TAILIEUCHUNG - Energy Options for the Future phần 4

Tùy chọn năng lượng cho tương lai 55% gió, biopower 25%, 10% năng lượng địa nhiệt, PV 5%, và nhiệt năng lượng mặt trời 5%. Kết quả là sự bổ sung của 150 GWe nonhydro năng lượng tái tạo 2020-15% tổng công suất vào năm 2020. Trong năm 2012, năm chi phí cao nhất, mức tăng hàng năm là khoảng $ 1B cho đất nước | Energy Options for the Future wind 55 biopower 25 geothermal 10 PV 5 and solar thermal 5 . The result was the addition of 150 GWe of nonhydro renewables by 2020 15 of total capacity in 2020. In 2012 the highest cost year the annual increase was about 1B for the nation including a residential share of about 25 cents per month per household. In 2020 the annual cost savings are about or 37 cents per month per household. An EIA analysis modeled 10 and 20 renewable portfolios in 2020. Their results were that electricity process were higher in 2020. Their renewables mix was biopower 58 wind 31 and geothermal 10 . Natural gas prices decreased by 9 and the total energy expenditures go down slightly. Summary Renewable energy development is at a crossroads. The momentum for renewables has never been greater despite the fact that energy prices are low and there are few immediate energy concerns. IEA 1999 The Evolving Renewable World. National Renewable Energy Laboratory . . DOE Office of Energy Efficiency and Renewable Energy . Climate Change Technology Program . International Energy Agency . NUCLEAR ENERGY KATHRYN MCCARTHY INEEL Role of and Need for Nuclear Energy It is estimated in the EIA s 2003 Annual Energy Outlook that . energy consumption will grow by about per year to 2025. Much of the projected growth is in natural gas and coal and imports will increase from 27 of energy to 35 . In the transportation area imports could rise from 66 to 79 . In this situation nuclear energy could be an important contributor provided nuclear wastes can be handled satisfactorily. In addition if hydrogen becomes an important transportation fuel production of hydrogen from nuclear plants could play a useful role. It is important to note that nuclear energy is 8 of today s energy production in the . and it 93 provides 19 of the electricity. Emission-free generating sources supply almost 30 of
