In an era of climate change and extreme weather, a microgrid — a self-sufficient, energy-generating distribution and control system — puts communities on the path to self-reliance.
Building renewable energy infrastructure involves mining for materials such as lithium, graphite and cobalt. If not done responsibly, that could cause huge environmental damage.
Halide perovskites are cheap, versatile and remarkably efficient as both solar cells and light emitters.
Methane bubbles form in a pit digester on a dairy farm as bacteria break down cow manure. The methane can be collected and used as an energy source.

A technological arms race in the 80s resulted in a world-first solar cell, that today underpins half the world’s solar power.
New research shows Ontario doesn’t really need nuclear energy, and its absence would not have an impact on emissions in the province’s energy sector.

Nuclear power isn’t needed to meet Ontario’s electricity needs. And the absence of nuclear power won’t have any impact on emissions in Ontario’s energy sector.

Australia is installing renewable energy at more than ten times the global average. This is excellent news, but raises serious questions about integrating this electricity into our grids.
The design of the global money game is the real antagonist in the fight against climate change. But the call to arms tends to be directed at the players who have had best luck with the dice.
Wind energy has played a major role in Australia’s fulfilment of the renewable energy target.
