A summary of the history of global warming and how the public has viewed the problem throughout the years

Despite being touted as the best way to clean up dirty fossil fuels, commercial deployment of carbon capture storage (CCS) in the power industry has been near non-existent. Now, for the first time ever, a coal-fired power plant is being retrofitted with CCS.

Renewable energy now forms one-third of the world's total energy capacity, according to a new report by the International Renewable Energy Agency (IRENA). The agency found that 171GW of renewable energy was added to the global system in 2018, with an annual increase of 7.9%. Two-thirds of new power generation capacity added in 2018 came from renewables.

Against a background of escalating tension between the US and Russia over events in Ukraine, oil companies from each country have been working to overcome the numerous challenges of extracting oil from the Arctic Ocean. Having completed one of the largest Arctic expeditions in history to understand the challenges, the partnership has now started to drill.

With the UK going coal-free for a record-breaking 90 hours over the weekend, energy sources such as solar and onshore wind now play a key role in generating electricity. However, with the urgent need for new energy sources to replace the 60% of the electricity produced worldwide by fossil fuel combustion, it has become necessary to look further afield to alternative energy sources.

For a few years a team of academics in the US has been on a quest to revolutionise the way buildings are cooled. Now, ongoing research by one of them could be about to deliver one of the biggest gamechangers to building management, as Andrew Tunnicliffe finds out.

An exhaustive global study has found that climate change is set to drive up energy demand significantly by 2050, suggesting policymakers and the energy industry need to take action now to prevent a surge in energy related costs over the next few decades.
