It has been awhile since we talked about hydrogen cars. In fact, auto manufacturers the world over seem to have pushed hydrogen vehicles to the side of their plate (next to the spinach and garbanzo beans). There are of course exceptions, such as Mazda and Mercedes, but electric cars are all the rage right now, and hydrogen arguably has more infrastructure issues to overcome. The biggest issue; where does one get hydrogen?
A Connecticut company called SunHydro wants to deploy 11 solar-powered hydrogen fueling stations (SunHydro, get it?) along the East Coast, creating the area’s first hydrogen highway.
The idea of using electric cars to store energy for the power grid is a good one, I think. Unfortunately, it may be too expensive at this time to make any sense, according to one recent cost analyst. The same high cost problems that have hindered electric cars in the past mean it may not make sense for the future even beyond 2020, unless the costs come down.
Then again, advancements in battery technology seem to be happening on a daily basis, so maybe it doesn’t make sense today, but tomorrow could be a different story.
Sigourney Weaver narrates “Acid Test“, an illuminating and terrifying NRDC documentary that explains how quickly our planet’s oceans are acidifying due to all of the carbon dioxide that we are pumping into our air. This pollution is causing rapid changes in our oceans’ chemistry that will completely disrupt all life on the planet as we know it on a scale that has not been seen for tens of millions of years.
Whatever the relative merits and drawbacks of biomass are, they are preferable to continuing to mine and burn coal. Until we start to bring large-scale base loading renewable capacity online, we continue inexorably on the same business as usual curve.
Meeting energy needs while being efficient and using environmentally responsible technologies is probably the single greatest change that needs to happen to alter the effects of climate change now. In the United States and the European Union, governments are backing smart grid and renewable energy programs. Undoubtedly, the two technologies go hand-in-hand, but where should we put our efforts (and dollars/euros) first?
The Xingu River — home to some 600 species of fish — is one of the largest tributaries running through the Amazon. But not if the Brazilian state power company has their way.
What would be the world’s third largest dam, called the Belo Monte, would flood over 200 square miles of tropical rainforest; about the size of Tucson, AZ. It would also flood the homes of 19,000 people.
In an attempt to cut their dependency on fossil fuel driven energies, the British government hopes that renewable energy will provide 20% of electricity by 2020. And thanks to a new report, the UK might be looking to Scotland to double their hydropower generation by 50%.
The study by the Forum for Renewable Energy Development in Scotland showed that there were still 657 megawatts of fiscally safe, small scale hydroelectricity schemes available to them. This figure equates to about half the amount of installed hydro generation currently running in Scotland, and could power about 600,000 homes, a quarter of the nation’s homes.
Through a combination of federal grants and private donations, a coalition of seven conservation groups called the Penobscot River Restoration Trust have gathered enough money to purchase and demolish two dams and install a fish bypass on another. By doing so, they hope to replenish the thinning Atlantic salmon, river herring, and many other migratory fish populations.
While the move is unprecedented, it is not without some flaws.
Okay. Let me get this one out of the way: gas hasn’t been all bad. In fact, gas has allowed us to accomplish some pretty amazing things. To be clear, when I say “gas,” I’m using the term as an easy way to loosely refer to all liquid fuel products made from buried and fossilized hydrocarbon deposits.
Ooooh… I can hear the flamers’ keys clicking away furiously already. But, before you type that horribly thought out gunslinging response, hear me out.
Chile wants to make progress, but… does that progress always have to be against nature? Chile’s government is planning a project that could put 4,6 million hectares of the environment in danger.
They are planning to build five hydroelectric dams and a high tension line that will be the largest in the world. It will cross Chile from south to north and thus divide it in two.
