Impossible Conundrum: Nuclear Waste Storage
There are a multitude of reasons why nuclear fission reactors make no sense as a part of our energy future (without even thinking about it too much, you've got dwindling supplies of uranium ore; the impossibility of building enough reactors fast enough to cope with climate change challenges; the difficulty finding suitable sources of cooling water for new reactors; the demonstrated problems during heat waves, such as in 2003 when France was forced to shut down reactors when cooling water temperatures became too high; the element of human error that frequently complicates safety issues, as demonstrated mightily during the ongoing Fukushima Daiichi nuclear disaster; and on and on).
Significantly, however, nuclear proponents have consistently dodged the issue that presents a glaring indictment of the entire technology: devising a long-term solution for the end of the fuel cycle, finding a way to contain and store the byproducts of 70 years of nuclear fission, much of it still residing in spent fuel pools—a storage solution that has always been deemed temporary, but with the lack of industry initiatives to move cooler fuel to dry casks and the absence of any progress toward a permanent repository, some 72,000 tons of nuclear waste exist with no plan for long-term storage.
Writing for Truth-Out.org, Gregg Levine analyzes the situation, tracing the initial enthusiasm of the nuclear industry to the present-day confusion.
As he points out in the article:
In retrospect, it's completely insane that we've proceeded with nuclear power generation and proponents continue to present the technology as the solution to global warming when the most fundamental concerns—long-term isolation of the radioactive byproducts—have never been suitably addressed.The crisis at Japan's Fukushima Daiichi facility was so dangerous, and remains dangerous to this day, in part because of the large amounts of spent fuel stored in pools next to the reactors but outside of containment - a design identical to 35 US nuclear reactors. A number of these GE Mark 1 Boiling Water Reactors - such as Oyster Creek and Vermont Yankee - have more spent fuel packed into their individual pools than all the waste in Fukushima Daiichi Units 1, 2, 3, and 4 combined.

Benefitting Energy Consumers with RPS
Amidst the schemes and proposals and attempts to resurrect dead technologies (witness the nuclear power boosters practicing their arcane arts), some progress may be near at hand in the form of the renewable energy portfolio (RPS). A standard requiring that utilities produce 20 percent of their energy from renewable sources is in the works, as reported by blogger David Roberts.
A brief excerpt from a reference extract he highlights:
Solutions are out there if we recognize them and take action.

So for those of you who don't want to read the long post that follows, here are some key takeaway points:
Right now there is a patchwork of over 20 state RPSs. Each has slightly different and sometimes incompatible standards and rules, which prevent interstate trading of energy credits. This inhibits the development of renewable energy and presents a "free rider" problem, with power producers in non-RPS states benefiting unjustly. A national RPS is far preferable to today's patchwork of state RPSs.
Electricity consumers in every region of the country would save money under a national RPS -- up to $49 billion nationwide.
A national RPS would create 80% more jobs than comparable investment in fossil fuels -- the greatest number of jobs in the states that have been hardest hit by the loss of manufacturing.
All states have renewable resources that can be developed.
A national RPS would save billions of gallons of water, reduce air pollution, reduce total land occupied by power generation, and lower CO2 emissions.
Solutions are out there if we recognize them and take action.

A Grassroots Approach
When dealing with a monumental issue, such as global warming, people have a tendency to throw up their hands and say, "Let the government deal with it!" In our current situation, however, where the U.S. government leadership is more interested in maintaining the status quo and finding inventive ways to pretend that global warming is a delusional myth, lasting change originates from the grassroots. The top-down approach isn't working. All the more reason to embrace the bottom-up approach.
This article from the Santa Rosa Press Democrat, People look for ways to cut their carbon footprint, highlights the ways in which people concerned with the global warming problem confront it in highly personal ways.

This article from the Santa Rosa Press Democrat, People look for ways to cut their carbon footprint, highlights the ways in which people concerned with the global warming problem confront it in highly personal ways.
A brief excerpt from this excellent article by Meg McConahey:
"We're not activists. Just two Santa Rosa parents raising two kids. We didn't ever march in anything," said Lisa Ormond, 44, who also was inspired to go on a low-carbon diet after winning tickets to "An Inconvenient Truth" from a local radio station.
Small steps add up
She began bicycling at least two days a week from her subdivision in Bennett Valley to her marketing job at Santa Rosa Junior College. She car pools with girlfriends to soccer games. Husband Randal, an electrical engineer at Alcatel-Lucent, now incorporates most family errands into his commute home from Petaluma rather than making separate trips. She and her son biked together to an after-school class - all dramatic lifestyle changes made in a single year.
"It started a whole avalanche of alternative thinking about some of these issues," Ormond said, from weighing the economic feasibility of getting solar panels to swapping their Honda for an electric car. "These are little ways I know I'm not putting carbon in the air."
In March, the Yale Center for Environmental Law and Policy called the shift in public opinion a "sea change." It found 83 percent of Americans now believe global warming is a serious problem, and 75 percent of them believe their own behavior can have an impact on climate change. And about 81 percent said it's their responsibility to alter their energy-wasting behavior.
