Background & Aims. Patients with recurrent bleeding from gastrointestinal vascular malformations are a challenge to treat. We investigated the long-term efficacy and safety of thalidomide for refractory bleeding from gastrointestinal vascular malformations in an open-label, randomized study.
China is Worldâs Largest Energy Consumer. World consumption of energy has increased 5.6 percent in 2010, according to BPâs Statistical Review of World Energy. This is the largest increase since 1973, which happened to be a memorable year in energy history.
In 2014, world energy consumption for electricity generation was coal 40.8%, natural gas 21.6%, nuclear 10.6%, hydro 16.4%, 'others' (solar, wind, geothermal, biomass, etc.) 6.3% and oil 4.3%. Coal and natural gas were the most popular energy fuels for generating electricity. The world's electricity consumption was 18,608 TWh in 2012. This figure is about 18% smaller than the generated electricity, due to grid losses, storage losses, and self-consumption from power plants (gross generation).
