We laughed when the first survivalists went off the grid in the early 20th century. Paranoid and anti-social, they braced for a doomsday scenario that never quite arrived.
Future Energy
Whatever Happened to Renewable Energy?
An international debate over the relative pros and cons of bioenergy has intensified between environmental organizations, governments and climate change leaders in recent years. This lively discussion has been dragging out by the delayed release of the European Union’s sustainability requirements for solid biofuels (originally expected in early 2012).
Tornado Power
Warm air meets cold, spurring a rush of rotating air, which gathers speed, churning and whistling one hundred metres into the air. The vortex becomes self-sustaining, feeding itself energy as it whips itself into a deadly frenzy. Now a full tornado, it has sublime destructive ability.
Rethinking Reliability
Powering the world entirely through renewable energies is going to bring about some logistical challenges, as technological change always does.
No Slow Death for Nuclear Power
This is a response to “Mourning the Slow Death of Nuclear Power“ in Stu Campana’s Renewable Energy blog.
Energy Independence Through Micro Hydropower
The Greeks invented the watermill sometime around the 3rd century BC and until very recently the basic design of a wheel and cogs has been used throughout the world to harness modest water flows and power machinery. Modern technology has moved on a little bit since ancient Greece, but we’re […]
Battling Canada’s Carbon Addiction
To celebrate the new year, many people have made resolutions – which ultimately may or may not be successful. The nations of the world made their own resolution shortly before the holidays, and what we can expect isn’t entirely clear. What is clear is that climate change is accelerating, and […]
Lessons from Germany
The floor of the North Sea is about to be disturbed by a 2 billion Euro high-voltage undersea cable, stretching from Germany to Norway. Like old friends splitting a bar tab, the two countries are sharing the cost of the cable which will carry electricity from renewable energy back and […]
Concentrated Solar Power: Focusing our Energy
Medicine Hat, Alberta, is branching out. The city has approved a proposal to install the country’s first concentrated solar power (CSP) project. CSP typically employs an array of mirrors to reflect sunlight onto a single point, often at the top of a central tower. The concentrated light quickly becomes heat, […]
