Is all this effort to save energy, the worth it?
Consider this. We had neglected energy efficiency from 1980 to 2010, the world's energy consumption would be 35 percent higher. What does that mean? Consider the amount of energy in the two largest economies in the world - the United States and China used. This is about how much energy the world saved.
This is published by the World Energy Outlook 2012, 12 November by the International Energy Agency. A report the stand up and take notice for all, in the energy efficiency industry, it not only explains what reaches the world, but also how far we can go.
"The year's World Energy Outlook shows that year 2035 corresponds to energy saving to reach almost one-fifth of global demand in the year 2010. In other words, energy efficiency is as important as unlimited energy supply and reinforced action on efficiency can serve as a unifying energy policy, the diverse benefits", according to the report.
The most interesting report notes that we halve growth in the global primary energy could use only low-cost technology that already exists. No gadget or Gizmo magic here is necessary.
"These gains are based not on any major or unexpected technological breakthroughs to achieve, but only on measures to remove the obstacles hindering the implementation of energy efficiency measures that are economical, among", according to the report.
If countries only stick on new policies that have already announced, see the world energy intensity gains of 1.8 percent annually a significant ramp up by 1 per cent per year over the previous 25-year period from 2010-2035. Energy intensity is an important measure, since it represents the energy efficiency to an economy - economic performance think of it as the amount of energy that it takes to a dollar in the to reach United States.
The report found considerable environmental benefits of energy efficiency. Also, 68 percent of the global CO2 savings will account for only stay with planned policies, energy efficiency.
What are the planned measures? China seeks energy intensity a reduction of 16 per cent by 2015. The United States have new fuel economy standards for the transport. Europe is a reduction of the energy 2020 20 percent consider demand. Japan is a 10-percent reduction in energy consumption by the year 2030 work.
How far-reaching these guidelines may seem, they scrape barely the surface of the potential energy savings. "Only a small part of the economic potential is used", according to the report. "The projection period four-fifths remain while the potential in the buildings sector and more than half of the industry is still undeveloped."
IEA offers a blueprint for further savings, he gets what "the efficient world scenario." Among other things, calls for energy efficiency to make more visible to consumers and prevent the sale of inefficient technologies by regulation better create financing methods.
If successful, it would blue print for oil by an amount equal to the current production of Russia and Norway together cut the demand. Global economic output rise by $18 trillion by 2030 - IEA says about what you get if you add today the economy of the United States, Canada, Mexico and Chile.
Which countries would benefit most? India would see 3 percent gain gross domestic product 2035; China 2.1 percent, the United States 1.7 per cent and Europe 1.1 percent, according to the 690-page report.
And what would the cost? The world should approximately 11.8 trillion $ in energy-efficient technologies to install, but the price less fuel extraction and transport, production of bio-fuels and construction of electrical infrastructure would be charged $17.5 of trillion less in fuel purchases and $5.9 trillion.
So is the energy efficiency is worth? The IEA figures there is - and then some.
