Solar thermal advocates are fond of reminding us that homes, especially those in Canada use about 70 per cent of their energy for heating. As solar photovoltaic prices continue to plummet, some net-zero home builders have started pairing solar PV with air-source heat pumps for space heating and electric resistance water heaters to produce hot water.
If people change their lights and use more energy-efficient appliances, who cares if they believe in climate change? The focus should be on demonstrating how they are freeing up money for other spending, protecting their jobs by making their workplace more competitive and slowing the expensive expansion of the power system.
Chelmick's getaway required the hard work of clearing brush and laying a foundation. The original cabin was 600 square feet and solar-powered, complete with battery storage. Why solar? Chelmick recalls seeing brown streaks across the sky near Lake Wabamun.
I think I'm reasonably well versed in issues surrounding the Energy East Pipeline, both economic and environmental. But I am struck by how, in any official TransCanada communications about environmental implications of the project, climate change is never mentioned.
In Australia, I met young people working on "my" forest who enthusiastically told me about the number and variety of birds they'd seen that day, described plant species and talked about how many trees they had planted. Many were street kids, inspired by the chance to learn about nature and conservation and proud to be re-greening the area. I was impressed by their passion and eagerness. They believed in what they were doing and it provided a small income to get them off the streets.
Raising the minimum wage, diversifying Alberta's economy and supporting working people have my full support, but I'm sorry Premier Notley, I just can't get behind you on pipelines. New pipelines aren't good for the environment, they aren't good for the climate, and I'm sorry, but they aren't good for working people or good governance, either.
A carbon neutral home and net-zero home are similar in that both produce as much energy as they consume over the course of a year. The difference is a net-zero home produces its own energy right on the home, whereas a carbon neutral home can produce its energy elsewhere in the community.
An earthship is an off-grid home that produces its own energy, captures its own water, treats its own wastewater, grows its own food and passively collects the sun's energy for heat. That's the idea, anyways. But ever since the Kinney Earthship was built in the summer of 2014, Duncan Kinney has received many emails about one particular subject: how does it hold up so far north?
The myths we are concerned about, the ones of dubious value, are crazy stories that are passed off as facts when talking about solar energy. To get to the bottom of these solar myths we talked to Gordon Howell, a solar expert with Howell-Mayhew Engineering.
All around the world people took to the streets to help give the earth a voice. From Mumbai to Australia, London to Berlin, Ottawa to Vancouver millions danced, sang, and marched to push our world's elected leaders, currently in Paris for COP21, to increase their ambition, listen to the science and the voices of those most impacted, and lead the world out of climate chaos.
