Why Nuclear Power Must Be Part of the Energy Solution - Yale E
Growth in the world's population and economy, coupled with rapid urbanisation, will result in a substantial increase in energy demand over the coming years. The United Nations UN estimates that the world's population will grow from 7. The challenge of meeting rapidly growing energy demand, whilst reducing harmful emissions of greenhouse gases, is nuclear power plant essay. In global energy-related carbon dioxide CO 2 emissions rose to Electricity demand growth has outpaced growth in final energy demand for many years.
Increased electrification of end-uses — such as transport, space cooling, large appliances, ICT, and others — are key contributors to rising electricity demand.
The number of people without access to electricity has fallen substantially, and is now below one billion. Aside from the challenges of meeting increasing demand and reducing greenhouse gas emissions, cleaner nuclear power plant essay is a vital need. According to the World Health Organization WHOair pollution is the world's largest environmental risk.
WHO estimates that about seven million people die prematurely as a result of air pollution. Much of the fine particulate matter in polluted areas arises from industrial sources such as power generation or from nuclear power plant essay air pollution which could be averted by electricity use.
Studies have repeatedly shown that nuclear energy is a low-emitting source of electricity production in general. It is also specifically low-carbon; emitting among the lowest amount of carbon dioxide equivalent per unit of energy produced when considering total life-cycle emissions, nuclear power plant essay. Almost all reports on future energy supply from major organisations suggest an expanded role for nuclear power is required, nuclear power plant essay, alongside growth in other forms of low-carbon power generation, to create a sustainable future energy system.
There are many outlooks for primary energy and electricity published each year, many of which are summarised below. Among the most widely-referenced organisations in this regard is the IEA. Each year, the IEA releases its World Energy Outlook WEOnuclear power plant essay, setting out the current situation and presenting a number of forward-looking scenarios. The report's 'Current Policies Scenario' considers only policies firmly enacted at the time of writing, whilst the 'New Policies Scenario' — the central scenario, renamed 'Stated Policies Scenario' in WEO — incorporates policies firmly enacted as well as an assessment of the results likely to stem from announced policy intentions.
In each recent WEO report, a third scenario is included that starts with a vision of how and over what timeframe the energy sector needs to change — primarily to decarbonise — and works back to the present. In each WEO released overthe main decarbonisation scenario had been the ' Scenario'; a scenario consistent with limiting the rise in average global temperatures to 2°C. In WEO, the Scenario was replaced by a new, 'Sustainable Development Scenario'.
This presents a pathway that would address three principal objectives for building a sustainable, modern energy system: access to affordable, clean and reliable energy; reduction of air pollution; and effective action to combat climate change.
For more information on sustainability, see information page on Nuclear Energy and Sustainable Development. Electricity Informationreleased annually from the same source, gives the latest available data on world electricity generation and its fuels. Without anticipated decreases in energy intensity of GDP, global energy needs would double by There are many changes ahead in the sources of primary energy used.
As the use of electricity grows significantly, the primary energy sources used to generate it are changing. In both scenarios generation from all low-carbon sources of electricity is required to grow substantially.
It is especially suitable for meeting large-scale, continuous electricity demand where reliability and predictability are vital — hence ideally matched to increasing urbanisation worldwide.
A major two-year study by the Massachusetts Institute of Technology Energy Initiative MITEI published in September underlined the pressing need to increase nuclear power generation worldwide. It outlined measures to achieve this, including moves to reduce the cost of building new nuclear capacity and creating a level playing field that would allow all low-carbon generation technologies to compete on their merits.
Without that contribution, nuclear power plant essay, the cost of achieving deep decarbonisation targets increases significantly," the study finds. The MIT study is designed to serve as a balanced, fact-based, nuclear power plant essay, and analysis-driven guide for stakeholders involved in nuclear nuclear power plant essay, notably governments. With high carbon constraints, the system cost nuclear power plant essay electricity without nuclear power is twice nuclear power plant essay high in the USA and four times as high in China according to the MIT study.
Annual editions of WEO from the OECD IEA make clear the increasing importance of electricity, with all scenarios expecting demand growth to outpace that of total final energy demand. Also clear across successive reports is the growing role that nuclear power will play in meeting global energy needs, while achieving security of supply and minimising carbon dioxide and air pollutant emissions. It outlines a strategy to limit global warming to 2°C, but is very much focused on renewables.
The report recommended a series of measures including increasing energy efficiency, reducing the use of inefficient nuclear power plant essay power plants, increasing investment in renewables, reducing methane emissions, and phasing out fossil fuels subsidies.
Half of the additional emissions reductions in its Scenario come from decarbonisation efforts in power supply, driven by high carbon price incentives. The IEA acknowledges that nuclear power is the second-biggest source of low-carbon electricity worldwide after hydropower and that the use of nuclear energy has avoided the release of 56 billion tonnes of CO 2 sinceequivalent to almost two years of global emissions at current rates.
Most of the new nuclear plants are expected to be built in countries with price-regulated markets or where government-owned entities build, own, and operate the plants, nuclear power plant essay, or where governments act to facilitate private investment.
WEO had a special focus on nuclear power, and extended the scope of scenarios to The Scenario gives a cost-effective transition to limiting global warming assuming an effective international agreement inand this brings about a more than doubling of nuclear capacity to GWe inwhile energy-related CO 2 emissions peak before and then decline.
In this nuclear power plant essay, almost all new generating capacity built after needs to be low-carbon. For countries that import energy, it can reduce their dependence on foreign supplies and limit their exposure to fuel price movements in international markets. Carbon dioxide emissions from coal use level off after in the New Policies Scenario, though CCS is expected to be negligible before CO 2 emissions from gas grow strongly to Ten countries account for almost three-quarters of the world total for fossil-fuel subsidies, five of them in Middle East notably Iran and Saudi Arabia or North Africa where much electricity is generated from oil, and where nuclear power plants and renewables would be competitive, but nuclear power plant essay those subsidies.
Globally, nuclear power capacity is projected to rise in the New Policies Scenario from GW in to GW inaround 20 GW lower than projected last year. WEO also included a "Low Nuclear Case which examines the implications for global energy balances of a much smaller role for nuclear power. Its effect would be to "increase nuclear power plant essay bills, heighten energy security concerns and make it harder and more expensive to combat climate change. Net Zero byreleased in Mayoutlines a possible roadmap for the global energy sector to achieve net zero emissions by mid-century.
In the roadmap, the amount of energy provided by nuclear nearly doubles between and To achieve this, new capacity additions reach 30 GW per year in the early s. Whilst absolute supply from nuclear increases, its relative contribution to the electricity mix decreases from about would raise the costs of a net-zero emissions pathway and add to the risk of not meeting nuclear power plant essay goal.
Decarbonisation drives down the carbon intensity of electricity generation: it falls from grams of CO 2 per kilowatt-hour in to below zero in net terms around Innovative transportation technologies are gaining momentum and are projected to increase electricity demand.
Achieving this long-term deployment level will require construction rates for new nuclear capacity of 23 GWe per year on average between and nuclear power plant essay Electric vehicles will account for TWh, nuclear power plant essay.
ETP developed the earlier scenarios. Energy efficiency, renewables and CCS make the largest contributions to global emissions reductions under the scenario.
Under the 2DS scenario, some 22 GWe of new nuclear generating capacity must be added annually by Launching ETPthe IEA said: "A concerted push for clean-energy innovation is the only way the world can meet its climate goals," and that governments should help boost or accelerate this transformation. ETP developed the ETP scenarios. In the 2DS one which is the main focus, some 22 GWe of new nuclear generating capacity must be added annually by Launching the ETP report, the IEA executive director said: "Electricity is going to play a defining role in the first half of this century as the energy carrier that increasingly powers economic growth and development.
While this offers opportunities, it does not solve our problems; indeed, it creates many new challenges. In its edition of Energy, Electricity and Nuclear Power Estimates for the Period up tonuclear power plant essay, the International Atomic Energy Agency's IAEA's high case projection has global nuclear generating capacity increasing from GWe in to GWe byby and by In the high case, 4.
The IAEA's low case projection assumes a continuation of current market technology and resource trends with few changes to policies affecting nuclear power.
It is designed to produce "conservative but plausible" estimates. It does not assume that all national targets for nuclear power will be achieved. Under this projection, nuclear capacity decreases to GWe by nuclear power plant essay, GWe bynuclear power plant essay, before recovering slightly to GWe by These projections represent a drop from those presented in the edition of Energy, Electricity and Nuclear Power Estimates for the Period up towhere nuclear capacity increases from GWe in to inGWe inand nuclear power plant essay in in the high case.
On the other hand, the low case projections of the edition are higher than those of the edition, with GWe inin and in In the previous year, in its International Status and Prospects for Nuclear Power Report by the Director Generalthe IAEA aniticipated global nuclear generating capacity increasing to GWe by in its high case.
The International Status and Prospects for Nuclear Power report is planned to be published every four years. Earlier projections from the IAEA had suggested a significantly stronger growth outlook for nuclear energy. For example, in its annual Energy, Electricity and Nuclear Power Estimates for the Period to published in Septemberthe IAEA's low projection showed a nuclear capacity increase from GWe then to GWe in ; the high case for that year was GWe, in line with forecast growth in all power generation, nuclear power plant essay.
For it tentatively estimated Nuclear power plant essay and GWe respectively. allow nuclear power plants to operate effectively. Policies should support a level playing field for all sources of low-carbon power projects. In the near term, small modular reactors "could extend the market for nuclear energy" and even replace coal boilers forced into closure in order to improve air quality. The US Energy Information Administration EIA publishes an annual report called International Energy Outlook IEO.
Renewables increase at 2. Generation from nuclear is forecast to increase by 1. Bythe outlook sees China surprass the United States as the country with the most nuclear generating capacity. In IEOnuclear power and renewable energy are forecast to be the world's fastest-growing energy sources from to Renewables increase 2. Nuclear increases by 2. Generation from non-hydro renewables increases by 5. In the reference scenario, global installed nuclear generating capacity would increase from GWe in to GWe in Over this period, nuclear electricity generation would increase from TWh to TWh but its share of total global electricity generation will remain unchanged at around In the high nuclear scenario, the IEEJ says that nuclear in effect "becomes the base power source" for many emerging countries, nuclear power plant essay, such as Asian and Middle Eastern countries.
This scenario assumes that nuclear energy "will benefit from lower level costs, nuclear power plant essay, and that nuclear technology transfer will be properly made from developed countries of nuclear technology, such as Japan, to emerging countries. The IEEJ notes: "The development of nuclear in the future is significantly uncertain. It is not only due to countries' or regions' circumstances of energy, economy, and development level of social infrastructure, but also a matter of international relations.
In OctoberWorld Energy Council WEC published new scenarios developed in collaboration with Accenture Strategy and the Paul Scherrer Institute as The Grand Transition.
