It is much easier to stress the unreliability of RE if you ignore the fact that wind and sun were never meant for baseload energy production, and that hydro, biomass, geothermal, etc. are continuous, storable and in fact easier to turn up/off than nuclear.
The environmental cost of raising cattle through conventional farming, slaughtering the animal and distributing the meat. Producing a kilo of beef causes the equivalent of 36.4 kilos of CO2.
So what unknown but magical benefit to nuclear power exists to make nuclear so incredibly attractive to some political leaders? Unfortunately and admittedly, this author does not know.
SUV drivers pollute the planet with their gas-guzzling snobbism. Or do they?
It would take nothing short of a sea change to overcome Congressional inertia and recover the ground lost in the last 25 years or so. But though the prospects for a truly coherent national energy policy are improving -- and the need has never been greater -- both the citizenry and the current Congress are far too complacent to entertain changes that might involve belt-tightening and discipline.
Replace oil? How can something so monumental be accomplished? Preempt waste, start small, provide better service at lower cost and think better.
Should we choose to have 20% of our power production ideologically clean, or 80% of our electricity needs atmospherically clean? The answer is: we should do both.
Reducing one's energy overhead costs relatively little and produces a revenue stream that appreciates over time. Replacing one's energy infrastructure with on-site renewable systems, in contrast, will require a sizable up-front financial commitment relative to what it will produce over time.
We can change the lifeblood of our economy from oil to ingenuity. It is that way in communications. It was that way with transportation. Open rights of way to innovation. Ingenuity will flourish or fail based on the value created minus the cost to compete.
EIA's monthly and annual predictions have only one purpose: to prevent the mainstream media from alerting the driving public to the fragility of the domestic energy picture.
Oil finding rates -- increasingly difficult and costly-- are now only about 50% of current oil consumption. Does more need to be said for the inevitable "Hydrogen Economy"?
I am no longer worried. Now that I understand there is no energy crisis, no ingenuity crisis, only the need for well-meaning bureaucracies to adapt policies to rapidly changing assumptions, I am terrified.
While all investments pose some degree of risk, the return on a solar energy system is about as safe and predictable as, well, the rising sun. Fortunately for the Earth and its varied inhabitants, the center of our solar system is situated well beyond the reach of humanity's capacity to tamper with a good thing.
I would like to point towards one combination of existing technology that I am convinced could actually do the job of lowering atmospheric carbon concentrations and thus reverse climate change
Using natural gas to produce oil from tar sands is akin to turning gold into lead.
