Developing green technologies for the future in 2011
The launch of hybrid cars or the various forms of recycling were an important part of the agenda of countries in Latin America and the rest of the globe. However, in terms of technology becomes very still premature to speak of an effective “green revolution.” This is because beyond recognizing the benefits of more sustainable development in these areas of production, yet there was no impact on the daily lives of all people.
Is 2011 the year that effectively encourage and invest in the realization of more sustainable practices? Experts say it’s all about to change and next year is shaping up as one of the most promising for the advancement of green technology.
In mid-2010 and was hailed as a record production and sales of green technology (thus considered to be produced through alternative energy sources produce no pollution at the same performance). But experts say that in 2011 it will become more important because different proposals entrepreneurs can implement them with the help of government agencies or private companies.
According to BBC World, the Consumer Electronics Association of America (CEA) and Claremont Creek Investment Fund, agree that the coming months will be conducive to the ecology and technology increasingly go hand in hand.
One of the main points so it will be possible to reach higher consumption and therefore to greater production of such green products, environmental awareness is that every day is set up in more people. Thanks to the steady spread of issues related to global pollution and how sustainable development can help against this, consumers will increasingly turning to products that are developed taking into account its impact on the environment.
This is not an easy task because of one day to another is not possible to change the habits of each resident. However, as Jessica says Booth of CEA, this trend is slowly growing: “The idea of adopting the green is no longer a foreign concept to consumers. In fact over the years have implemented green practices in their lifestyles, such as recycling or avoiding plastic bags at the supermarket. “
This growing awareness of consumers, coupled with incentives that many governments are providing for the development of green technologies, suggests that next year will grow sustainable initiatives and people will receive them with increasing enthusiasm. Hopefully this time the forecasts are tipping to the side of sustainability.
Growing World energy demand is years 2030
As you can see in this year, The answers are encouraging and challenging – and vary widely at national and regional. Updated every year, the ExxonMobil Outlook analyzes the trends that will shape the global supply and demand of energy in the coming decades.
In the OECD energy demand flat. Developed economies belonging to the Organization for Economic Cooperation and Development (OECD) need energy to fuel continued economic recovery and growth. However, despite economic growth, energy demand in the OECD will be essentially unchanged until 2030.
The fundamental driver of this result is greater efficiency energética.Y efficiency, combined with a shift to cleaner fuels, emissions will decline significantly in the OECD by 2030.
Among non-OECD countries, China will lead a spectacular rise in energy demand and the growing prosperity of its large population is reflected in trends such as the properties of vehicles and increased consumption of electricity in general. Yet in 2030 the per capita energy consumption in non-OECD countries will remain much lower than in OECD countries. The efficiency gain will not be enough to offset this increase in demand and therefore CO2 emissions in countries outside the OECD will continue to increase until 2030.
ExxonMobil expects global energy demand in 2030 will grow about 35 percent more than in 2005. The growth in demand would be much higher – with a 2030 energy consumption almost double 2005 levels – if not for the expected improvements in energy efficiency.
We will have to continue to expand energy sources available to meet this substantial increase in demand. These sources include oil, natural gas and coal, which in 2030 will continue to meet about 80 percent of world energy demand.
Modern renewable fuels – wind, solar and biofuels – will expand significantly. The coal will decline sharply in OECD countries, but remain the dominant fuel for power generation in countries outside the OECD.
Technology will continue to evolve and play a key role in increasing efficiency, expanding supply and mitigation of emissions. These three elements must be pursued with vigor and perseverance in order to fulfill our rational use of energy and global environmental challenges.
The importance of energy for our lives
Before the Industrial Revolution all the energy used was renewable, watercourses, wind, wood and animals. The problem with the direct use of these energy sources is the need to locate the factory just where they are, because, in general, can not be transported. This greatly limits the industrial development, since you can not have these sources at the site of our interest, or when we want.
With the invention of the steam engine (James Watt, 1767) the industry is a source of energy that can be transported, by getting rid of that strict dependence. Release still is not complete, since it works with water and coal, and in regions where these resources are in abundance where the machine works better. This is the reason why the first industrial regions are located in humid areas with nearby coal mines: the Ruhr, England, Northern Appalachia and Asturias.
Freedom of final location is achieved in the twentieth century with the discovery of electricity management, which can create and transport over long distances and in large quantities. In addition, the lowering of transport allows other energy sources: coal, oil and gas, are used far from where they are extracted. Thus, when today we talk about energy sources we refer to two things, basically: oil, coal and natural gas on the one hand, and the production of electricity by another. Not that there are no other sources of energy, but its economic importance and the ability to influence the landscape is much lower.
Coal is used either directly or to produce electricity. Burned directly in heating and in some old industrial furnaces. Is destined to disappear. As the primary source for electricity production is used, but only in traditional mining regions. Burning coal produces many highly polluting waste and CO2, SO, and lots of dross.
