How can you talk about bio fuels and not mention hemp? It's by far the best source for bio fuel. That tree they were talking about grows in 3 years. Hemp grows in 30 days.

Some good points are made, however many points are one sided and naïve. The presentation on diesel power and fuels is good, but see the movie ‘Windfall’ to learn what it’s like living near 400 feet tall wind turbines. Implying that intermittent energy sources (such as wind and solar) can eliminate coal and nuclear is silly without adequate means of storing massive amounts of energy. Blackouts and brownouts are not acceptable. Implying with certainty that global warming exists, is man made, and is devastating overall is not fair. Suggesting that we need cool rooftops in cold climates (like New York) is also foolish. Politicians in some major cities now require cool roofs despite the fact that far more energy is spent heating their buildings then cooling them. I wish you could have looked into the potential of fusion energy, too, but that form is not quite ready to replace our fission plants. Watch this film, but know that there is a lot more to these issues than what is presented.

Very irritating and obnoxious. Made me edgy. Time to move on. Poor documentary.
