Should we be worried about the US withdrawal from the Paris climate agreement?

...energy needs from renewable sources by 2020 and is even considered a “renewable energy paradise”. Renewable energy initiatives in most other countries are pale by comparison. The US has very different reasons to withdraw from the Paris climate deal. Trump wants a deal “on terms that are fair to the United States” and his reason for withdrawing from the deal is...

The ice-covered ocean worlds of the outer Solar System

...energy from sunlight. The basis of the food-chain in these ecosystems is bacteria that use chemical energy from the hydrothermal vents to convert carbon dioxide into sugars and other biologically useful molecules, a role normally fulfilled by photosynthesis in plants on the Earth’s surface. Studies using data from the Cassini mission have shown that some of the...

Why is Enceladus a possible home for life - and should we visit to find out?

...energy in the water to feed microbial life, scientists have been searching for proof that the right sort of reactions really do occur. [The Conversation] And during its last dive through the icy plumes that Enceladus erupts into space in October 2015, the Cassini spacecraft has finally managed to find it – in the form of molecular hydrogen. The finding, published in...

Offshore wind powers ahead in Europe

...energy policy, and an important element in the battle against climate change. Fossil fuel prices WindEurope, an offshore wind industry group, says that at the present rate of installations it’s likely Europe will be producing about seven per cent of its electricity from offshore wind by 2030. By some calculations, all this building work would seem to make little...

How can we say Bitcoin is overvalued when we don't know how to value it?

...energy consumed by Bitcoin miners (the computers that validate transactions and are rewarded with Bitcoins). Diverging from fundamentals If we take a close look, we can see how the price of Bitcoin may be diverging from these fundamentals. For instance, it is becoming less profitable to be a miner, especially as the energy required increases. At some stage the cost may...

Economic incentives for countries to decarbonise

...energy are already (or will soon be) as low as the cheapest fossil fuels. Climate policy. The Paris Agreement, which aims to limit global temperature increase to well below 2 °C, has now been signed by 194 states plus the European Union, while more than 130 countries have now set or are considering a target of net-zero emissions by 2050. These pledges will drive further...
