Alternative Energy Sources

Can anyone please tell me of one form of energy the enviromentalist will not attack?
I guess solar power is now evil.
Wind power kills birds.

Wind power doesn't kill birds. The towers are hundreds of feet high and the wind farms are cleared of undergrowth - there's nothing to attract birds to the site.

It's not about CO2 with these people. It's not even about pollution. It's about lifestyles. They prefer a David Kaczinsky lifestyle and it's not enough for them to live it, they need to impose it on us. They see humanity as a pox on the earth.

“If you ask me, it’d be a little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it…” – Amory Lovins, Rocky Mountain Institute.

“The only real good technology is no technology at all. Technology is taxation without representation, imposed by our elitist species (man) upon the rest of the natural world”
– John Shuttleworth, founder of Mother Earth News.

“Isn’t the only hope for the planet that the industrialized civilizations collapse? Isn’t our responsibility to bring that about?” – Maurice Strong, Secretary General 1992 UN Earth Summit

“Everything we have developed over the last 100 years should be destroyed.” – Pentti Linkola

We must make this an insecure and inhospitable place for capitalists and their projects…. We must reclaim the roads and plowed land, halt dam construction, tear down existing dams, free shackled rivers and return to wilderness millions of tens of millions of acres of presently settled land. —David Foreman, Earth First!

The extinction of the human species may not only be inevitable but a good thing….This is not to say that the rise of human civilization is insignificant, but there is no way of showing that it will be much help to the world in the long run.
—Economist editorial

We advocate biodiversity for biodiversity’s sake. It may take our extinction to set things straight.—David Foreman, Earth First!

Phasing out the human race will solve every problem on earth, social and environmental.—Dave Forman, Founder of Earth First!

If radical environmentalists were to invent a disease to bring human populations back to sanity, it would probably be something like AIDS. —Earth First! Newsletter

I suspect that eradicating smallpox was wrong. It played an important part in balancing ecosystems.—John Davis, editor of Earth First! Journal

Human beings, as a species, have no more value than slugs.
—John Davis, editor of Earth First! Journal

“Phasing out the human race will solve every problem on earth, social and environmental”– David Foreman, founder of Earth First!

“If there is going to be electricity at all, I would like it to be decentralized, small, solar-powered”– Gar Smith

“The only hope for the world is to make sure there is not another United States…”– Michael Oppenheimer, Environmental Defense Fund

“Man is always and everywhere a blight on the landscape.”
– John Muir, founder of the Sierra Club.

The right to have children should be a marketable commodity, bought and traded by individuals but absolutely limited by the state. - Kenneth Boulding, originator of the "Spaceship Earth" concept (as quoted by William Tucker in Progress and Privilege, 1982)

We have wished, we ecofreaks, for a disaster or for a social change to come and bomb us into Stone Age, where we might live like Indians in our valley, with our localism, our appropriate technology, our gardens, our homemade religion — guilt-free at last! — Stewart Brand (writing in the Whole Earth Catalogue)

Human happiness, and certainly human fecundity, is not as important as a wild and healthy planets…Some of us can only hope for the right virus to come along. — David Graber, biologist, National Park Service

The collective needs of non-human species must take precedence over the needs and desires of humans.—Dr. Reed F. Noss, The Wildlands Project

If I were reincarnated, I would wish to be returned to Earth as a killer virus to lower human population levels.—Prince Phillip, World Wildlife Fund

We, in the green movement, aspire to a cultural model in which killing a forest will be considered more contemptible and more criminal than the sale of 6-year-old children to Asian brothels.—Carl Amery

Every time you turn on an electric light, you are making another brainless baby.—Helen Caldicott, Union of Concerned Scientists

To feed a starving child is to exacerbate the world population problem.—Lamont Cole

Cannibalism is a "radical but realistic solution to the problem of overpopulation." — Lyall Watson, The Financial Times, 15 July 1995

This is an anti-human, anti-progress, anti-civilization movement. The only thing that has changed is the pretext for their argument:

This cooling has already killed hundreds of thousands of people. If it continues and no strong action is taken, it will cause world famine, world chaos and world war, and this could all come about before the year 2000.—Lowell Ponte in “The Cooling”, 1976

If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder by the year 2000. … This is about twice what it would take to put us in an ice age. —Kenneth E.F. Watt on air pollution and global cooling, Earth Day (1970)

that is, how a scientific calculator works when its battery power is totally down?how it works when it is shown in sunlight for sometime?please give me the mechanism involved in it.

when batt not available the triac is used so the base power switches to solar cell and there if it gets energy it emmitts power to 7-segment and again ur calc is on solar batt. when u replace battreis again the triac actives through batt power.

I think its Very Late to even think about it "WE SHOELD HAVE DONE IT"

that would be great!

If you work out the solar irradiation per square meter, you’ll find that there is more than sufficient energy reaching the Earth… the problem is finding an efficient, cheap way to harvest and store it. The other issue is polar regions that might undergo months at a time of darkness.

On a not totally unrelated topic: There’s enough harvestable wind energy to power the world six times over. At the moment though, wind turbines convert about 14% of the total energy in the wind flowing through them. Compare this to coal-fired power stations, which operate at about 30% efficiency: Until coal becomes too expensive to use for fuel, governments will refuse to implement wind and solar on a wide scale. (Though taking into account the environmental cost and long-term payback of renewable sources, they’re worth it now!)

Most houses have solar panels (not photo-voltaic panels) to heat water.
Very few (maybe a few hundreds) have their own photo-voltaic panels to generate electricity.
There's an experimental solar power-plant in Weizmann Institute in Rehovot, and there's a new and larger experimental solar power-plant in Rotem industrial zone in the Negev.

I mean, i dont know too much about the country, but i know they have a lot of land that can be extremely hot.

So are they working on using solar energy? if not, why not? thanks

Some houses in Australia do have solar power, But the probem with this is that it cannot be depended upon. When the sun is shining it is fine, But even in Australia it is not sunny all the time. When it is cloudy and raining the solar panels do not produce energy very well. Here in Perth it has been raining most days for the last 10 weeks or so.

On good days solar powered houses can sell spare electricity to the local electricity company to be taken back into the power grid.

The other factor is the cost of setting up the solar powered system - about say $20,000 to set up in a house.

Answer my question.

Definitely, it will depend on the location. Many areas are definitely suited for solar such as deserts as some have mentioned. In Austin (Texas), where sun is common and plentiful, many houses have solar panels that either minimize or eliminate their need for power from the "power grid".

Wind power is also an excellent option in areas that are suitable for it. 20% of Denmark's power is provided via windpower. This is another technology that is coming into its own, with all of the changes and increased focus on greener lifestyles.

I don't understand what the person who kept mentioning oil as a renewable resource meant. It will surely be renewable once we've used up all of the raw source, but it took (and would take) millions of years to produce in the first place, so unlike trees, wind and solar power, it isn't really feasible to consider as a renewable resource.

ok here it is ..i need to install solar panels on my roof and i have appliance that need 220w. of electricity , how can i do it and who does them?

I’d suggest going to the website below, finding someone in your area who has installed a lot of solar arrays, and asking them for a price quote and installation details.

It’s impossible to size the unit based on the info that you’ve given us. Because the sun only shines some of the time, you’ll need to store some energy - if your 220W appliance ever runs when the sun isn’t out. And the amount you need to store will depend on whether your appliance runs continuously, or cycles, or whatever.

Good luck.

active and passive
cost effectiveness and return on cost
any government rebates???
cost per kilowatt hour/megawatt hour
explanation of what it is and how it works
advantages and disadvantages
what can you power with it
individual panels or big panels

1. cost well it depends on how big the solor pannels are.
2. no.
3. it really depends on what the sizes are and what things are
included.
4. when a solor pannel is outside the sun shines on it. The
pannel then soaks up the heat energy and converts in into
what ever energy that you wish. Basically it takes the sun
energy (or heat energy) and changes its chemical ballance
to another form of energy like electricity. It's a cheap way
to use electrical things without a bill (LOL) !!!!!!
5. an advantage is that it's a good way to conserve energy
and it's environment friendly. Some disadvantages are
that if there's no sun that day then depending on how much
energy your solor pannel can hold you might not have
enough energy that day.
7. you can power almost anything using it.
8. i prefur big pannels but if you're not much of a big spender
than i would go with individual pannels.

i have the idea of building a complete self contained house and solar power seems to be the best way to go

This site will give some ideas, and also the most efficient appliances for a solar powered home.
