Finding Solutions To The Climate Crisis

by Al Gore, former Vice President of the U.S.A., Nobel Peace prize 2007

Example of improvement in the efficiency in motors developed in Germany at BMW. Turbosteamer recycles waste heat to power the crankshaft. Step by step we can improve the efficiency of all a car, and even reduce its level of pollution.

Solutions are multiple (II)

First, dramatic improvements in the efficiency with which we generate, transport and use energy will almost certainly prove to be the single biggest source of sharp reductions in global warming pollution. 

Because pollution has been systematically ignored in the old rules of America's marketplace, there are lots of relatively easy ways to use new and more efficient options to cheaply eliminate it. Since pollution is, after all, waste, business and industry usually become more productive and efficient when they systematically go about reducing pollution. After all, many of the technologies on which we depend are actually so old that they are inherently far less efficient than newer technologies that we haven't started using.

One of the best examples is the internal combustion engine. When scientists calculate the energy content in BTUs of each gallon of gasoline used in a typical car, and then measure the amounts wasted in the car's routine operation, they find that an incredible 90% of that energy is completely wasted.

One engineer, Amory Lovins, has gone farther and calculated the amount of energy that is actually used to move the passenger (excluding the amount of energy used to move the several tons of metal surrounding the passenger) and has found that only 1% of the energy is actually used to move the person. This is more than an arcane calculation, or a parlor trick with arithmetic. These numbers actually illuminate the single biggest opportunity to make our economy more efficient and competitive while sharply reducing global warming pollution.

To take another example, many older factories use obsolete processes that generate prodigious amounts of waste heat that actually has tremendous economic value. By redesigning their processes and capturing all of that waste, they can eliminate huge amounts of global warming pollution while saving billions of dollars at the same time.

When we introduce the right incentives for eliminating pollution and becoming more efficient, many businesses will begin to make greater use of computers and advanced monitoring systems to identify even more opportunities for savings. This is what happened in the computer chip industry when more powerful chips led to better computers, which in turn made it possible to design even more powerful chips, in a virtuous cycle of steady improvement that became known as "Moore's Law." We may well see the emergence of a new version of "Moore's Law" producing steadily higher levels of energy efficiency at steadily lower cost.

There is yet another lesson we can learn from America's success in the information revolution. When the Internet was invented ­ and I assure you I intend to choose my words carefully here ­ it was because defense planners in the Pentagon forty years ago were searching for a way to protect America's command and communication infrastructure from being disrupted in a nuclear attack. The network they created ­ known as ARPANET ­ was based on "distributed communication" that allowed it to continue functioning even if part of it was destroyed.

Today, our nation faces threats very different from those we countered during the Cold War. We worry today that terrorists might try to inflict great damage on America's energy infrastructure by attacking a single vulnerable part of the oil distribution or electricity distribution network. 

Windmills in Colorado. 44 turbins produce 30 MW of electricity.

So, taking a page from the early pioneers of ARPANET, we should develop a distributed electricity and liquid fuels distribution network that is less dependent on large coal-fired generating plants and vulnerable oil ports and refineries.

Small windmills and photovoltaic solar cells distributed widely throughout the electricity grid would sharply reduce CO2 emissions and at the same time increase our energy security. Likewise, widely dispersed ethanol and biodiesel production facilities would shift our transportation fuel stocks to renewable forms of energy while making us less dependent on and vulnerable to disruptions in the supply of expensive crude oil from the Persian Gulf, Venezuela and Nigeria, all of which are extremely unreliable sources upon which to base our future economic vitality. It would also make us less vulnerable to the impact of a category 5 hurricane hitting coastal refineries or to a terrorist attack on ports or key parts of our current energy infrastructure.

Just as a robust information economy was triggered by the introduction of the Internet, a dynamic new renewable energy economy can be stimulated by the development of an "electranet", or smart grid, that allows individual homeowners and business-owners anywhere in America to use their own renewable sources of energy to sell electricity into the grid when they have a surplus and purchase it from the grid when they don't. The same electranet could give homeowners and business-owners accurate and powerful tools with which to precisely measure how much energy they are using where and when, and identify opportunities for eliminating unnecessary costs and wasteful usage patterns

A second group of building blocks to solve the climate crisis involves America's transportation infrastructure. We could further increase the value and efficiency of a distributed energy network by retooling our failing auto giants ­ GM and Ford ­ to require and assist them in switching to the manufacture of flex-fuel, plug-in, hybrid vehicles. The owners of such vehicles would have the ability to use electricity as a principle source of power and to supplement it by switching from gasoline to ethanol or biodiesel. This flexibility would give them incredible power in the marketplace for energy to push the entire system to much higher levels of efficiency and in the process sharply reduce global warming pollution.

This shift would also offer the hope of saving tens of thousands of good jobs in American companies that are presently fighting a losing battle selling cars and trucks that are less efficient than the ones made by their competitors in countries where they were forced to reduce their pollution and thus become more efficient.

It is, in other words, time for a national oil change. That is apparent to anyone who has looked at our national dipstick.

Our current ridiculous dependence on oil endangers not only our national security, but also our economic security. Anyone who believes that the international market for oil is a "free market" is seriously deluded. It has many characteristics of a free market, but it is also subject to periodic manipulation by the small group of nations controlling the largest recoverable reserves, sometimes in concert with companies that have great influence over the global production, refining, and distribution network.

It is extremely important for us to be clear among ourselves that these periodic efforts to manipulate price and supply have not one but two objectives. They naturally seek to maximize profits. But even more significantly, they seek to manipulate our political will. Every time we come close to recognizing the wisdom of developing our own independent sources of renewable fuels, they seek to dissipate our sense of urgency and derail our effort to become less dependent. That is what is happening at this very moment.

The future of motor is without any doubt the "green car". Here are BWM i8 hybrid (coupé) and the electric model i3 available since 2014. A leader to follow.

Shifting to a greater reliance on ethanol, cellulosic ethanol, butanol, and green diesel fuels will not only reduce global warming pollution and enhance our national and economic security, it will also reverse the steady loss of jobs and income in rural America. Several important building blocks for America's role in solving the climate crisis can be found in new approaches to agriculture. 

As pointed out by the "25 by 25" movement (aimed at securing 25% of America's power and transportation fuels from agricultural sources by the year 2025) we can revitalize the farm economy by shifting its mission from a focus on food, feed and fiber to a focus on food, feed, fiber, fuel, and ecosystem services. We can restore the health of depleted soils by encouraging and rewarding the growing of fuel source crops like switchgrass and saw-grass, using no till cultivation, and scientific crop rotation. We should also reward farmers for planting more trees and sequestering more carbon, and recognize the economic value of their stewardship of resources that are important to the health of our ecosystems.

Similarly, we should take bold steps to stop deforestation and extend the harvest cycle on timber to optimize the carbon sequestration that is most powerful and most efficient with older trees. On a worldwide basis, 2.5 trillion tons of the 10 trillion tons of CO2 emitted each year come from burning forests. So, better management of forests is one of the single most important strategies for solving the climate crisis.

Biomass whether in the form of trees, switchgrass, or other sources‹is one of the most important forms of renewable energy. And renewable sources make up one of the most promising building blocks for reducing carbon pollution.

Wind energy is already fully competitive as a mainstream source of electricity and will continue to grow in prominence and profitability.

Solar photovoltaic energy is‹according to researchers‹much closer than it has ever been to a cost competitive breakthrough, as new nanotechnologies are being applied to dramatically enhance the efficiency with which solar cells produce electricity from sunlight‹and as clever new designs for concentrating solar energy are used with new approaches such as Stirling engines that can bring costs sharply down.

Buildings both commercial and residential represent a larger source of global warming pollution than cars and trucks. But new architecture and design techniques are creating dramatic new opportunities for huge savings in energy use and global warming pollution. As an example of their potential, the American Institute of Architecture and the National Conference of Mayors have endorsed the "2030 Challenge", asking the global architecture and building community to immediately transform building design to require that all new buildings and developments be designed to use one half the fossil fuel energy they would typically consume for each building type, and that all new buildings be carbon neutral by 2030, using zero fossil fuels to operate. A newly constructed building at Oberlin College is producing 30 percent energy than it consumes. Some other countries have actually required a standard calling for zero carbon based energy inputs for new buildings.

The rapid urbanization of the world's population is leading to the prospective development of more new urban buildings in the next 35 years than have been constructed in all previous human history. This startling trend represents a tremendous opportunity for sharp reductions in global warming pollution through the use of intelligent architecture and design and stringent standards.

The current state of pollution in some industrial areas and large cities is alarming. When we know that each human breathes 15000 liters of air each day, we have good reasons to worry about the health of our planet. Documents Air-zone et Eidolons.

Here in the US the extra cost of efficiency improvements such as thicker insulation and more efficient window coatings have traditionally been shunned by builders and homebuyers alike because they add to the initial purchase price even though these investments typically pay for themselves by reducing heating and cooling costs and then produce additional savings each month for the lifetime of the building. It should be possible to remove the purchase price barrier for such improvements through the use of innovative mortgage finance instruments that eliminate any additional increase in the purchase price by capturing the future income from the expected savings. We should create a Carbon Neutral Mortgage Association to market these new financial instruments and stimulate their use in the private sector by utilities, banks and homebuilders. This new "Connie Mae" (CNMA) could be a valuable instrument for reducing the pollution from new buildings.
