Sustainable Energy - The Future is Clear We Must Move Forward With SESustainable energy (SE), with it the future is clear, and much cleaner for that matter! There are several different definitions of this term, with energy efficiency and renewable energy being the twin pillars of SE. Effectively, the provision of energy such that it meets the needs of the present without compromising the ability of future generations to meet their own needs.
Energy which is replenish-able within a human lifetime and causes no long-term damage to the environment.
What makes energy that is sustainable different from other new renewable energy terminology like alternative energy, green energy, or green power, is that it focuses on the ability of that energy source to continue to provide energy, and also allows it to produce some pollution to the environment as long as it does not prohibit heavy use of the source for an indefinite amount of time. Green power is a subset of renewable energy and represents those renewable energy resources and technologies that provide the greatest benefit to the environment.
Renewable energy technologies are the essential contributors to SE as they generally contribute to worldwide energy security, reducing dependence on fossil fuel resources, and providing opportunities for controlling and reducing greenhouse gas emissions.
There are currently three generations of renewables technologies, reaching back more than 100 years. First-generation technologies emerged from the industrial revolution at the end of the 19th century and include hydropower, biomass combustion, and geothermal power and heat. Second-generation technologies include solar heating and cooling, wind power, modern forms of bio-energy, and solar photovoltaics.
Third-generation technologies are still under development and include advanced biomass gasification, bio-refinery technologies, concentrating solar thermal power, hot dry rock geothermal energy, and ocean energy. First and second-generation renewable energy technologies have already entered the energy markets, and third-generation renewable energy technologies heavily depend on long term research and development commitments, where the public sector has an important role to play. A 2008 comprehensive cost-benefit analysis review of energy solutions in the context of global warming and other issues ranked wind power combined with battery electric vehicles (BEV) as the most efficient, followed by concentrated solar power, geothermal power, tidal power, photovoltaic, wave power, coal capture and storage, nuclear energy, and finally biofuels. There are few signs that the urgently needed change in direction in global energy trends is underway.
Against this unpromising background, events such as those at the Fukushima Daiichi nuclear power plant and the turmoil in parts of the Middle East and North Africa (MENA) have cast doubts on the reliability of energy supply, while concerns about sovereign financial integrity have shifted the focus of government attention away from energy policy and limited their means of policy intervention, boding ill for agreed global climate change objectives.
Thirty-five years after the Agency’s founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate – but new energy-related concerns have arisen. This information paper accompanies the IEA publication Deploying Renewables 2011: Best and Future Policy Practice (IEA, 2011a).
It provides an account of the strategic drivers underpinning renewable energy (RE) technology deployment (energy security, economic development and environment protection) and assesses RE technologies with respect to these drivers, including an estimate of GHG emissions reductions due to RE technologies. The paper also explores the different barriers to deploying renewables at a given stage of market maturity and discusses what tools policy makers can avail of to succeed in removing deployment barriers.
An additional topical highlight explores the challenges associated with accelerating the diffusion of RE technologies in developing countries.
Moving towards energy sustainability will require changes not only in the way energy is supplied, but in the way it is used, and reducing the amount of energy required to deliver various goods or services is essential. Renewable energy and energy efficiency are sometimes said to be the “twin pillars” of a SE policy. Improving energy efficiency is one of the most constructive and cost–effective ways to address the challenges of high energy prices, energy security and independence, air pollution, and global climate change.

Increased efficiency can lower greenhouse gas emissions and other pollutants, as well as decrease water use. Improving energy efficiency costs significantly less than investing in new generation and transmission.
When integrated into energy resource plans, energy efficiency can provide long-term benefits by lowering baseload and peak demand and reducing the need for additional generation and transmission assets.
Energy efficiency also diversifies utility resource portfolios and can be a hedge against uncertainty associated with fluctuating fuel prices and other risk factors. The UN General Assembly is encouraging Member States and other actors to increase the awareness of the importance of addressing energy issues and to promote action at the local, national, regional and international levels. Every year hundreds of organizations and individuals in over 30 countries take part in EU Sustainable Energy week by hosting Energy Day events and activities that promote energy efficiency and renewable energy sources.
Be a part of it in 2012 by holding a SE-themed event, project or activity in Brussels or in your country between 18 and 22 June. There are many things we can do to promote and facilitate the growth of sustainable energy, and the easiest and simplest is energy efficiency and energy conservation.

If you have an idea on how to set a custom size in Epson LX 300+ can you post in this forum? I have job to develop reservation system for Training Center which have class room, dormitory, catering service, etc. I'd like to receive useful tips, tools and resources via email from Kelley Blue Book and affiliates. No matter how you look at it, it is one of the most critical aspects of us moving forward and keeping our existing way of life intact. To reduce the risks of runaway climate change, or reaching a tipping point in our climate, we must reduce our greenhouse gas emissions, which will mean renewable, clean energy sources.
On the other hand, low-carbon energy is different from SE in that low-carbon energy is only sustainable in the sense that it does not add to the CO2 levels in the atmosphere. The planet has a natural capability to recover which means pollution that does not go beyond that capability can still be termed as green. These are now entering markets as a result of research, development and demonstration (RD&D) investments since the 1980s.
Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushing CO2 emissions to a new high. It provides more detailed data and analysis on policies for Deploying Renewables, and is intended to complement the main publication. Opportunities for improvement on the demand side of the energy equation are as rich and diverse as those on the supply side, and often offer significant economic benefits.
Both resources must be developed in order to stabilize and reduce carbon dioxide emissions. Energy efficiency can also boost the local economy and create downward pressure on natural gas prices and volatility.
At the week-long event attendees learn from energy industry experts, policy makers, regulators and industry leading businesses.

Unfortunately, technology dictates that we need energy, but the sources of that energy are optional. Oil, coal, and gas are all finite resources as well, which makes them limited in their lifespans as energy sources, and as supplies dwindle, the cost to extract and use them increases in our current supply and demand economic models. Environmental Protection Agency (EPA) defines green power as electricity produced from solar, wind, geothermal, biogas, biomass, and low-impact small hydroelectric sources. The initial investment was prompted by energy security concerns linked to the oil crises (1973 and 1979) of the 1970s but the continuing appeal of these renewables is due, at least in part, to environmental benefits. And the industrialized nations of the world are no longer the only major consumers of energy. Efficiency slows down energy demand growth so that rising clean energy supplies can make deep cuts in fossil fuel use. We know we can’t change the world overnight, but we can make significant changes over time one person at a time.
We need it to fuel our transportation, heat our homes, power our computers, phones, lights, and other necessities. So it is huge that we eliminate our dependance on the fuels, not only for the enhancement of our planet and Eco-systems, but for our own health and well-being, not to mention probably adding more to our pockets and more jobs in the long run.
Customers often buy green power to avoid the environmental impacts of fossil based fuel supplies and its greenhouse gas reduction benefits. The number of people without access to electricity remained unacceptably high at 1.3 billion, around 20% of the world’s population. Climate change driven by greenhouse gas emissions – 60% of which derive from energy production or use – is a growing threat. If we all chip in and do our part, we can make for a healthier, cleaner planet to live on, which in turn will improve our quality of life and well-being, and make us and our future generations healthier, and happier! Currently we derive only 13% of our total electricity from renewable sources, and that doesn’t include transportation! Despite the priority in many countries to increase energy efficiency, global energy intensity worsened for the second straight year.
So energy policy was tasked with a new objective: to cut greenhouse gas emissions while maintaining economic growth. Likewise, unless clean energy supplies come online rapidly, slowing demand growth will only begin to reduce total emissions; reducing the carbon content of energy sources is also needed. Currently fossil fuels power most of our energy sources, in the form of coal and oil, or gas. Any serious vision of a SE economy thus requires commitments to both renewables and efficiency. These fuels produce greenhouse gas emissions which is a byproduct of their combustion, which by itself isn’t that harmful, but in the massive quantities we are using it, it is a big problem.
