Quick action urgently needed on renewables

Two great articles and discussion over at ZeroCarbonCanada.ca

Bill McKibben's piece (also available in the Toronto Star) urges Canadians to get past the green energy backlash and get to work building renewable energy projects:

In the ideal world, we’d do everything slowly and carefully - but this planet is rapidly becoming the worst of all possible worlds, a place that before my daughter dies may well see temperatures exceeding anything since before the dawn of primate evolution. A planet facing hundreds of millions of environmental refugees as a result of rising seas, with heat waves like the one that killed 35,000 in Europe becoming commonplace occurrences.

The evidence gets worse by the day: already whole nations are evacuating, the Arctic is melting and we have begun to release the massive storehouse of carbon trapped under the polar ice. Scientists figure the “safe” level of carbon dioxide in the atmosphere is about 350 parts per million. This is the most important number in the world. Go beyond it for very long and we will trigger “feedbacks” that will result in runaway warming spiraling out of any human control and resulting in a largely inhospitable planet.

We are already well beyond 350 and accelerating rapidly in the wrong direction.

So when local efforts to delay or stop low-carbon energy projects come into conflict with the imperative to act urgently on global warming, they have to take second place. Because even if we win every other battle, if we lose 350, it won’t make any difference at all. You can “keep” every river and bay and lake and mountain and wilderness, but if the temperature goes up 3 degrees globally, it won’t matter. The fish that live there won’t be able to survive, the trees that anchor the landscape will die, the coral reefs will bleach and crumble. Whatever the particular part of the world that we’re each working on, it’s still a part of the world. Global warming is the whole thing.

Dr. Andrew Weaver's piece is along the same lines:

The public debate has become a caricature. People complain about windmills blocking their view. Kayakers complain about seeing a transmission line on their weekend excursions. The public dialogue is riddled with outlandish and demonstrably false assertions such as windmills will devastate local bird populations or a hydro project will create more greenhouse emissions than it will displace by eliminating a coal-burning power plant. Some of the most insidious arguments attempt to slow things down: that we should do more planning, that we should do energy conservation first and build renewable energy later, that we shouldn’t do anything until China does.

These arguments are fundamentally not serious. They come from groups and spokespeople that have simply not grappled with the math — with the scale and speed at which we must eliminate fossil fuel emissions.

...

We need a global agreement and action. This means rich countries like Canada must take decisive action and demonstrate that we are willing to shoulder the responsibility for what our emissions have done to the rest of the world. To that end:

We need to build and transition to entirely emissions-free energy.

We need to tax carbon emissions and legislate their elimination.

We need aggressive efficiency policies.

These measures must happen extremely quickly and on an unprecedented scale. We desperately need all civil society organizations advocating as hard as possible for this effort and we cannot afford to have so-called environmentalists opposing what science shows to be necessary.

On wild cards and delusions...

Another excellent piece from Tyler Hamilton in The Star:

Canada's oil and gas sector is a crucial engine of our economy and isn't going away, so any technologies that help reduce or capture emissions are both welcome and necessary.

But can these technologies help us right now, particularly to justify rapid expansion of oil-sands projects? And, taken alone, are they enough?

Don't bet on it. Climate expert James Hansen, director of NASA's Goddard Institute for Space Studies, got it right earlier this month when he called the oil sands a climate-change "wild card" that shouldn't be played. "You just can't do it, that's what politicians and international leaders have got to understand."

Canada, however, is playing that card. It's gambling that technology will make sure the house wins.

But here's the rub: Prime Minister Stephen Harper is delusional if he believes that capturing carbon dioxide from coal plants and oil-sands operations and storing it underground is going to have a material impact on reducing greenhouse-gases over the next decade, let alone the next two decades.

Not because the technology doesn't work or isn't safe, which is still up for debate, but because it's too expensive and risky to deploy on the scale that's required.

The thing is, Harper isn't really delusional. He's just greenwashing, which according to Wikipedia occurs when "significantly more money or time has been spent advertising being green."

Compare that to Chantal Hebert's piece in the same edition (Oil sands exposé deserves more energetic response). It's hard to tell from her column if she thinks that Harper should actually do something about the environmental problems of the oil sands, or if they just need better PR!

OPG testing biomass fuel in coal-fired power plants

Finally - a good idea from Ontario Power Generation:


Duncan Hawthorne, chief executive of nuclear operator Bruce Power, wants to build a new nuclear plant beside Nanticoke. It will create jobs and stimulate the economy, he argues. It will provide voltage support for the grid and more than replace the power lost when Nanticoke is mothballed (though we all know he wouldn't be able to build a new nuclear plant before 2014).

When Hawthorne proposed the new plant three weeks ago, Energy and Infrastructure Minister George Smitherman was quick to shoot him down. Smitherman has different plans for Nanticoke, and said in an interview last week he's "cautiously optimistic" it will work.

The idea: burn biomass instead of coal.

"It's an exciting option," says Smitherman, who in September directed the Ontario Power Authority to look at ways to add more renewables to the grid. He specifically asked the power authority to explore the potential of burning biomass in coal-fired plants. "I think it's going to be about 18 months before we have enough information to know what is possible."

Figuring out how to burn biomass such as wood or switchgrass pellets could solve many problems at once. The government could make good on its commitment to phase out coal. It could keep a sizeable amount of electricity generation in the area without having to build new transmission lines or plants, whether nuclear or natural gas.

It could continue to provide some much-needed voltage support for the grid, meaning less need to install expensive gear to compensate for the voltage losses.

It could keep local jobs and potentially create even more. That's because instead of importing coal, which is a flow of capital out of the province, OPG's need for biomass would stimulate a local industry for collecting wood or agricultural waste and turning it into fuel pellets. If an energy crop like switchgrass or poplar is chosen, it would also create opportunities for farmers that have seen markets for tobacco and ginseng disappear.

Most of all, it would lead to much cleaner power. Sulphur dioxide from biomass, particularly wood, only exists in trace amounts. There's no mercury. There are nitrogen oxides emissions, but far less than burning coal and some units at Nanticoke have selective catalytic reduction systems that can remove much of those emissions. Pollution-control equipment at Nanticoke that keeps soot and other particulates from entering the air can also be used for biomass.

That leaves greenhouse gases. When you burn wood or agricultural waste it releases the same amount of carbon dioxide as burning coal. The difference is that the CO2 that enters the air is theoretically carbon-neutral – that is, it gets reabsorbed in new plant growth. I say theoretically because it assumes biomass harvested is plant life that's replaced.


But, I wonder how much biomass you would need to replace all that coal? And where would it come from?

Toronto Star: A ray of sunshine for solar energy

Another good story from Tyler Hamilton (The Toronto Star).

TheStar.com | Business | A ray of sunshine for solar energy:

Morgan Solar has come up with a completely different approach that relies on what it calls a light-guided solar optic. Basically, pieces of acrylic or glass are designed to capture sunlight as it hits a triangular surface less than a centimetre thick. Once inside the material, the sunlight is trapped and corralled through a bottom layer to one corner, where a tiny sliver of solar cell is positioned to absorb the barrage of concentrated light.

The triangles are packaged together to form a square about the size of a Compact Disc case and dozens of these squares make up a single panel.

"It's bloody amazing," says William Masek, president and chief technology officer of Brockville-based Upper Canada Solar Generation Ltd., which has plans to build 50 megawatts of solar farms in Ontario. In the next few weeks he will begin field-testing Morgan Solar's prototypes. "They probably have the most breakthrough solar technology announced in a long time."

Masek says the cost savings for him could be enormous if the technology, as claimed, can affordably convert more of the sun's energy to electricity per square metre than conventional solar panels. "With traditional solar panels we'll need over a thousand acres of property. But if we switch to their system, we can cut that land requirement in half and also substantially cut our costs," he says.

The materials that make up the panels are nothing fancy or expensive, Nicolas Morgan says during an interview at the company's office. The solar panels are flatter than the competition, lighter, cheaper to build and can concentrate the light at up to 1,500. "This is completely new. Nobody has done it this way," he says.

Now comes the tough part – turning it all into a commercial product without falling into the valley of death, that point in the life of a technology start-up where the difficulty of finding funding ends up starving promising companies.

Toronto Star: Clean coal is no quick fix

A good piece on "clean" coal in the Toronto Star today.

TheStar.com Clean coal is no quick fix

Alberta and Saskatchewan are determined to clean up coal and pump carbon dioxide back into the ground, two achievements that would turn the world's dirtiest fossil fuels – coal and tar-sands oil – into a climate-friendly source of energy.

That's the theory.


...

The fossil-fuel folks often like to poke fun at wind, solar and conservation efforts by dismissing them as "playing at the edges." It also appears clear the federal government is putting disproportionate weight on the ability of clean coal and carbon-capture technologies to reduce Canada's greenhouse-gas emissions.

Not everyone in the industry is convinced, including Alex Pourbaix, president of energy at TransCanada Corp., a natural gas pipeline and power generation company headquartered in Calgary.

"The cost of these types of technologies are very, very uncertain," Pourbaix told investors in Toronto last week, explaining that they don't stack up well when compared to natural gas. Natural gas is costlier than coal, but emits half the CO2 and very little sulphur dioxide.


...

Their electrical demand, or what's often called parasitic losses, can range from between 10 per cent and 50 per cent of power being generated. In the United States, that means if all existing coal plants were converted to clean coal and their emissions were captured and sequestered, it would require 320,000 megawatts of new electrical generation to compensate for the parasitic losses – that is, for the extra power required to capture the CO2, compress it, and pipe it safely into permanent underground storage.

Yikes. That's about 10 Ontario electricity systems. Or about 600 more coal plants. Certainly a good way to keep a dinosaur industry from going extinct, isn't it?

The Globe's wishful thinking, and a cartoon that says it all!

The Globe and Mail "endorsed" Harper for PM today (really, they damned him with faint praise). Most of their editorial is comprised of this kind of wishful thinking (emphasis is mine):


We also urge Mr. Harper to revisit his wholly inadequate climate-change plan. Canada and the world need to develop alternatives to fossil fuels. Counterintuitively, Mr. Harper may be the best-positioned Canadian politician to lead on this important issue, should he ever condescend to take it seriously. Given the impregnability of his Alberta base, he could strike a modern Nixon-to-China on climate change.
If you need cheering up after reading the Globe editorial, check out the Star's editorial cartoon.

As we've said before, the world and the climate cannot afford to wait for Harper to have a change of heart. Sure, circumstances may eventually force him to act in a meaningful way (as he is now being forced to do in the banking crisis), however by that time Canada will be far, far behind the rest of the world.

We need action now. We need the kind of leadership Mr. Dion is showing on this file.

Vote on environmental issues, scientists urge

More support for strategic voting!

TheStar.com - Vote on environmental issues, scientists urge:

"More than 120 of Canada's top climate scientists have signed an open letter criticizing Conservative government policy and urging Canadians to vote 'strategically' for the environment in next week's federal election.

'Global warming is the defining issue of our time,' said Andrew Weaver, a lead author with last year's Nobel Peace Prize-winning Intergovernmental Panel on Climate Change."


Here is the link to the original letter, and some quotes (emphasis added):

We have been disturbed by what we perceive to be a lack of attention to the environment during this election campaign. While it’s clear the public accepts that global warming is a threat, it seems people have simply no idea how serious this issue is. Global warming is without a doubt the defining issue of our time, and we cannot let economic turmoil in the USA dissuade us from addressing the problem. Dealing with the environment means dealing with economics in a sustainable way.

Global warming is a problem that must be dealt with now, before it’s too late. Any further delay will only increase the risks of damage and costs of action. The world needs to start down a path of greenhouse gas reduction to avert the most serious consequences of global warming. Many may not realize that even if we immediately stabilized atmospheric greenhouse gases at current levels, the Arctic would still go ice free in the summer, between 10% and 25% of the world’s species would still be committed to extinction, and weather will continue to become more extreme.


Economists around the world agree. There is only one way to deal with global warming. And that is to put a price on emissions. This can be done through either a carbon tax, a cap and trade system, or both.

The carbon tax provides price certainty, is easier to implement, more transparent, easy to make revenue-neutral and less open to abuse. Cap and trade systems require self-regulation and reporting, cumbersome bureaucracy to administer and take a long time to implement while details, such as credit for early action, process of awarding emissions permits, and reporting requirements get worked out.

In both cases the price is passed on to the consumer through an increase in the price of carbon-intensive products. In the carbon tax case the consumer sees what price is added whereas it is obscured in the cap and trade system.
