100% clean, renewable energy is cheaper

A new analysis by Stanford University professor Mark Z. Jacobson and colleagues shows that the world can be powered by 100% clean, renewable energy, with today's technology.

The analysis looks at different pathways, using different ways of energy generation (by wind, water and sunlight), in combination with storage, transmission, and demand response, concluding that the world can also be powered by 100% clean, renewable energy at a lower cost than a BAU (Business-As-Usual) scenario dominated by fossil fuel.

“Based on these results, I can more confidently state that there is no technical or economic barrier to transitioning the entire world to 100% clean, renewable energy with a stable electric grid at low cost,” says Mark Jacobson.

Moreover, the price of fuel currently excludes the cost of health and climate damage caused by fuel. When including these costs, the cost of clean, renewable energy is ¼ the cost of BAU. Since clean, renewable energy uses 43%-58% fewer kWh, it is ⅛ the cost of fuel.

The price of fuel looks set to go up over time due to decreasing economies of scale for fuel and due to the cost of conflict associated with fuel. As an example, a 2017 report puts the cost of U.S. military intervention in Syria, Iraq, Afghanistan, and Pakistan over the period FY2001-FY2018 at $5.6 trillion, or $23,386 for the average taxpayer. The report adds that, unlike past US wars, these wars have been paid for largely through borrowing. The $5.6 trillion includes the interest the US has already paid on this debt, but it does not include projected future interest. Even if the US stopped spending money on these wars right now, cumulated interest costs on borrowing will ultimately add more than $7.9 trillion to the national debt over the next several decades.

Meanwhile, the price of clean, renewable energy looks set to keep coming down, in line with ongoing innovation, efficiency improvements and economies of scale. Examples are induction cooking, batteries, heat pumps, LED lights, refrigeration and smelters.

Local feebates can most effectively and rapidly achieve the necessary transition to clean, renewable energy. One example is to impose fees on sales of fuel, with the revenues used to fund rebates on local supply of clean, renewable energy. Another example is to impose fees on registration of vehicles with internal combustion engines, with the revenues used to fund rebates on registration of battery-electric vehicles. Local feebates can best help areas each get their preferred mix (of local supply/storage, of grid interconnection and imports/exports of electricity, and of demand response).

The Climate Plan calls for dramatic cuts in emissions through such policies, while also calling for further lines of action. For more on the benefits of feebates, see the feebates and policies pages.

100% clean & renewable energy is technically feasible and more attractive economically, more healthy, and will provide more jobs and more robust, stable and lower-cost energy with greater energy independence and security and with less need for land, water and imports. Moreover, it will dramatically reduce harmful pollution and emissions, which is absolutely imperative in the light of the urgent need to act on global warming.

Most Important Videos Uploaded In December 2016

Peter Wadhams is interviewed by Stuart Scott, Executive Director of United Planet Faith & Science Initiative, in this video called Farewell to Arctic Ice, uploaded December 27, 2016, and recorded at UN climate negotiations in Marrakesh, Morocco.

Peter Wadhams is an 'expeditionary' scientist and Emeritus Professor of Ocean Physics from Cambridge. Peter Wadhams' observations of the Arctic ice for over 4 decades makes him one of the worlds authorities on the subject.

In the video, Peter Wadhams discusses some of the issues described in his current book A Farewell to Ice (right), which is available as hardback or ebook (256 pages, published September 1, 2016).

Mark Jacobson gave a presentation called How the Future of Energy Impacts the Future of Our Cities, as part of the Digital Cities Summit, October 2016. The video was uploaded on 7 Dec 2016 by Stanford University School of Engineering.

Imagine a future where the entire U.S. energy infrastructure runs on clean, renewable energy. It’s possible to do it by 2050, says Stanford civil and environmental professor Mark Jacobson, and even without any new technologies. Mark Jacobson laid out the hidden upside of using solar, wind and water resources – rather than burning fossil fuels – to power everything from appliances and machinery to cars and building systems. “If you electrify everything, something magical happens. Without really changing your habits, you can reduce power demand by about 42%,” Mark Jacobson says.

Such a huge reduction in power demand comes mostly from the efficiency gains of electricity over combustion and eliminating the energy needed to mine, transport and refine fossil fuels. In addition to the pure energy savings, Mark Jacobson estimates that we could avoid 4 million to 7 million deaths from air pollution, eliminate $15 trillion to $25 trillion in global warming costs, create 17 million more jobs than would be lost if we don’t transition, and reduce the energy poverty of up to 4 billion people worldwide.

Paul Beckwith produced a two-part video, called 'Abrupt Climate Disrupting Arctic Changes'. The first part is at Part 1 of 2 and the second video, featured below, is at Part 2 of 2. The videos were uploaded on December 30, 2016.

In the videos, Paul Beckwith describes that gut-wrenching disruptions are underway in the Arctic, including record-high temperatures, near-record summer ice loss and spring snow cover loss, and record low sea-ice winter growth.

This second video is particularly interesting at the segment from 8:30 to 12:00 minutes, where Paul Beckwith discusses how wind patterns are changing over the Arctic and how this will make the Beaufort Gyre and other ocean currents reverse when we get complete sea-ice loss.

For more on this, see also the post Accelerating Warming of the Arctic Ocean.

Rapid Transition to a Clean World

100% clean and renewable wind, water, and solar (WWS)

all-sector energy roadmaps for 139 countries of the world

[ click here for explanatory video of above image ]

Above image is from an excellent study by Jacobson et al., showing that it is technically feasible and economically attractive to shift to clean energy facilities between now and 2050. This will create net jobs worldwide. It will avoid millions of air-pollution mortalities and avoid trillions of dollars in pollution and global warming damage. It will stabilize energy prices and reduce energy poverty. It will make countries energy independent and reduce international conflict over energy. It will reduce risks of large-scale system disruptions by significantly decentralizing power production.

Mark Jacobson: A 100 percent Renewable Economy

Given that there are so many benefits and there are no technical and economic barriers to complete a 100% shift by the year 2050 (and 80% by 2030), why not make an even faster transition?

Sam Carana suggests that feebates, especially when implemented locally, can best facilitate the necessary shift. Moreover, when energy feebates are implemented jointly with feebates in further areas, greenhouse gas emissions could be cut by 80% by 2020, while soils, atmosphere and oceans could be restored to their pre-industrial status over the course of the century.

[ the above emission cuts and feebates images were used in a meanwhile dated 2011 post ]

To achieve the most effective and rapid shift, Sam Carana recommends implementing two types of feebates, i.e. energy feebates and further feebates such as fees on sales of livestock products while using the revenues to fund rebates on soil supplements containing biochar.

Sam Carana adds that further lines of action will be needed to prevent Earth from overheating, warning that comprehensive and effective action is needed as described in the Climate Plan.

The image below shows that a shift to 100% clean (WWS) energy by 2050 (80% by 2030) could reduce CO2 to ~350 ppmv by 2100.

[ from Jacobson et al. 2015 ]

Energy feebates are the most effective way to speed up the shift to clean energy. Further feebates could make additional cuts in greenhouse gases emissions, while also removing carbon from the atmosphere and oceans, allowing us to aim for bringing down carbon dioxide levels in the atmosphere to 280 ppmv by the year 2100.
