Oslo runs out of garbage, imports it from rest of the world


Oslo, the capital of Norway, has a strange garbage problem. Too much? No, not enough. At first it might seem like any garbage is too much garbage, but Oslo (like many other cities in Scandinavia and Northern Europe) has built cogeneration plants that produce heat and electricity from garbage -- enough to heat about half of the city. But the locals don't produce enough garbage, partly because of their high recycling rate, so they have to import millions of tonnes of it from places like England and Sweden. They're even considering importing American garbage. (more…)

Researchers discover new way to harvest electricity from plants

electricityplantsIn many ways, plants are the ultimate solar energy technology. Through photosynthesis, plants operate at nearly 100 percent quantum efficiency, meaning that for almost every photon of sunlight that's absorbed, they produce an equal number of electrons, so it's no surprise that for years scientists have been trying to either mimic that process through creating artificial leaves or have found ways to tap plants themselves as energy sources.

Grid Could Run on 99.9% Renewable Energy By 2030

When a British energy minister argued that wind turbines generate a "mere trickle of non-storable energy", some eyebrows were raised. Sure, there are challenges to shifting to clean energy, but with renewables providing an ever larger slice of the energy pie and with a number of studies showing 100% renewable energy is possible with today's technologies, his arguments were at best outdated, and at worst a severe case of misrepresentation and denial.

80% Renewable Energy by 2050 is Possible, Just Using Today’s Commercially-Available Technology

While more research into improving renewable energy technology is certainly a good thing, a new report from the National Renewable Energy Laboratory shows that even if we just had today’s cleantech for the next 40 years, we’d still be able … Continue reading
