Cities Are The Key For Adjusting To Changing Climate

Readers of this site have seen lots of evidence that in the 21st century the best place one can live for a small carbon footprint is in urban areas. Things like increased infrastructure costs and higher costs of living associated with automobile use in rural & suburban places are obvious reasons why denser areas are better.

Now we can add even more reasons to live an urban life thanks to research from the IPCC and WWF.

The latest assessment by the International Panel on Climate Change (IPCC) indicates a global carbon budget, or the estimated amount of carbon available to burn if the world is to limit runaway climate change. We also know that, if action is not taken soon, all the allowable emissions would be locked in by energy infrastructure existing within five years from now. Time is short.

The good news is that we know where to take action to prevent such lock-in and build a resilient energy future. Most of today’s emissions come from cities, and within that, the vast majority from three sources: the energy used to create electricity, to heat and cool buildings, and for transportation. From the Earth Hour City Challenge, a year-long programme launched by World Wide Fund For Nature (WWF) to identify and promote cities that are leading climate action, it is clear that cities, and their mayors worldwide, are already demonstrating innovative solutions to reduce dependence on fossil fuels in each of these sectors.

Iceland Demonstrates Magma Power Plant

Iceland recently demonstrated that it’s not only possible to use the core of our planet to generate power, but it’s feasible. Iceland’s geothermal operations are the envy of the world and they tend to push boundaries in their search for more energy. Due to this recent development geothermal operations in places like Hawaii are looking to build their own power plants.

The borehole is located in Krafla, in northeast Iceland, near a volcanic crater. The hole created a shaft with high-pressure, super-heated steam that could power a nearby electrical plant, the project leaders said.

“According to the measured output, the available power was sufficient to generate up to 36 megawatts electricity, compared to the installed electrical capacity of 60 megawatts in the Krafla power plant,” IDDP stated in a document.

China’s Wind Turbine Industry Booming

For years China has been trying to improve its sustainable energy production but to do so Chinese companies had to rely on patents and techniques from the rest of the world. Due to an increase in demand (and production knowledge) China is now poised to make the best, most efficient, and easiest to maintain wind turbines.

Already, the amount of wind energy outputted in China puts the rest of the planet to shame.

However, since China’s total generation is more than that of all European Union countries combined, wind’s percentage is large in absolute terms.

Liming Qiao, China director of the Global Wind Energy Council (GWEC), said: “Two per cent sounds small but it’s not when you consider China’s total electricity.

“In fact, last year wind surpassed nuclear to become number three after coal and hydro, and it’s got a lot more potential.”

The sheer scale of the wind market is encouraging mass production which has lowered prices and fostered innovation.

Until recently, Chinese wind manufacturers produced Western-designed turbines under licence. Some acquired a reputation for turning out inferior products.

Now, the wind boom has led to a flurry of new designs. Goldwind, for example, offers a turbine which does not need a gearbox but instead has a “direct drive” system designed to be cheaper to maintain.

Beets for Road Ice Removal

The traditional approach to deicing roads is to cover the roads (and thus the ground around the road) in salt – which is absolutely awful for the environment. Because so many people drive cars the demand for road salt is high and has come to negatively impact local economies and environments.

There is a solution to make salting less damaging and it’s already being used in some communities.

Beets are usually just used to create sugar or, like at Schrute Farms, beet soup. In Ontario roadworks departments have been using a byproduct from beet sugar processing to clear ice off of roads. They mix the beet byproduct with salt to create a new brine that works better and harms less.

Niagara Region has used the mixture for about three years, resulting in a 30 per cent reduction in road salt which damages tender fruit trees and vines, said Dave MacLeod, the region’s manager of transportation operations and technology.
The Ontario transportation ministry is working with Oakville and Grey County to test the effectiveness of other beet juice-based products that are added to brine, said a ministry spokesman.
“The ministry’s objective is to provide safe highways for all travellers by using the best available technology. At the same time, we recognize our responsibility to protect the environment, so we use technology to help us determine the best way to clear our highways in the most environmentally friendly, cost-effective way,” he said.
