anthraciteThe ranks of coal (from most to least carbon content) are as follows: anthracite, bituminous coal, sub-bituminous coal, and lignite. The coal with the highest carbon content is the best and cleanest type of coal to use.
Does coal have a future?
At least 28 countries have now joined the alliance, which requires OECD signatories to end coal by 2030, and developing ones by 2050. Rising carbon prices and the shift towards gas as a low-carbon ‘transition fuel’ are contributing to coal’s decline, but the collapsing cost of renewables is the real game changer.
How long will coal last?
around 150 yearsThere are an estimated 1.1 trillion tonnes of proven coal reserves worldwide. This means that there is enough coal to last us around 150 years at current rates of production. In contrast, proven oil and gas reserves are equivalent to around 50 and 52 years at current production levels.
How beneficial is coal to life?
Coal accounts for over 37% of the world’s electricity supply. It is fundamental in powering homes and industry, providing energy for transport and producing steel and concrete.
