algae doesn't work. algae has to be grown in really controlled environments, because if it is out in an open pond, one bird pooping on it (nitrogen) will wreck it. the highest oil producing algae also grows the slowest- you can't get the best of both worlds, they've been trying to cross breed it for about 15 years. storage is a pain, too- what do you do with an acre of algae? it's not like crops where you sell the fruits and use the rest of the plant. it's incredibly expensive.
no, the best form of biofuel right now is biodiesel or methane digesters at farms. as far as alternative energy goes, up here, solar is by far the most effective form of alternative energy, both photovoltaic and solar hot water. after that, wood gasification is the best bet. wind is a distant fourth. at fully optimized levels, windpower is only 59% efficient, and due to turbulence, friction, etc.., we never get even close to that.
in all seriousness though, the best way for work on this is to get people to start getting off the grid on our own. PV cells should have a federal tax credit that rivals the homebuyer's. however, if you do want to really be grid free, you should invest in SEVERAL systems- solar PV, wood gasification, and maybe a small 1-2 kW wind turbine.
I don't disagree with you on Algea, early on in its infancy and needs much work. But, I am happy the industry is exploring options.
Also, I agree on your assesment of going off grid. My company sells this equipment and we have installation teams nationally. Right now, this year and next, is truly the year to purchase, while prices are still low. Good post PatGreen.
