A use for solar energy I can get behind.

Solar energy-driven process could revolutionize oil sands tailings reclamation

Quote:
Cleaning up oil sands tailings has just gotten a lot greener thanks to a novel technique developed by University of Alberta civil engineering professors that uses solar energy to accelerate tailings pond reclamation efforts by industry.

Instead of using UV lamps as a light source to treat oil sands process affected water (OSPW) retained in tailings ponds, professors Mohamed Gamal El-Din and James Bolton have found that using the sunlight as a renewable energy source treats the wastewater just as efficiently but at a much lower cost.
The irony.

Listen for the progs to scream...

What? Say it ain't so...

Renewables don't work

Quote:
Several recent analyses of the inputs to our energy systems indicate that, against expectations, energy storage cannot solve the problem of intermittency of wind or solar power. Not for reasons of technical performance, cost, or storage capacity, but for something more intractable: there is not enough surplus energy left over after construction of the generators and the storage system to power our present civilization.

One more on fracking.

Landmark Fracking Study Finds No Water Pollution

Quote:
The final report from a landmark federal study on hydraulic fracturing, or fracking, found no evidence that chemicals or brine water from the gas drilling process moved upward to contaminate drinking water at a site in western Pennsylvania.

Destroying peat bogs during the construction of wind turbines has unforeseen consequences.

Wind farms will create more carbon dioxide, say scientists

Quote:
Wind farms are typically built on upland sites, where peat soil is common. In Scotland alone, two thirds of all planned onshore wind development is on peatland. England and Wales also have large numbers of current or proposed peatland wind farms.

But peat is also a massive store of carbon, described as Europe’s equivalent of the tropical rainforest. Peat bogs contain and absorb carbon in the same way as trees and plants — but in much higher quantities.

British peatland stores at least 3.2 billion tons of carbon, making it by far the country’s most important carbon sink and among the most important in the world.

Wind farms, and the miles of new roads and tracks needed to service them, damage or destroy the peat and cause significant loss of carbon to the atmosphere, where it contributes to climate change.
M'bold.

Tsk, tsk...

Well...... if you delve into the comments on that story and the source of the original report, plus a little poking around the intertubes, you'll find a lot of well-reasoned arguments against its conclusions (and importantly, its assumptions). As one commenter has noted, the original study uses data that is now 7 years out of date.

There are ample examples of energy storage systems that can address many of the potential roadblocks raised by the study. The efficiencies of solar production are improving daily, as is the reduction in toxic / exotic / expensive material inputs.

This aggressive pavlovian response to anything 'green' is terribly tired. A shame that people are so rabidly against the possibility of moving away from the fossil fuel economy that they dismiss and ridicule efforts to find creative and sustainable paths away from it.

Not surprised to see this knee jerk support of anything painted any shade of green... the truth is most of the "sustainable" energy sources are ridiculous medieval folk remedies in a world that needs high tech energy solutions that are currently being fulfilled by fossil fuels.

They're not there by alonggggg shot. You get a day older every day, but it doesn't mean you will live forever.

I really don't think wind turbines farms are the way to go. Yes wind turbines for small applications may be ok, but on a large scale I don't think they work. They take too much stress from the wind and cost too much to put up and maintain.

My mom once commented when she watched a reporter reporting from the middle of a wind farm, "are they really any good when half of them are damaged and not working". Sure enough, a quarter of them were broken and not even running.

Solar is great for efficient production of hot water. The loss of energy converting it to electricity is staggering.

Completely agree. And it's dirt-cheap for anyone with a few tools and some ability.

"Staggering"? Hyperbole much? There are lots of ways to do it, some more expensive than others. And solar panel prices are on a constant march downward.

And even if there is a loss of energy in the conversion - well - given that the source is pretty much akin to infinite, is that really a problem?

It's not a problem unless rate payers have to foot the bill.

I'm all for people experimenting--just don't have me pay for the experiments. I suspect some nanotech solution will come along soon enough to throw all of this stuff on its ass.
