in the field of health, thanks to scientific advances in the human lifespan will increaseIf the world invests enough in clean energy, we will be able to rely almost entirely on renewable energy by 2050 the greenhouse gas emissions — energy sector cutting by 80 percent, according to a World Wildlife Fund (WWF) report. "[I] t is technically feasible to supply everyone on the planet in 20We are going to harness more effectively the energy sector as the reading pane energy-wind power and solar energy The achievement of that goal "does not demand radical changes to the way we live," according to the WWF report. The changes involve technologies already available, won't cost more than 2% of global GDP, and take into account increases in population and travel.Solar energy, now comprising only. 02% of the world's energy supply, could provide half of the world's electricity, half of building heating, and 15% of industrial heat and fuel in 2050, according to the report, which relies on findings from Ecofys.Wind energy, which currently supplies only 2% of the world's electricity, could provide 25% of the world's electricity by 2050. Although that requires an additional million onshore and 100.000 offshore wind turbines, they will have low environmental impact with proper planning, such as development of turbines that float on water.Other crucial sources of renewable energy will include ocean power that harnesses energy from waves and tides; biomass, which includes plant materials and animal waste; geothermal energy derived from the Earth's crust; and hydropower.Investment in all of these technologies is crucial. Combining power from all of these sources will be important in creating our clean energy future.
