What are the advantages and disadvantages of wind energy?
How are waves formed? Do you think wave ebergy comes indirectly from the sun? why?
How will knowing when it is high/low tide be useful to human kind?
Why is crude oil found under the seabed or under land which was once covered by the sea?
Why do fires sometimes [...]
The UK Government is promoting new generation nuclear power stations. Many environmentalists are suggesting that tidal power is a much better option.
The Severn Barrage tidal power plan is one such option. It is predicted to produce 4.2% of the UK’s electricity from the predictable ebb and flow of the tide.
How it works: Water from [...]
I dont understand this. Energy cannot be created or destroyed, right? so where does tidal energy come from? Surely it is a perpetual source of energy as the pull of water by the moon will always exist as long as the moon exists so therefore energy will always be being created?
I hope this makes [...]
Can someone tell me if I got these right?

Mine are
1) Overpopulation= this world desperately needs to curb the growth of the planet, education, birth control, only two kids per family.
2) Economy= end all corporate tax breaks, subsidies, offshore tax shelters, donation benefits, etc. spend more money on health care, education, housing, farming, environment.
3) Environment= reduce greenhouse emissions, cut oil use by 25% [...]

Like toilets, for instance; with the new low flow, high efficiency, auto-flush, don’t you find that you end up flushing more often? Not like the old days when you push that lever and EVERYTHING goes down no matter what! Your waste, your wallet, your hamster – whatever! And what about toasters. My parents had a [...]
