Wind Turbines May Offer Green Energy In NYC

At a glance, New York City might not seem like a particularly “green” town, given all its traffic and densely built-up neighborhoods.  But on a per-capita basis, it consistently ranks as one of the most eco-friendly cities, thanks in large part to its unparalleled mass transit system and the small size of most homes and apartments.  And the city may …

Can Nuclear Energy Be Green? Thorium And Traveling Wave Reactors Give It A Shot

The recent events in Japan have sparked renewed debate over the risks of nuclear energy. Nuclear energy advocates defend uranium as a sustainable source of energy that is relatively safe, that is until something goes wrong. Opponents have long maintained the health and environmental risks associated with uranium mining and nuclear waste alongside the threat of nuclear power plant accidents …
