2016-01-20: why are the countries of Persian Gulf region announcing ambitios plan for renewable energy when the fossil fuels they produce is so cheap?
The risky business of climate change poses challenges for investors around the globe.
Umbra sheds a little light on solar chargers.
People are complaining of a range of health related problems and are attributing them to wind turbines. The question is: what is the cause of these health problems?
Can we transition to these renewable energy sources and continue using energy the way we do today?
The Vortex, a radical new way to generate wind energy, is a bladeless wind turbine that looks like a giant rolled joint shooting into the sky.
ON THE desk of Chris Case, chief technology officer of Oxford Photovoltaics, there sits a small but heavy vial filled with a canary-yellow liquid. "That's enough for a kilowatt," he says.
It's generally assumed that it only takes a few years before solar panels have generated as much energy as it took to make them, resulting in very low greenhouse gas emissions compared to conventional grid electricity. However, a more critical analysis shows that the cumulative energy and CO2 balance of the industry is negative, meaning that solar PV has actually increased energy use and greenhouse gas emissions instead of lowering them. The problem is that we use and produce solar panels in the wrong places. By carefully selecting the location of both manufacturing and installation, the potential of solar power could be huge. Picture: Jonathan Potts. There's nothing but good news about solar energy these days. The average global price...
If we're going to limit global warming to less than 2C, Australia will need to keep more than 90% of its coal reserves in the ground.
Elon Musk will likely launch a home energy storage pack this Thursday. With it, the solar plus storage energy revolution is sure to pick up speed.
Future historians may look back on 2015 as the year that the renewable energy ascendancy began.
Energy, like roads or hospitals, is merely a means to an end.
The design of a new type of bladeless wind turbine is claimed to be both bird- and bat-friendly, while also being inexpensive and efficient.
Niche applications will help advanced power-grid-battery technology.
This is a once-in-a-generation opportunity for climate activists to attack Big Oil while it's weak and shift us toward cleaner energy.
Carbon Tracker Initiative's Anthony Hobley argues that far from being a disaster for clean tech, low oil prices could aid decarbonisation efforts
