trong lĩnh vực sức khoẻ, nhờ vào những tiến bộ khoa học tuổi thọ của con người sẽ tăng lênIf the world invests enough in clean energy, we will be able to rely almost entirely on renewable energy by 2050 — cutting energy sector greenhouse gas emissions by 80%, according to a World Wildlife Fund (WWF) report. "[I] t is technically feasible to supply everyone on the planet in 20chúng ta sẽ khai thác có hiệu quả hơn các ngành năng lượng như ngăng lượng gió năng lượng mặt trời 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 2r of global GDP, and take into account increases in population and travel.Solar energy, now comprising only. 02% of the worlds energy supply, could provide half of the worlds 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 2r of the worlds electricity, could provide 25% of the worlds 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 Earths 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.
