Producing electricity is traditionally
Electrical energy production is one of the inescapable needs of every developed country and one of the most polluting. The biggest problem is that electricity cannot be stored, and therefore must produce at the same time it is consumed.
Although there are other ways of producing electricity in industrial production is based on a single technology: can we turn a turbine connected to a generator. But to move the turbine requires a primary energy source. There are two basic ways to produce electricity, hydro power and thermal power.
Hydroelectric production consists of passing large amounts of water at high pressure through a turbine. Is a technology that requires a major intervention in space, because you need large quantities of water dam and have significant slopes? Has the advantage that it is a renewable primary energy and produces no emissions into the atmosphere. However, the precise conditions are not everywhere, so the total production depends on terrain and rainfall conditions. In addition, his great contribution is the impound of water produces significant changes in the environment, and adjusts the next ecosystem. Technological advances in improving the efficiency of the turbines, allowing the creation of micro, which requires much less infrastructure. Currently a small hydroelectric plant does not need more infrastructure than the old water mills. Thus, the landscape of the riverbanks, villages and cities, is filled with this mini.
Thermoelectric production involves passing hot air under pressure through a turbine. The hot air is obtained by boiling water and this water there are two technologies the burning and nuclear fission. The central hot water is called burning power plants. Can use four types of fuel bastard, oil, gas or befoul.
1. – The burning of coal is expensive, efficient and highly polluting. In addition to the CO2 emitted into the atmosphere other very harmful compounds such as sulfur. Is a non-renewable fossil resource.
2. – The burning of oil is expensive, very effective and very clean. Generates a lot of CO2 that is released into the atmosphere. The oil that is burned in power needs to be refined, so that there is an intermediate industrial process also consumes energy and produces pollution. Is a non-renewable fossil resource.
The roof of the house that reduces energy use
These ingredients are energy efficiency, interior comfort and use of renewable energy. “In VELUX we join the interests of institutions and companies committed to sustainability and social responsibility, values that are the basis of our work. We are pleased to contribute to research and develop new solutions to achieve optimal levels interior comfort with minimum energy consumption.
In this new target VELUX launches two new initiatives: the first window of solar-powered roof, a product that makes use of current technology to improve comfort below deck and energy savings, and a new power-saving function, built in the remote window and solar power, which activates automatically the blinds and mosquito nets to protect from the sun at times of higher radiation.
Window solar-powered roof, transform solar energy into electricity through a photovoltaic cell located, quietly, at the top of the window. Both battery that stores electrical energy as the engine, are perfectly integrated into the window frame.
In addition, VELUX offers a handy kit that lets you convert a manual window opening in a new window powered by solar power easily and without cables.
The other new solution is the “Power Saver”, entered in the command window and solar power are a number of variables that take into account the local average temperature, orientation of windows, location, etc … building a tailored suit every home. When the program has been activated, the script automatically starts the predetermined times. The times have been established for sunscreen products (blinds and mosquito nets) will raise or fall depending on season and time of day.
For example, during the summer in southern sun protection products will be lowered at a specific time in the morning and evening rise, and vice versa in winter. Furthermore, control automatically distinguishes between weekdays and weekends.
How to challenge for the future of energy
The future in energy presents many challenges. The new world needs require more changes than ever in the sector, which faces in the coming years to a much more demanding, more aware of the environment and where renewable energies are set to play a role. Antonio Laden, president of Engages, spoke this morning in the New Economy Forum of the changes they will face energy companies, changes that pass through the increased demand, the need to reduce CO2 emissions and the ability to offset the fall in oil stocks, the main source of energy today.
“The energy authorities require us more competitive, more sustainable and safer. With this in mind, we must ensure an efficient energy mix and economically viable. You cannot miss no coal or nuclear energy or gas or, obviously, renewable energy. Should be incentives for producers of renewable den backup, and ensure that prices reflect real costs, “very conscious with the new reality. Also invited all citizens to make this brainstorming exercise. “The best energy is not consumed,” he said, appealing to the awareness for greater savings.
At European level, has spoken of Energy 2020 plan to strengthen Europe’s energy networks and solidarity between producers. Laden shares the idea of linking, without which it would be very difficult to make progress towards this target. That is why Engages already working with France to build a pipeline to quadruple the current capacity of interconnection with the neighboring country, as well as other agreements to be looking for connections to the east but also to the south. “The connection with Algeria is necessary, but need not be unique.” As for Sonatas, said that as carriers the relationship is good, and is optimistic about the sector in the medium term.
Engages, he said, is a carrier independent backbone operators, neutral, trying to give the same service to everyone and has an international (in fact, over 50% of its investors are foreigners). Not willing to change that because it recognizes that in a globalize world would be meaningless, and maintains its level of investment prospects: 700 billion through 2014. “The international financial sector believes in us and will continue to.”
performance of Latin American Energy Organization Secretary
From 26 to 27 November in Managua, Nicaragua, the five Regional Energy Integration Forum (FIER), as part of earlier efforts at the 41st Meeting of Ministers of the Latin American Energy Organization (OLADE).
At the close of business, which included members and delegations from the public, private and international cooperation of 26 countries that make up OLADE, the organization’s executive secretary, Carlos Flores, noted that regional integration is not that is achieved with a formula, but there “to make it day by day.”
Flores presented the results of this international forum, highlighting that “integration in the region is feasible” and that technological and economic complementarily, solidarity and mutual aid “are vital to its consolidation.”
OLADE executive secretary also demonstrated the need to implement strategies in which “win all” and pointing to an energy matrix based on renewable sources (hydropower, biomass, geothermal, wind, natural gas).
The conclusions stressed the need to “advance the methods of contact with communities, highlighting the importance of the lessons learned in sustainable development projects, and assess the successful experiences in the field of electrical integration in the region (Mexico and Electrical Interconnection Central America and Mexico-Guatemala Electrical interconnection) “, while aiming to reduce the asymmetries between the countries of the region.
However, at no time mentioned the importance of communities, where emerging renewable projects (particularly hydropower), are part of this effort, as beneficiaries and fundamental part of any deal, negotiation, award, law or decree.
Why climate change is a global crisis
Climate change is an environmental crisis is basically one of the global crisis that most areas of society as it involves is closely related to model development, civilization cultures of the planet and energy models.
One of the issues related to climate change is energy, the energy matrices and the transition to less polluting models. It is therefore important to analyze the New Energy Strategy of World Bank Group plans to be implemented from 2011, because of their relevance in relation to climate change issues and their connections to the structure of the neoliberal system being implemented by one of the states with the greatest power in the world such as the World Bank.
The issue of energy is at the center of the climate change debate and the need for new paradigms of development. Gem’s energy strategy calls for “increasing access and reliability of energy supply, and facilitate the transition to a line of energy development more sustainable in environmental terms to developing countries based on” improving operational performance and Energy sector financing “and the” consolidation of good governance to enhance the contribution of energy to equitable economic development “and emphasizes improving the” good corporate governance. “The strategy, as it can not be otherwise, is based on market approaches and covers a wide range of sectors on which work including renewable energy, energy efficiency, hydropower, natural gas to generate electricity on a small scale and even mining.
Several expert analyses, networking and social organizations have begun to draw sharp criticism of the strategy concerned that the World Bank’s rhetoric contrasts with reality, since many of its projects are supported by the intensive use of fossil fuels or have huge environmental impacts and the rights of indigenous peoples such as large hydropower that the WB financed in Africa.
How energy-efficient devices for electrical development
“In less than ten years i.e. in 2018, the incorporation of energy efficient devices could slow the growth of electricity demand, achieving reductions in the order of 600 megawatts (MW),” said the Directorate General for Energy Efficiency (DGSE), Ministry of Energy and Mines of Peru (MEM).
The head of the DGSE, Luis Hero, said this would not be the only benefit, as this would also avoid the emission of 35 million tons of greenhouse gases produced by burning fossil fuels for electricity generation.
Wall
And is that because the country’s energy supply by 73% dependent on fossil fuels such as oil (51%), natural gas liquids (17%) and coal (5%), which are being looking not only pollutants but also expensive because they depend on international prices, the DGSE has designed a plan to boost renewable energy sources and energy efficiency.
He explained that energy efficiency itself constitutes a new source of energy as to reduce the volume of current consumption would also reduce the amount invested to import oil.
That is why he said Hero Azalea, projected that the sector as part of an ongoing process to improve the activities related to the generation / production, transportation, processing, distribution, marketing and use of energy sources over the next eight years could reduce national energy consumption by 15%.
“Making a calculation based on current, we can see that the annual savings to be gained in 10 years would be approximately 5 000 300 million U.S. dollars, with an estimated investment of 670 million U.S. dollars (an approximate ratio of 8 to 1)” said the head of the DGSE noting that the benefits go to the care of the environment.
How to model alternative energy generation
With the assistance of some 80 people took place in Tomcod Forum seminar in Chile mega hydroelectric real “alternative for a sustainable future? Whose main conclusion is that the country needs to develop alternative energy generation, which is not only based on water.
Juan Pablo Oregon, coordinator of the campaign Ecosystems and Patagonia without dams, Chile explained that currently requires a sustainable energy policy with a strong foundation for energy efficiency, which is cheap and attainable. It is therefore important to create a level playing field between different energy sources.
For his part, Roberto Roman engineer who discussed current developments in the energy matrix and the alternatives to mega-dams and power plants, said the trends in the world “takes over” intelligent network is the means that the claims are dynamically modulated to maximize resources and also have low emissions.
In this framework, also developed a forum on citizen and indigenous experiences of those affected by the energy mega projects and institutional responses, in which one of the panelists was Irene Romero Milieus Community Council, who explained that his community is planning a geothermal affect them seriously.
How research on solar thermal
The Higher Technological Institute “Catalina Harangue of Brown” runs the Laboratory for Research on Renewable Energy (LIP) since last September. The lip is possible through an agreement by which the National Agency for Research and Innovation (ANII) funds the project in which the UTU offers its premises and that one of them is in Montevideo and the other in Salt. In that sense, there are two people who are hired by the ANII, which are the engineer and technician Ramon Saul Vela Severe, in the area of research.
Within the UTU is working with students who are actively involved in the tasks you do in the laboratory. Consulted on this report, Saul Severe told PEOPLE that the laboratory “work with three types of energies that are most common in Salt: wind, solar photovoltaic and solar thermal. We also have an agro-meteorological station where measurements are made every day. “Severe confirmed that in both cases there are records of temperature, humidity, atmospheric pressure, rainfall, wind chill, and this occurs from August 10 this year.
“It connects a computer to the station and has all the information of every moment of the day, and then compared with measurements made on the panel, and there we have the performance results, how much radiation there, what temperature we have among other data, “appropriated.
According to experts, Salt is located in a geographical point where it gives more sun than the other places throughout the region, which encompasses the departments of Rivera, Arias and part of southern Brazil. According to Severe “solar map Salt located in a suitable, since it has an average of 5 kilowatt hours of sunshine per day during the year (and with that ability) are more than enough.
“With regard to wind energy, which is gaining ground Salt as it is building a plant of this system in the area of Salt Grande by a group of Japanese investors, Professor Severs told us that “with the measurements have done in the agro-meteorological station can say that is not profitable, because to move a small wind generator takes an average wind of 3 meters per second, and there is an average jump of less than 2 meters per second and not is not convenient.” The lips are planning to install a wind generator, which consists of a tower 20 meters high with a mill, along with eight photovoltaic solar panels of various models and types.
How the new energy strategy in 2020
The European Commission (EC) today introduced its new energy strategy up to 2020, which stresses the need to invest one billion euros in energy infrastructure over the next ten years and is committed to efficiency, expand agreements international and innovation. “To achieve an efficient economy, competitive and low carbon, we Europeanize our energy policy and focus on a small number of important priorities,” he said in a press conference on EU Energy Commissioner, Günter Hettinger.
In communication, non-legislative document, launched today, the Commission sets out five priorities on which develop during the next 18 months specific legislative initiatives, which will also help the leaders’ summit of EU energy to be held on 4 February, said the EC.
The first point of the strategy focuses on energy saving in transport and buildings, for which Brussels will propose incentives and financial instruments to foster investment and renewal in these areas.
He also noted that the public sector should consider energy efficiency when awarding construction or purchase services or products.
Secondly, the Commission has set a deadline for the realization of a true internal energy market, so that all member states involved before 2015.
The commissioner recalled that in the next ten years would be necessary to invest one billion euros in energy infrastructure in the EU.
“In the future will need the triple investment to build new networks and maintain the existing ones,” he said, and noted that would otherwise not meet the environmental objectives and requirements of EU consumption.
To promote the delivery of key strategic projects the EC proposes to simplify and expedite the granting of building permits, setting a deadline to final approval and European funding.
“The quality and capacity (current) are not sufficient for what we are required by the European market,” said Hettinger, who stressed the importance of private investment for construction and maintenance of energy plants and parks and community support for fund planning studies.
The Commission also proposes that the Twenty are “one voice” in global energy, and to coordinate their energy policies with third countries.
How primary energy supply 2010
The 2009 results show some remarkable changes compared to 2008. First, it was observed that the total primary energy supply, i.e. the total amount of energy used by the country to carry out all activities within their borders, decreased by 3.8% over the previous year.
Furthermore, we observed a decline in final consumption sectors, i.e. energy useful for actual applications, which reached 2.4%.
When this information is analyzed in more detail, we can see that this decline is explained mainly by decreases in consumption of industrial and mining sectors and transport, at 3.2% and 4.2% respectively. The only consumer sector showing a slight increase, showing greater resilience to the fall in economic activity is commercial, public and residential, with a positive variation of 2%, which, however, not enough to compensate the fall in consumption of the other two.
It should be noted that this drop in consumption is mainly reflected in the consumption of petroleum and coal, tools that natural gas consumption increased significantly with the coming into operation of the degasification of liquefied natural gas (LNG). Additionally, increased domestic production of primary energy by 6.8% (although less satisfying than a third of total consumption), and reduced total energy imports by 8.8%.
On this occasion, the information presents substantial improvements on previous years; it expanded both the number of surveys requested information. In particular, there was information of enterprises or production facilities to double the number of surveys conducted in previous years. Moreover, the detail of information requested grew to analyze better the penetration of certain technologies such as wind or biomass and the use made of energy.
“The changes respond to a policy outlined by the Ministry of Energy that seeks to improve the quality and coverage of the statistics generated to provide better information to citizens and to meet international requirements in this area. In particular, the country’s accession to the OECD and the recent application to the International Energy Agency (IEA), necessitate the need to build statistics with the highest standards of quality, “said Energy Minister, Ricardo Rainer.
Since October, the Ministry also started officially delivered on a regular basis (monthly and quarterly), information to the International Energy Agency (IEA) on production and consumption of oil, coal, gas, electricity and heat, as well as information prices, especially fuel. The requirements imposed by the release of this information, will require continued efforts to strengthen statistical capacity within the Ministry.
