Obama’s Clean Power Plan survives a legal challenge

Yesterday afternoon, the U.S. Court of Appeals for the D.C. Circuit denied motions to stay the EPA’s Clean Power Plan. Wondering what that means, exactly? Here’s a handy legal cheat sheet. What’s the Clean Power Plan? The Clean Power Plan is a set of restrictions on carbon dioxide emissions from the nation’s power plants. Projected to cut the electric sector’s CO2 output to 32 percent below 2005 levels by 2030, the plan is generally acknowledged as one of the most significant efforts to curb greenhouse gas pollution in U.S. history. Unsurprisingly, it’s also quite controversial. Who’s fighting it? Twenty-seven states, along with a bunch of coal companies and coal-dependent utilities, are suing to block the plan, arguing that it exceeds the EPA’s authority under…

My city banned plastic bags — now where am I supposed to recycle them?

Why Anaerobic Digestion Is Environmentally Friendly

The constant battle to reduce greenhouse gases has resulted in a constant search for more environmentally focused waste disposal systems – from an influx of recycled materials being crafted into other useful objects, through to sourcing eco-friendly treatment systems for our waste water – finding new ways to protect the environment is high on everybody’s radar. The Effect Of Anaerobic Digestion It is this constantly reaching for better solutions that has driven Anaerobic digestion to where it is now. By combining biodegradable materials, we now have an additional process for creating electricity and organic compost. This means fewer fossil fuels will be burned to heat our homes, chemical fertilisers won’t be in such high demand and our food will have a milder treatment system in place.

Electric cars: Batteries with brains

The battery is the heart of the electric car. Researchers have developed an energy storage device which is significantly more cost-effective over the entire life cycle in comparison with previous models. If one of the more than one hundred battery cells is defective, it can be replaced easily. Until now, the entire battery had to be replaced.
