In 2015 humans used about 575 quadrillion Btu (British thermal units) of energy, according to the US Energy Information Administration. (575 followed by 15 zeros; a Btu is roughly the energy released in a single match.) With a global population of 7.3 billion, that worked out to 78 million Btu per person that year.

Nearly 40% of all the energy humans use globally goes to making electricity. Coal accounts for 41% of the world’s electricity generation; 17 countries get more than half of their electricity from it, including Mongolia, Poland, China, India and Australia. Natural gas accounts for 22% of global electricity generation; 31 countries get more than half of their electricity from it, including Qatar, Belarus, Tunisia, Singapore, Bangladesh, Nigeria, Mexico and The Netherlands. Nuclear energy accounts for 11% of global electricity generation; four countries get more than half of their electricity from it, France, Slovak Republic, Belgium and Hungary. Hydro power accounts for 16% of global electricity generation; 37 countries get more than half of their electricity from it, including Nepal, Norway, Ethiopia, Georgia, Brazil and Canada. Renewable energy sources like wind, solar and geothermal, account for 5% of global electricity generation. As of 2013, no country got more than half of its electricity from non-hydro renewables, although Denmark was close, at 46%.

In the southern Indian city of Tuticorin, a coal-fired thermal power station captures carbon dioxide and turns it into baking soda. The company claims that as much as 66,000 tons of the carbon dioxide could be captured at the plant each year. The company also says it is the first example of an unsubsidized industrial plant capturing COfor use.

The United Arab Emirates (UAE) has unveiled its long-term energy strategy. The Middle East country will increase the contribution of renewables in its total energy mix to 50% by 2050. Half of the country’s energy will from renewables and nuclear, with the remaining half coming from fossil fuels (natural gas, clean coal)The strategy also wants to change the country’s energy consumption culture by slashing residential energy consumption by 40%. The UAE’s Emirates Nuclear Energy Corporation (Enec) is currently building one fo the world’s largest nuclear power plants. When complete, the power station is expected to deliver up to 25% of the UAE’s electricity.

Lebanon announced renewable energy will make up 12% of the country’s total electricity generation in 2020. Most of the Middle East country’s aging electric power plants run on oil and gas oil. Renewables currently account for about 5%. The country is in the process of increasing the expansion of solar, wind and hydro power.

Canada and the United States are in the process of approving a proposed $1 billion electric transmission line that would carry electricity from the Canadian province of Ontario across Lake Erie to the state of Pennsylvania. The 73-mile line, much of would be buried beneath Lake Erie, would connect a hydroelectric power station in Nanticoke, Ontario, with another in Erie, Pennsylvania. The transmission line would be capable of carrying up to 1 gigawatt – enough to power 810,000 homes in the northern US.

A new hybrid-electric bus in Stockholm, Sweden recharges wirelessly in 6 to 7 minutes. In the pilot project, the bus charges overnight via a standard wired charger. Then, each time it comes to the final stop throughout the day, it quickly recharges. Unlike most cars, buses drive all day long and can’t rely on an overnight charge alone.
