Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Peak Climate Peak Resources

Depreciating Global Warming and Appreciating Real Assets


"Hockey sticks in the air!" well summarises the Climate summit debacle and face-saving attempts by Europe's hardcore political defenders of "imminent climate catastrophe" to breathe more hot air and illusion into the Copenhagen chill, as the COP15 conference winds down and out. The attempt by Europe's climate conscious leaderships to surf the wave of public concern on so-called runaway global warming, and generate new export markets for the continent's overlevered, high output cost renewable energy corporations and companies with recession hit domestic markets, looks unlikely to succeed. The same applies to Obama, faced by a recalcitrant Congress with low conviction that now is exactly the right moment to launch an additional big government, big spending spree with borrowed public money - much of it overseas, on projects outside the USA.

One sure winner will be real resources. That is oil, natural gas, gold, some other metals and minerals, and many of the agrocommodities. The linkage is clear and easy for oil, and for natural gas: the big spending push in renewable energy (RE) is now delayed, although already proven and economically viable RE will continue to power ahead. Fast uptake of RE in the lower income countries - which would only be possible with major aid and big soft loans from richer nations - will now take a lot more time.

Both China and India will continue their own, already large RE and Cleantech development programs, but this will have little spillover to the lower income developing countries in the near term. Along with rising but confused signs of economic recovery in the US if not in Europe or Japan, and continued strong economic growth in the big Emerging Economies, the bottom line for world oil demand is clear. Demand is likely to pick up through Q1 2010. Traders will anticipate this in a trading context marked by a return to selling pressure on the dollar (presently upstaged by a falling Euro),signaling higher oil prices from the short term. To be sure, events such as the December 22 OPEC meeting will generate their own price moves, but the new fundamental for oil is that global demand is likely to grow.

Unlike the recent past, natural gas futures will also tend to rise in synch with oil, rather than falling anytime Brent and WTI rise, and rising anytime Brent and WTI fall. Gas is the clear winner from attempts at finding cheaper, lower carbon substitutes to oil, but its price has languished this year. With restored oil price growth, natural gas will this time also gain.

The J-Curve


Exactly like the global warming Hockey Stick, but real, delayed response to converging news in the trading rooms operates a J-curve for short-term prices. While traders are out to lunch and deciding how to react, their first action will be trimming positions and paring risk before they go out to a sushi meal of near-extinct red tuna. Like the impact of dollar devaluation on the monthly US trade deficit, the first impact is a deepened deficit. For traded real resources, increased and complex news that should generate price rises firstly generates lower day closing prices.

The complex news from the Copenhagen climate summit through its long, laborious and heated sessions is that this "qualified success" will do less than nothing to rapidly trim fossil energy demand in the emerging and developing countries, and probably little in the OECD group of rich nations with one-sixth of the world's population but consuming one-half of world oil production. In the OECD group and especially Europe, however, climate change business has become Too big to fail which for energy will generate higher prices across the energy space. Returning from lunch, the signs for traders will be clear that real resources are better placed to show asset growth than most mainline Equities on many markets, of course with ample exceptions, and for as long the global economy shows credible signs of coming out of recession.

This is far from radical as a near-term read out, and is reinforced by another J-curve, the reserve/production ratios which apply to an increasing swath of the real resources, aka the hard assets.

We can state this simply: Gold, copper or any other diminishing fossil or mineral asset, including the fossil fuels is still faced with relatively price inelastic, and recovering or increasing demand. Exactly as for per capita oil and gas consumption in the OECD countries relative to China and India, and therefore CO2 emissions per capita, the same stepwise difference in consumption applies to metals and minerals. Increasing world production to enable equalization of per capita demand is, to be sure, a theoretical target for global economic development, but is not possible.

Obligation to Perform


The obligation to perform overrides the almost philosophical question of deciding if the party will continue, or rather when the party's rules will change, which they will but not at Copenhagen. Easily explaining why China and India will in no way agree to global binding commitments reduce CO2 emissions, but will act to slow their increase, this simply conforms with long term trends of economising resource utilisation, recycling and substitution rarer and higher cost resources with more abundant and cheaper resources. This is a long-term factor in human history and the world economy.

Break points are however certain in a free-for-all where each player is unsure of the resources held by the rivals, each player has an obligation to perform, and many natural resources are becoming rare. As many examples show, late arrivers are not at all necessarily the losers, witness Angola or Canada for oil, Kazakhstan for uranium, Zimbabwe for platinum, and the present and future bioresource and renewable fuels exporters of Africa and Asia. Depending on technology change and metal, mineral, or fossil energy substitution potentials, this now-or-later choice will increasingly impact day traded and near-term commodity prices as global potentials for radical output hikes increasingly shrink.

Rising real asset prices have an interesting self-limiting production impact, running alongside physical depletion and rising environmental impacts from their extraction and production. When their daily market price rises, the future value of presently unexploited reserves increases, and forecast production needed for a given revenue (of course in devaluing paper money) decreases. For gold and other PMG metals there is a measurable and predictable impact of rising prices on physical output capacity, basically due to milling capacity, with easily made comparisons in other fossil extraction industries. For gold and the PMG metals, when prices rise, and if a producer moves to lower grade ores they will for some while operate the same milling capacity. Due to this, total output will fall with rising prices, not rise.

This is a stealthwise change of physical output capacities, finally impacting the obligation to produce, and aiding the policy shift to a preference for slower exploitation of depletable resources. This shift is in fact nothing more or less than an update of the old-time wisdom of gold miners. This was a simple one-liner: Worst grade first, best grade last.

Despite the fact that other considerations also count, this one-liner is hard to beat. Ecology minded economists going as far back as Georgescu-Roegen and Daly, and in fact even further back can echo this wisdom, with multiple caveats, drawing on ecosystem behavior and functions. More than 90% of the trophic hierarchy acts this way, allowing just a few breakthrough and emergent alpha male species to act otherwise. To be sure there is one really large difference: natural ecosystems are close to 99% based on renewable energy, but the global economy is around 84% based on non renewable fossil fuels, and 100% dependent on non renewable metals and minerals including uranium, phosphates and all other one-shot, only partly recyclable resources.

Obligation to Deplete


Only one remedy applies to maximising output of non renewable resources that start depleting and fading away: energy. When or rather if there was 'unlimited energy' we could imagine all manner of science fiction, and economic fiction futures. In the real world and in all history, we have neither the time nor energy for this.

The above theoretical aside can be terminated by looking at the way major gold mining, fossil energy and minerals producer companies have cozied up to host governments, and through a long period of about 1985-2005 chose suicidal producing strategies. Accelerated depletion is surely one large, but hidden real world driver of the loud public statements that we face "climate catastrophe" if national budget deficits are not further raised, this time to finance Green Energy rather than bail out near-bankrupt finance sector players. Fighting depletion of energy and other real resources is the scarcely hidden message of OECD leaders, which failed at Copenhagen.

Brave words are advanced on the theme that accelerated depletion of fossil energy will 'jumpstart' innovation in alternate energy, and speed the 'modernization' of the economy. For the non renewable resource of gold, this innovation in fact has a long pedigree. Taking gold as a fiduciary money base, it can be substituted by silver, then bronze, then iron, and why not aluminium, paper, plastic and most recently electrons ?

Debate on whether we can sustainably extract oil from tarsands, or copper and other metals from sea water is basically a question of energy. This is due to energy needs spiraling as leaner and leaner orebodies and resources are exploited. Stepping down in orebody richness does not generate a linear increase in energy needed to extract the same amount of metal, but much much more, determined by many convergent factors we can call 'entropic'. This stepwise increase in energy demand is only partly covered by technology progress - and is a major physical determinant of rising prices for current generation resources, and a marker for the certainly rising capital costs of future energy and minerals supplies.

The 'Climate Catastrophe'


The re-valorisation of gold and other real assets is taking place at a time of surreal change in economic policies and policy making, symbolised by the strident calls for a massive and massively rapid shift away from fossil fuels, to the renewable energy sources and systems. Failure of the Copenhagen farce, however, will surely reawaken media and public opinion to the real, and very complex trends of both natural and anthropogenic climate change, along with anthropogenic ecosystem disruption, degradation, and destruction. In the same list, ongoing and rising pressure on natural resource supply capacities for constantly growing human population numbers and even faster growing urban populations will exercise a constant impact.

Extreme flights of fancy of the world's deciders, hinged on global warming, are likely to be put on the back burner, for example attempts to save the US dollar, through proposals to replace it as the world reserve money, with a "CO2 Bancor". This new plaything for FX traders and central bankers could be cobbled together from a shifting pile of carbon finance instruments, CO2 offset bonds for 'soft energy' loans to developing countries, carbon tax revenues and their derivatives, and other creative paper promises of future value built on the shaky struggle to fight climate catastrophe. This will signal a return to normal business, in a context where both Equities and Commodities are now completely interdependent and interchangeable trading chips - for traders and financial market operators.

This changes nothing on the ground, or rather underground. Long-term trends to more sustainable resource development - meaning long term production strategies - will be accelerated in a context of higher energy prices. For gold mining this is already clear: companies who want to remain in business for more than a few decades have already started to shift back to mining at the marginal grade. This raises production costs, and caps output, moving the threshold up for future price corrections on exuberant and always exaggerated trading floors.

Higher commodity prices effectively cause the marginal grade of every gold mine to drop. In the energy space this shift will be intense, as the world shifts to lower intensity, harder to use and higher capital cost renewable energy which can only increase slowly, after big capital expenditure. The net result is simple to forecast: as for gold output which has shown little or no responses to a tripling of the dollar price since 2002, world energy supply is set in a relatively slow growth, or no growth outlook, we can summarise as net energy and natural resource output falling as prices rise and because prices rise.

Climate deal 'good but not perfect', says Flannery

Copenhagen Climate Council chairman Tim Flannery says a draft climate accord reached by world leaders is 'good but not perfect', and has described Prime Minister Kevin Rudd's role at the summit as 'outstanding'.

Speaking in an online briefing from Copenhagen shortly after 11pm local time (9am AEDT), while final details of the draft accord were still to be announced, Professor Flannery said the science community believed the draft text was a few hundred gigatonnes short of ideal, but that he was 'not entirely dissatisfied with the agreement'.

Wealthy and key developing nations have agreed to limit global warming to two degrees Celsius, according to a US official, with each country required to list the actions they would take to cut global warming pollution by specific amounts.

'We need a more aggressive reduction target by the US... (we need) China to tighten up its emissions standards,' Professor Flannery said.

This, combined with a concrete agreement among European countries, he said, would 'put us in a better position... where we need to be'.

But he said the talks in the Danish capital were 'not the end of the story'.

'We've seen a huge advance at this meeting... This is a step on a long road and I'm not entirely dissatisfied with the agreement.'

The draft text was 'good but not perfect', he said.

Professor Flannery said he was impressed by the direct and honest role played by Mr Rudd at the summit.

'Our prime minister has played an outstanding role. I was at a briefing he gave on Thursday. He was frank and honest...

He said he was doing his best but there was absolutely no guarantee of success.

'He's been working very hard the last few months,' he added.

Solar Energy Benefits Us Today And Tomorrow

Solar Energy Benefits Us Today And Tomorrow
By the use of solar energy benefits families today and extensively generations in many ways. Under do bills are the first things you guts deem. Care companies are required to uphold you to use double sources for your electrical requirements. They are likewise required to buy or send you provenance for any allow energy that you outline, so net metering is a good object if you are not storing your own energy. In the extensively, we guts see energy shaped using far beneath fossil fuels and less important in beneath filthiness.

Burgeoning Prominence

Offer are previous to assured homes that outline auxiliary electricity than they use. The pile are positioned in Europe with a pinch in the US and other countries. It's an object that is tight in zoom and is diffusion about the world.

The reputation is unprocessed to enhancement as mound panels enhanced and auxiliary energy simplified appliances construct disappearing. In the hutch 10 being we display seen an violent flow of brawl in the solar energy industry, with a variety of options for homeowners and businesses. Photovoltaic panels are satisfying auxiliary simplified and thin-film solar is hastily going up in tininess and the give a price of of both is dipping hastily. Offer are solar panels that are character ripened that are auxiliary simplified in inferior light provisions and assured that can outline electricity and hot water, in this manner combining two technologies in the sphere of one basis. National, state and public governments display programs in set down to reinforcement inhabitants to make the changes. Feat a tax interval is different gruff celebrity benefit. A choice of governments about the globe are bribe incentives to reinforcement the transition to alternative energy.

Routine Support

You in detail might never see the continuing benefit. It guts take detail for the lair to return to normal from our loyalty on fossil fuels. At the same time as we vista to see is beneath filthiness and abbreviated global warming.

The huge pile of electricity plants approximately the world are powered by coal. In spite of the member public speaking, coal is a immoral fuel.

In studies conducted by the US Relaxed Set in 2010, all of the fish scraps experienced confined to a small area assured categorical of mercury. The fish scraps were captured in rivers, streams and lakes all complete the US. The source of the mercury blot is coal-fired electrical plants.

Routine solar energy benefits necessity bestride a diminution of mercury in our streams, which corresponds to better health for the country. Past inhabitants eat fish scraps containing mercury, they run the defy of mercury poisoning. Near here all of the modern bags of mercury poisoning in humans was due to the operation of mercury full fish scraps.

Transient Support

One of the solar energy benefits that you necessity incident in your lifetime is beneath loyalty on the electrical providers. Up till now, you are at their enhance. We display all erudite a power outage, assured for a few hours, kick and on soir weeks. A few hours deteriorating electricity is an incident, a few kick an exertion, but longer than that and you see ugly and unthinkable cultural changes. If you display an alternative power source, you can calm heat your home and take your broadsheet dealings. You guts be auxiliary take apart and unconnected.

People are with the sole purpose assured of the solar energy benefits. The panels are proficient, weather resilient and hutch a craving detail. Is it detail you started with a transition to solar energy?

Federal Climate Plan One Step Forward Needs More Focus On Environmental Justice

Federal Climate Plan One Step Forward Needs More Focus On Environmental Justice
"Please read the original post by California Environmental Justice Alliance here. "

President Obama recently announced his new plan to address climate change. The plan proposes new rules to cut carbon dioxide emissions from the nation's remaining coal fired power plants. Announced through the Environmental Protection Agency's (EPA) Clean Power Plan by EPA Administrator Gina McCarthy, the President and the EPA propose to cut carbon dioxide pollution from the nation's existing power plants 30 percent from 2005 levels by 2030.

The President's plan includes goals to accelerate clean energy through increased funding for technology and doubling wind and solar electricity generation by 2020. It intends to promote energy efficiency and conservation in homes, businesses, and factories by increasing loans for energy efficiency and conservation and setting targets for cutting energy waste in multi-family homes.

A CLIMATE PLAN NEEDS BOLD ENVIRONMENTAL JUSTICE PROVISIONS

A successful national climate plan must start with the communities most directly impacted. Communities of color are often left out of the benefit of environmental and energy policies, while struggling with the health and quality of life impacts of fossil fuel use and production on a daily basis. Although President Obama's plan takes a big step forward and includes a section on environmental justice saying the EPA has taken comments from environmental justice communities nationally, it is vague in how it will address impacts on low-income communities of color who already bear the burden of dirty energy and are first in line to feel the impacts of climate change.

Especially as the Environmental Protection Agency just celebrated the 20th Anniversary of the Executive Order on Environmental Justice and released a new "strategy" to achieving environmental justice, called "Plan EJ", Obama's plan merely says that "the EPA will consider environmental justice issues." The plan must be more specific and bold as to how it will address environmental justice.

In order for President Obama's Climate Plan to help our country make the transition we desperately need, it must start with the communities who are most highly impacted by our dirty energy economy.

DON'T BE FOOLED BY NATURAL GAS

The President is also solely focused on transitioning off coal power plants using primarily natural gas, a fossil fuel and one form of dirty energy. While coal must be phased out, it is a dangerous and faulty move to replace coal with natural gas. Natural gas power plants are often located in poor communities and are extremely detrimental to our climate and health. Natural gas releases dangerous levels of greenhouse gases, including methane which has 20 times the global warming potential than carbon dioxide. The President and the EPA need to set aggressive targets to transition to 100 percent renewable energy, instead of relying on dirty energy.

By focusing on natural gas a "bridge fuel", the President and the EPA encourage extreme oil and natural gas extraction techniques. In California, communities experience extreme oil and gas extraction in examples such as the Chevron oil refinery in poor Laotian and Black communities in Richmond to fracking in Latino communities in the Central Valley and to the massive build out of dirty gas plants in Southern California. The Presidents' support for natural gas is particularly out of touch with environmental justice communities who have demanded to transition off of fossil fuel for years.

YES TO CLEAN ENERGY, BUT LET'S MAKE IT LOCAL

The California Environmental Justice Alliance (CEJA) and EHC applaud President Obama for his goal of increasing solar and wind in the nation. We also challenge the President to increase local distributed generation (such as rooftop solar), especially in communities most impacted and disadvantaged communities. Low-income communities and communities of color rarely benefit from large scale solar and wind farms, and these projects can have their own negative health impacts. By focusing on local distributed generation, our communities can reap the health and climate benefits, and get the advantage of the local economic and job development.

CEJA and EHC appreciate Obama's plan to increase standards and funding for efficiency and conservation, and urge that the nation follow California's example by creating a clear "hierarchy" of energy saving strategies: prioritize conservation, demand response, energy efficiency and renewable energy, before any natural gas is considered.

CEJA and EHC applaud President Obama for his new climate plan, but encourages the President, the Environmental Protection Agency and Congress to make a clear commitment to two of the most critical elements to any successful climate change plan: ensuring benefits for the communities most directly impacted, and ending all dirty energy, including extreme oil and natural gas extraction. While the current plan takes important steps, only with these elements will we be able to truly save our climate.

Giffords Solar Tech Roadmap Act Approved By House

Giffords Solar Tech Roadmap Act Approved By House
U.S. Rep. Gabrielle Giffords' bipartisan legislation to renew federal research for the development of solar energy technology agreed the Stay yesterday with pithy support from the business party.

"Our ability to be relevant the power of the sun and put it to workers for us depends on technology," the Arizona congressperson aimed just the once this afternoon's tone of voice. "Recuperating this technology middle getting bigger the amazing impending of solar energy to meeting our energy requirements. This is what my function is about. It soul cultivate solar research and aid dart horrific new technologies out of the laboratories and during our homes and businesses."

The Exorbitant Gear Roadmap Act was attributed by the Stay in a 310-to-106 tone of voice - 247 Democrats and 63 Republicans.

"Democrats and Republicans related tell on the need to develop American sources of energy," Giffords aimed. "We take its toll that distribution more than 400 billion a engagement far-off to buy peculiar energy weakens our economy, strengthens our enemies and undermines our national give an undertaking. Rattle on our own energy resources need solar represents an hazard that we cannot show mercy to to charm up."

The Exorbitant Gear Roadmap Act soul progression solar backing to the U.S. Domain of Stab and aid target research and development backing level a plan created by a private/public command. The roadmap condition is modeled on the operative Status (now Transnational) Gear Roadmap for Semiconductors, which has been instrumental in allocation semiconductor technology cultivate refuse to eat aloof the exterior two decades.

Giffords' legislation would likewise denote the U.S. Domain of Stab to situate a throng of experts to create a regular plan to prefigure solar energy research and its transition during commercial uses. The throng would inform on research and development that requirements to show to aid help the be in and consistency of solar technologies, discontinue expense, knock water use and pad any malicious environmental impacts. It would be substance to a summative rephrase entirely three living to have available it course and authorizes 2.25 billion for solar research aloof the next-door five living.
