the following people:
– Environmentalist
– MEDC (More Economically Developed Countries) Governments
– LEDC (Less Economically Developed Countries) Governments
– Energy Companies
– Consumers
– Oil Producing Countries
– TNC’s Shell? BP?
Can you please give me a few websites which:
-explains why different groups have opinions on the consumption of fossil fuels
– says whether they think fossil fuels should be used in the future and given reasons why
(considers advantages and disadvantages of using fossil fuels vs renewable energy sources)
admin answers:
Smart: They’re useful, effective and can be used responsibly.
Hypocrisy: You shouldn’t use fossil fuels. I’d like to talk more, but I have to put my family on two different private jets to fly to Hawaii for a 17 mllion dollar taxpayer funded vacation. (You Americans have just gotten soft and lazy.) Electricity prices are going to skyrocket to when I drive coal out of business.
Idiot: We should all ride bicycles and not use any oil at all. (Oh… You mean my clothes, computer and bike tires are made of oil…. Oh.)

What is a good Current Event to give a speech on?
So my partner and I are assigned to create a collaborative speech on a current event/ issue. The speech needs to have some kind of debate within to allow group discussion after. For example We were thinking of doing Renewable Energy Sources but we couldnt find anything to argue against it or something,
Thanks for the help!!
admin answers:
With renewable energy source here are so cons: Cost is to high, not enough technology available to make it worthwhile, how long will it take for it to be profitable, and not enough big business is behind to make research worth the effort.

Your Questions About Sustainable Energy Without The Hot Air
Ken asks…
Where is harder to survive..?
Northern Canada/Russia (with lots of cold and snow) or a desert in Nevada?
Assume that there is no countries or cities around, you are the only human in the world and you have to survive by yourself. I am talking about lifetime sustained survival. Not just survive until you get out kind of thing.
PS: I didn’t use a desert in Africa like sahara because obviously there is absolutely 0 chance of sustainable human life.
admin answers:
The Sahara desert has been home to thousands of people for thousands of years. So has the Namib desert and the Kalahari desert where the bushmen have hunted very skillfully for many generations and they eat well.
The Nevada desert can feed you too if you find the skills to get the food it harbours.
Learn some biology. Then you can eat. Learn geology and you can find water. And oil.
The driest desert in the world is the Atacama. It’s beautiful. I’ve been twice. It’s got places where no rain has fallen for more than four hundred years.
But it hasn’t got the driest air in the world.
That’s in Antarctica where water is frozen out of the air and where scientific instruments, especially for infra red measurements which get ruined by water vapour in the air absorbing infra red, are stationed in the scientific research stations at Ross Island and around the South Pole.
It’s easy to look it up. ..Antarctic Research Stations.
The driest air in the world lays over a huge sheet of ice and snow…frozen water.
Cold places give you water but more importantly they demand more in supplies than hot places. It takes more energy and more materials to heat things than to cool them.
Without enough heat you’re soon dead. Providing it and keeping it is costly in materials and clothing..
Deserts get cold at night, even the Sahara. You get a break from the heat and bright Sun.
You can burn camel dung or other dung and dried grasses to get enough heat for cooking. That’s all the heat you need.
Move when it’s cooler in the morning and evening and get shade under a high tent or in the shadow of rocks during the hottest part of the day.
You can cross the Sahara with a lighter load than for crossing Siberia.
Both places you need wildlife to live on or take your own animals. Move to where they can eat so you can keep them alive.
The reindeer herders in the far north of Finland do that, where a warm night in winter is -20C.
Reindeer provide milk and meat, furs for clothing and shoes, tents and sleeping mats, and bone for knives and ornaments.
Sami people have been living in the far north for more than two thousand years
http://norskfolke.museum.no/en/Stories/Set-1/Sami-baptismal-boots/ .. .
Http://www.suite101.com/content/the-sami-of-the-north-a222034 . . . .
In the Sahara camels and goats and sometimes sheep provide the milk and meat, and give wool for cloth to make clothing and tents and bedding rolls, and leather for shoes.
Nomads move to where the grazing is best, in the Gobi desert, and in the Sahara and Namib deserts.
In both cold and hot places you can trap birds and small animals.
Hares and arctic foxes in the far north…or lizards and snakes and the few small mammals that live in the desert..
Many cold places have rivers with fish, and by the coast the sea provides food as well….seaweeds, molluscs, fish and seals.
Desert or frozen tundra…you can live in both and thousands do.
In desert you can still get water.
Hang a fine net to collect the dew. Some plants do that.
Dew collects on the hairy leaves and stems overnight in desert air and provides water for birds and small animals. Be up early enough or it’s gone down animals throats or into the plant or back up into the sky.
That’s where the net idea came from….hairy plants that collect water from dew.
Nets are also used to collect water from fog in remote mountains,and in deserts eg in Chile.
Http://news.nationalgeographic.com/news/2001/11/1101_TVdesertbeetle.html . . . . . .
You can dig condensation pits or condense water from plants.
Http://www.wikihow.com/Make-Water-in-the-Desert . . .. ..
You can dig into the desert where the signs tell you water lays underneath. When it’s close enough to the surface wind-blown seeds take root and you get an oasis.
Thousands of people have lived in deserts and frozen tundra for thousands of years, long before modern equipment existed like expensive water reservoirs for backpacks instead of far more useful and versatile water bottles which keep Arabian nomads alive in the fierce desert heat but are too simple for ‘must have the latest’ techy walkers.
Learn to live where you are and then you can live. Generations long past past did that quite well enough for the current populations to be there……
Have fun
Desert walks….

Mandy asks…
So why isn’t nuclear power being developed if global warming is such a threat?
Sustainable Development Commission statement on nuclear power: http://www.sd-commission.org.uk/presslist.php/51/nuclear-power-wont-fix-it
Further to my question on Nuclear Power (yes or no) many AGW proponents pointed out that they were in favour of it, or at least had no serious objections.
But if that’s at all representative, and if AGW is such a threat, why isn’t nuclear power being actively pursued? Take the UK, pretty much all ‘Green’ groups vehemently oppose it. The government is being advised on it’s energy policy by a commission which it set up and appointed Jonathan Porritt to head (ex-Greenpeace anti-nuclear campaigner).
It’s obvious that – for the short and even medium term – renewables and energy saving won’t cut it. See the calculations at www.withouthotair.com
I ask because it seems that both warmists and sceptics seem to agree on nuclear. If that’s at all representative of the views of most people then why aren’t we actually doing something rather than planning another massive conference in some far-flung location?
admin answers:
Because a lot of the people who are in charge of solving global warming are either:
a. Completely ignorant of the fact that wind and solar can’t solve global warming.
B. Heavily influenced by fossil fuel interests that would be hurt if nuclear power took away their market in the process of solving global warming.
B(2). Influenced by the fossil fuel unions who don’t want to lose their power (the workers don’t have much to worry about though, the time it’ll take to switch to nuclear will be more than enough for retraining and a lot of them would probably end up working at a vastly safer nuclear plant anyway).
C. See global warming as a means to force people to use less energy and return to ‘simpler’ times whether the population wants it or not (never mind that most people would choose global warming over what the greens want).
D. Are afraid of losing the votes of the anti-nuclear kooks.
The green groups should not be thought of as environmentalists, for the most part they are urban trendoids who don’t really have a clue about the environment but want to feel good about doing something. There’s also a big focus on appearance for the greens and probably a bit of residual Christian morality making a virtue of sacrifice.
The views you get here probably aren’t representative of the majority of the population although the anti-nuclear movement is in decline, they should be almost gone within the decade.
The scientific community probably hasn’t done enough to tell the public and politicians what the scientific consensus on nuclear power is and why renewable energy isn’t going to be able to do what we need it to.
As for _Sustainable energy without the hot air_, that is probably a bit (or maybe a lot) optimistic for renewables although it covers the UK which has a relatively high population density, other countries might be able to get all their energy from renewables assuming that enough decent energy storage systems could be built (we don’t really have that though, pumped hydro is the best we’ve got but we don’t have enough suitable sites for it).

Your Questions About Renewable Energy Content
Helen asks…
Is the carbon tax really for preventing climate change?
So here’s what currently baffles me; if climate change is being used as an excuse to implant a new taxation on carbon, why oh why did the Bush administration try to deny its existence for so long?
Surely big oil, which has substantial influence in world governance, would be afraid of carbon taxing, and indeed the ensuing encouragement of renewable energy, over which they would have much less control (read; money). Or will they simply make sure to take over the emerging “renewables” sector too?
admin answers:
No it is not for preventing climate change. 1. We cannot prevent climate change. 2. It is to punish industrial nations and to lower the standard of living around the globe.
Here is a good article that discusses the science behind point 1.

John asks…
Do business leaders in renewable energy lack vision?
I the panel session at a conference yesterday I asked the chairman of a new bio-diesel plant how he saw the industry developing over the next 30-40 years to take the market share of renewable transport fuels from insignificant to 95%+ to replace fossil fuels when they run out. The response showed no interest at all in expanding beyond a small regional market. Is this a common attribute, or are there visionary business leaders that are thinking big picture and have plans to replace fossil fuels?
admin answers:
30-40 years is to far ahead.
Peak oil will come within this decade.
When that happens, the energy industry will be turned on it’s head.
It’s not impossible that in 20 years, hydrogen fusion will become available.
That would completely upset the apple cart.
In a good way, mind you.
Any alternative source today needs to focus on making a profit in order to not go under.
Once they’ve reached that, then they can look farther ahead.
Also, i’m just not sure about bio-fuel.
I have seen estimates that would indicate that it would be possible to be a significant part of our energy.
But it just doesn’t seem to me that we’d be able to get that energy content from plants, in a reasonable acreage, and still produce the food that we’ll need.
Jet planes will likely need something like that.
Long haul trucks would as well.
Maybe trains in sparsely populated areas of the country.
But i’m not sure about most other transportation.
