In 1991, a national wind resource inventory taken by the U.S. Department of Energy startled the world when it reported that the three most wind-rich states —North Dakota, Kansas, and Texas— had enough harnessable wind energy to satisfy national electricity needs. Now a new study by a team of engineers at Stanford reports that the wind energy potential is actually substantially greater than that estimated in 1991.
When Austin Energy, the publicly owned utility in Austin, Texas, launched its GreenChoice program in 2000, customers opting for green electricity paid a premium. During the fall of 2005, climbing natural gas prices pulled conventional electricity costs above those of wind-generated electricity, the source of most green power. This crossing of the cost lines in Austin and several other communities is a milestone in the U.S. shift to a renewable energy economy.
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.
Climate change is no longer controversial; it has been accepted as scientific fact by a global consensus of researchers and policy makers, including the Bush White House, which resisted acknowledging human activities were a vital contributing factor, until recently. Now the Nobel committee selecting the Peace Prize laureate has raised the issue of warming posing a major international security crisis.
Peak oil is described as the point where oil production stops rising and begins its inevitable long-term decline. In the face of fast-growing demand, this means rising oil prices. But even if oil production growth simply slows or plateaus, the resulting tightening in supplies will still drive the price of oil upward, albeit less rapidly.
Few countries are planning a reduction in their use of oil. Even though peak oil may be imminent, most countries are counting on much higher oil consumption in the decades ahead, building automobile assembly plants, roads, highways, parking lots, and suburban housing developments as though cheap oil will last forever.
