Whether the discussion turns to replacing coal - fired power
plants with wind turbines and using electric cars instead of gas - driven SUVs, converting industrial agricultural practices to organic permaculture, or reversing the decline of ocean life though international regulations, it is an article of faith in the reform movement that we know what we need to do and all that's lacking is a sufficiently visionary leader to put more planet - friendly solutions in place.

wind turbines and power management systems.
That's because a working electricity system fueled mostly by
wind turbines requires additional massive costs that a fossil fuel system does not: huge excess capacity (perhaps 300 - 400 %) to deal
with conditions of light
wind; gigantic batteries to store power for conditions of no
wind at all, which can persist for days; extra transmission lines to bring electricity from windier areas to the rest of the country; and finally, an entire array of fossil fuel back - up
plants for those occasions when the
wind doesn't blow for a week and the batteries are dead.
Contrary to the claims of some critics, today's research shows that the hidden emissions due to building
wind turbines, solar panels or nuclear
plants are very low, in comparison
with the savings from avoiding fossil fuels.
