Energy at any cost?
If all else is uncertain, how can growing demand for energy be guaranteed? A review of Vaclav Smil’s Natural Gas.
Renewable Energy
An Energy Diet for a Healthy Planet – Part II
Now one might think with all these heat losses that going all-electric isn’t a good idea until all our electricity is produced by hydro and renewables. One would be wrong.
How big is that hectare? It depends.
It’s not always simple to calculate how much area is occupied by an energy installation – especially if the effects of the facility are dispersed in space and in time. Can Power Density account for the afterlife of technologies?
Changing Everything
A transition to renewable energy is often given a significance that goes well beyond its immediate impact: it would somehow make our exploitative relationship to Nature more environmentally sound, our relationship to each other more socially equitable.
State of the transition, March: Falling Global Carbon Emissions from Energy
The great global energy transition is accelerating. Who could have imagined a few years ago that global carbon emissions would stall in 2015, spurred by a rise in renewable energy?
Timetables of power
Fossil fuels are polluting and in limited supply, but they give us copious amounts of energy from small areas of land. Doing without these concentrated fuels won’t be a simple matter of trading a gas tank for a plug-in. A look at Vaclav Smil’s Power Density.
Our Economic Growth System is Reaching Limits in a Strange Way
We don’t just extract fossil fuels. Instead, whether we intend to or not, we get a lot of other things as well: rising debt, rising pollution, and a more complex economy.
Renewables Ideas Make World of Difference
Carbon-negative cars, cost-effective organic solar cells and electricity from waste treatment are possible clean energy options as scientists stretch the laws of physics.
A Snapshot of Transition in Ireland: the Fight for Community Energy
For many years energy, climate change or Transition were not on people’s radar in Ireland, but circumstances have been changing and people are now waking up to our energy challenges.
A Case Study of Small Hydropower
Small hydropower (<10 MW) has been gaining ground as a renewable energy source that could play a significant role in both reducing our fossil fuel use in many developed and developing countries and in helping some regions of the world that are currently handicapped by inadequate electricity supplies.
Renewable Energy Growth Blows EIA Forecasts Out of the Water, Again
Another year, another U.S. Energy Information Agency (EIA) assessment report that makes the agencies own forecasters look foolish.
Energy Access for the Developing World
What’s the best way to bring energy to those in the developing world who lack it?
