Everyone has been getting very excited today with the news that GB has gone a whole week without using coal to generate electricity...the first time this has happened since we first started using coal in the late 19th century, and just 2 years since [...]
In the final post in my energy myths series, I will look at one of the biggest, and arguably most dangerous myths of all - the notion that electricity generated from renewable sources is cheap. Myth #4: Renewable energy is cheap Electricity generated from [...]

Earlier this week, the Government published the results of the second round of CfD auctions, which saw offshore wind secure contracts at lower than expected levels. CfDs were introduced as part of the Energy Market Reform, largely to replace the Renewables Obligation regime which [...]
On Thursday Donald Trump caused outrage by withdrawing the United States from the Paris climate agreement, something widely derided by politicians and the media globally as a retrograde step that literally risks the future health of our planet. Quieter voices, however, suggest that the [...]
