Renewable energy overtook coal as the world's leading source of electricity in the first half of this year - a historic first, according to new data from the global energy think tank Ember. Electricity demand has grown around the world but the growth in solar and wind was so strong it met 100% of the extra electricity demand.
However, Ember said the headlines mask a mixed global picture. Developing countries, especially China, led the clean energy charge but richer nations including the US and EU relied more than before on planet-warming fossil fuels for electricity generation.
A number charities and non-profit organisations are calling for the government to maintain its intervention in the energy market after April for those on the lowest incomes by offering a social tariff for the poorest in society. Quite how this will operate would be interesting to see, but effectively its intention would be to shield those people on low incomes if energy bills remain high.
From an evaluative perspective, it will have an opportunity cost, it also affects incentives within the market and I'd wonder whether or not it is 'good economics'...
