Ladies and gentlemen: There are times in the history of our nation when our very way of life depends upon dispelling illusions and awakening to the challenge of a present danger. In such moments, we are called upon to move quickly and boldly to shake off complacency, throw aside old habits and rise, clear-eyed and alert, to the necessity of big changes. Those who, for whatever reason, refuse to do their part must either be persuaded to join the effort or asked to step aside. This is such a moment.
Former US vice-president Al Gore is calling on the nation to marshal its resources and divorce itself from the combustible fuels economy. Gore says the US can produce all its energy requirements from renewable resources within 10 years, if concerted action is taken. The bold initiative is designed to drive debate on the topic and move discussions about how to deal with high fuel prices toward the new opportunity they provide for funding renewable infrastructure development.
EIA Report: Renewable energy consumption declined 1 percent between 2006 and 2007 to 6,830 trillion Btu, according to preliminary 2007 data. In contrast, both total energy and non-renewable energy increased 2 percent. There was wide variation in the consumption behavior of individual renewable energy sources. Hydro electricity dropped 14 percent in 2007 due to reduced precipitation in several regions of the country. On the plus side, biomass-based energy grew 7 percent and wind-generated electricity jumped 21 percent. Major increases in consumption of biomass to produce and use biofuels (ethanol and biodiesel) were almost entirely responsible for the increase in biomass during 2007.
Petroleum is the most pervasive base resource other than water in the global economy of the 21st century, and as demand is exploding, production is nearing its geological peak, and untenable price increases are hitting a strained economy hard. Oil prices could be in a stagflation lock, unable to readjust to consumers’ means, unable to compete as emerging energy sources repeatedly slash development and commercial prices. Whatever factors are at play, crude oil prices have jumped over 900% since 1998, and it looks like production cannot meet global demand.
As we search for a new way to fuel the global economy, in the midst of a rapidly spreading climate crisis, skyrocketing petroleum-based fuel prices and the likely imminent moment of peak oil production, it is instructive to look at the possibility that energy we already know how to access might be derived in (not cleaner, but) entirely clean ways. If we can find new sources of hydrocarbon fuels, can we access their energy content without burning them or emitting carbon?
The green technology transition is gaining momentum. Japanese auto manufacturer Toyota has announced it will add solar panels to some of its fleet of hybrid vehicles. The “high-end” third-generation Prius models will sport Kyocera-produced solar panels on the roof, aimed at assisting with powering the air-conditioning and other peripheral operations, freeing up battery energy to give the hybrid engines more non-combustion mileage.
The International Energy Agency has called for a major increase in the price at which carbon emissions are traded in carbon-offsetting schemes designed to reduce emissions. The IEA, as reported by the Financial Times, has called for carbon offsets to be priced closer to $200 per ton, in order to bring carbon-trading schemes in line with the costs of reducing emissions. EU carbon offsets are currently priced at roughly $43 per ton.
Food riots from Haiti to west Africa, Egypt and the Philippines, in recent weeks, have sparked concern among policy-makers, diplomats and economists, that the current state of the global food supply is so precarious that such violence will spread and political and economic instability could follow. Concerns about the American economy, home to most productive grain-producing region in the world, and a shift to biofuels there, could mean added difficulty in bringing food prices down.
As governments, businesses and scientists work toward creating cost-effective solutions for zero-emissions propulsion technologies, the possibility of a zero-combustion energy production and industrial fabrication model is emerging. Preservation of the natural environment and containment of emissions-induced global climate change both require new technologies that will allow full economic output, including industry and transport, that eliminate the need for combustible fuels.
The emergence of ecological economic trends, methods and industries, means that a wave of job creation could be the stabilizing factor which helps American industry recover both momentum and public appeal, potentially helping to ease pricing pressures and banks’ concerns about lending to individuals and small and medium-sized businesses.
The ongoing transition to an environmentally sustainable economy, focusing on energy and agricultural resources, is already opening the door to a range of new industrial and engineering services related to resource and ecosystem resilience (now understood to be vital to the stability of the natural environment whose own services underpin every element of our civilization).
The private investment fund Ceres, a group of institutional investors, has promised to devote $10 billion to investment in clean energy sources. The news comes as 3 of the world’s major oil companies call for coordinated policy on how to face climate change, constrain emissions, and a couple of months after 150 global corporations asked for a major boost in subsidized research into transitioning to clean energy technologies.
At a meeting of European scientists, in Stockholm, Sweden, the man who coined the term ‘anthropocene’ to describe the new geological epoch in which human influence dominates natural processes, announced that the term has gained acceptance in a growing number of fields. The real import of the term, and of its increasing relevance to what science is showing about the effects of human civilization on the environment, globally, is that ecological information is increasingly vital to implementing human ambitions in a responsible and sustainable way.
A new study has shown that raindrops can be used to produce electricity. The key is the mechanical energy of the raindrops, meaning the energy contained in their motion and in the way that force is diffused when striking a given type of surface.In this case the surface is PVDF (polyvinylidene diflouride) plastic, which is able to release a charge when temporarily “deformed” by mechanical activity, such as being struck by a moving object. A sheet of PVDF just 25 micrometers thick (1,000 = 1 milimeter) receives the impact of raindrops, and the effect is the release of energy, which can be harvested and turned into electricity.
A new breakthrough in propulsion technology may enable a fuel-free engine with no moving parts to use microwaves to push satellites through space and automobiles on earth. The science is complicated and controversial, but appears to be sound and takes advantage of Einstein’s landmark theory of relativity to turn contained microwaves into a propulsion system, in the form of a non-mechanical engine.
If you think you are spending more each week at the supermarket, you may be right. The escalating share of the U.S. grain harvest going to ethanol distilleries is driving up food prices worldwide. Corn prices have doubled over the last year, wheat futures are trading at their highest level in 10 years, and rice prices are rising too. In addition, soybean futures have risen by half.
Between the years 2008 and 2020, we are likely to see a still unimaginably sweeping shift away from fossil fuels and high-contamination modes of powering our economy. The transition will have a political component, but will be driven mostly by cost concerns, resource scarcity, and public demand for cleaner air and responsible climate policy, a demand which is not ideological in nature.
Due to the science we already have, the laws we have to govern our own activity and to force government to act for the public health, we face the real possibility of being forced, in American courts, in the future, to pay for damage done to the most affected populations in other parts of the world, as a result of inaction by our government. And if not in court, then as a matter of the de facto urgencies of international political stability.
Ecological advancement and retro-fitting will be the new boom economy. Let’s make sure we do everything possible to fund not only research, but implementation. What will it cost to produce an environmentally-oriented overhaul of the US economy, by way of the private sector, with government incentives, and to the ever-growing benefit of private sector interests? These are key questions being asked by scientists, activists, economists and politicians, not to mention energy industry executives and those whose core business involves fossil fuels.
Can the world prepare to face the potential economic fallout from increasingly intense weather phenomena, prolonged heat waves, desertification, ice-melt and flooding? While there is no clear proof Hurricane Katrina was a direct result of climate change, hurricanes of such intensity will become increasingly frequent as Gulf waters warm; the aftermath provides real instruction for just how fragile the social fabric can be in the face of natural disaster.
The Hot Spring connects people to brainstorm, solve problems, and build a more just, more sustainable future.
