Transport innovation of the week: solar trains

Solar power is used on the world’s rail networks in a variety of ways. In Britain we have the solar bridge at Blackfriars, and Belgium has a solar tunnel that feeds into the network. Indian railways are pioneering solar power to run train interiors. So far I’m not aware of anyone directly powering the trains […]

The US states taking action on climate change

Climate change action is firmly off the agenda for America’s new Republican administration. Actually that’s not true. It is on the agenda, but only to water down or remove any current commitments. Though they may change their minds at some point, for now it looks like the US government is only going to make things […]

Iran’s renewable energy peace dividend

The idea of a ‘peace dividend’ comes from the Cold War. As the decades of tension eased and the threat of conflict receded, world leaders saw a chance to collectively reduce their military budgets. Armed forces could be demobilized, nuclear weapons destroyed, and expensive programmes drawn to a close. There were potentially huge savings, and […]

Indian Railways is putting solar panels on trains

A couple of weeks ago I wrote about the possibilities of self-charging solar vehicles, and just how many solar panels you can stick on a car. Here’s a related concept for this edition of ‘transport innovation of the week‘. Indian Railways has been exploring a variety of ways of saving energy and reducing emissions, and […]

Building of the week: Princess Elizabeth Antarctica

Heating is the biggest use of energy in a house. That means that generally speaking, the colder the climate, the harder it is going to be to build a zero carbon home. But it should always be possible, and in an age of climate change and rising energy prices, a cold climate is no reason […]

How China is putting the brakes on coal

Last week I wrote about China and the shift in its energy policy. I mentioned that China is over-investing in coal power, and that the number of power stations being built wasn’t necessarily an indicator of coal use to come. This week we saw confirmation of that problem, as the government instructed 11 different regions […]

A map of the countries with the most renewable energy

One of the more popular posts on this blog over the past few years has been the one on countries with 100% renewable energy. It’s a list that surprises people, as there are plenty of unexpected countries on there. Here’s a map that makes the same point. It shows the countries that generate over 80% […]

Let’s talk about China

China’s role in global climate change is a contentious one. For years it’s been seen as carbon enemy number one, the careless coal consumer condemning us all to climate catastrophe. It was mostly China that scuppered the Copenhagen talks in 2009, and it is generally accepted that it will be impossible to stop runaway climate […]

The importance of green gas

If we take a look at where energy is used in the home, the biggest slice of the pie goes to heating. The second is hot water. Renewable sources of electricity may be proliferating, but renewable heat is the next big challenge. Until we can decarbonise heating, we won’t be able to reduce household emissions […]

The divestment movement is advancing

For decades, climate change action has focused on carbon emissions, looking at how we could reduce or mitigate the impact of burning fossil fuels. About four or five years ago, emerging out of a post-Copenhagen silence, campaigners began talking about the other end of the supply chain. Rather than reducing emissions, let’s cut to the […]
