Governments of several countries are committed to increasing the share of renewables in total energy supply.

Interstage In a two stage thermonuclear weapon the energy from the primary impacts the secondary.

Around 80 of the world s primary energy today is carbon based coal, oil, and gas.

In this protocell model, it's just an oil droplet, but a chemical metabolism inside that allows this protocell to use energy to do something, to actually become dynamic, as we'll see here.

Total energy consumed at all power plants for the generation of electricity was 4,398,768 ktoe (kilo ton of oil equivalent) which was 36 of the total for primary energy sources (TPES) of 2008.

The initial cost of the upgrade was US 60 million, funded primarily by the United States Department of Energy.

In 2008, 47.6 of Croatia's primary energy production structure comprised use of natural gas (47.7 ), crude oil (18.0 ), fuel wood (8.4 ), hydro power (25.4 ) and other renewable energy sources (0.5 ).

In Costa Rica, 92 per cent of power needs are generated by renewable energy sources, and the potential is not yet fully utilized.

Nuclear power, both fission based and fusion based, is yet another possibility for vast, reliable, secure, and environmentally safe primary energy.

About 80 per cent of world primary energy is supplied from fossil fuels, a finite resource.

This could potentially cover 5.5 per cent of Germany's energy needs.

Yes, Denmark gets a record 34 of its electricity from wind. But electricity accounts for only 18 of its final energy use.

In South Africa, nuclear power is the second largest source of electricity, accounting for 6.8 per cent of the country's electricity generation capacity and 3 per cent of the primary energy supply.

We are experiencing a step change in the growth rate of energy demand due to rising population and economic development.

In 2000, 88 per cent of Brazil's electricity was generated from hydropower.

Oil accounts for a large percentage of the world s energy consumption, ranging from a low of 32 for Europe and Asia, to a high of 53 for the Middle East.

UNICEF's estimation is that in developing countries 20 of the children of primary school age do not attend school, and another 30 drop out by grade 4.

This is due not only to the higher concentration of metabolizable energy in grain than in roughages, but also to the higher ratio of net energy of gain to net energy of maintenance where metabolizable energy intake is higher.

Brazilian firms have been investing mostly in primary industries such as energy and mining, led by Petrobras in oil and energy (UNCTAD 2004a).

The Chinese authorities have also introduced policies to reduce the proportion of coal in the country s overall energy mix.

Nuclear energy generated 16 per cent of the world's electricity with almost no greenhouse gas emissions.

Some adaptation will occur naturally, as rising energy and other commodity prices generate incentives to economize or seek alternatives.

Together, wind and solar energy supply a tiny fraction less than 0.6 of the world s entire energy needs.

While almost half of Africa's 53 countries could profitably produce hydropower, only 7 of this potential is reached because of poor infrastructure and the high costs of initial investments.

Super primes Primes with a prime index in the sequence of prime numbers (the 2nd, 3rd, 5th, ... prime).

The efficiency of a solar thermal collector is directly related to heat losses from the collector surface (efficiency being defined as the proportion of heat energy that can be retained for a predefined period of time).

So what is needed is massive public investment in cleaner energy provision, coupled in the short term with appropriate subsidies to offset high initial prices.

However, the ratio of resting metabolic rate to total daily energy expenditure can vary between 1.6 to 8.0 between species of mammals.

It feeds directly on minute phytoplankton, thereby using the primary production energy that the phytoplankton originally derived from the sun in order to sustain their pelagic (open ocean) life cycle.

It states that in a series of chemical reactions, the total energy gained or lost depends only on the initial and final states, regardless of the number or path of the steps.

The CO2 loss tells us the energy produced, if we know or can estimate the respiratory quotient (ratio of CO2 produced to oxygen used).

34 of men would like to pursue supplementary education in the fields of industry, power engineering and construction, whereas only 4 of women had the same preference.

This requires, inter alia, including the costs of externalities such as environmental degradation in energy pricing and using subsidies to bring down the initial costs of new technologies in order to make them more competitive.

The approval of the initial infrastructure costs does not imply endorsement of the proposal to appropriate a portion of up to 6 per cent of each new project budget for field office infrastructure.

Evaluation of initial proposals

I should be grateful if the present letter and the annexed Political Declaration of the International Conference for Renewable Energies could be circulated as a document of the General Assembly at its sixtieth session under item 54 (f) of the preliminary list.

World demand forecasts for 2005 and 2006 point to annual growth rates of 4 to 5 per cent, which would be just enough to accommodate the planned capacity additions.

The real fix to this problem will come when governments focus on research and development aimed at boosting the proportion of green energy sources in overall consumption.

Here are some of Damon's first impressions.

We are still in the very early stages.
