DailyDirt: Alternative Energy

from the urls-we-dig-up dept

Developing more sources of renewable energy to help replace (or supplement) our fossil-fueled economy seems like a worthwhile pursuit. Since nature has been doing renewable energy cycles for quite a bit longer than people have, plants and microbes might inspire some interesting ways to create fuels from sunlight. But even if the research doesn't pan out for practical energy solutions, we'll likely learn something interesting about biological processes. Here are a few quick links on alternative energy projects. As always, StumbleUpon can also recommend some good Techdirt articles, too.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

–The Techdirt Team

    In my opinion, this rush for hydrogen fuels is a lost cause. There is a virtually limitless supply of energy under our feet called geothermal. Unfortunately the coal companies have a virtual stranglehold on energy production and permitting for geothermal plants can take 3-6 years for approval. Places like Iceland generate 100% of their energy this way, and though the US is the largest producer of geothermal energy, the overall percentage generated vs coal or nuclear is quite small.

      You are correct. Just for reference, there are only three sources of "unlimited" energy. They are from the Sun, the Earth and the Moon: Solar, geothermal, and tidal. All other energy, including fossil fuels and nuclear, will eventually run out.

    AS will the sun, but we've a few years left before we need to worry . . .
