New energy micro-grid to deduct a winner?

Polaris solar PV net news: according to the “confidence in the global economic and ecological program” malinuoer (Maryknoll) Office said with the increase of efficiency of energy storage and distribution, coupled with decline in prices of new energy technologies, the world’s energy system will undergo profound changes. Large utility companies that use fossil fuels, small-scale renewable energy producers are facing increased competition.

High in industrialized countries especially the United States, due to the increasing vulnerability of energy systems, turning to renewable energy sources to reduce dependence on fossil fuels is important. In less industrialized economies, this transformation can be dirty, centralized energy systems enabling those countries to cross directly into sustainable and distributed energy systems.

Micro-grid construction to promote United States power grid update

Ensia environmental publications, it was reported, a lithium-ion battery prices have fallen since 2010 40%, solar panels, a 80% drop in price than it was 5 years ago, wind power turbine has dropped from 2008, the highest price of 35%. With the increase of these factors, micro energy network built more and more convenience, economy, balance of different energy supply can be carried out smoothly and provides services such as voltage support, frequency tuning, but also can contribute to the larger network output profit from electricity, in times of emergency but also to provide electricity support. Most noteworthy is that of micro energy network operator, whether it be a college campuses, military installations, hospitals, or other unit, in the event of network failure can also be run.

This trend has come at the right time. Technology leader Massoud, Dean of Minnesota ˙ Amin said that the United States power grid needs updating, and significant increase in the number of weather-related incidents in recent years, “between 50 and 80 ‘s of the last century, 2~5 in blackouts every 2008-2012 year 70~130”. As climate change brings more severe storms, power continued to deteriorate, and this number will only increase. In addition to avoiding a wider power cuts, Amin also suggested economic considerations: through the implementation of the 2009 United States revitalization and Reinvestment Act, to the new smart grid investment of $ 2.96 billion, creating 47,000 full-time jobs to help accelerate the introduction of new technologies.

In the United States in some remote areas, have set up micro-grids, such as in the Islands, had been relying on expensive fossil fuel imports. Some micro-chip production facilities, such as hospitals, factories, military bases, unable to bear the risk of power outage. Noteworthy is that the main fossil fuel companies are building up their own renewable energy micro-grid, supplying offshore oil rigs.

Germany 31% nuclear power and green power replaces thermal power

Germany 2000, through the milestones of the renewable energy law, guaranteed renewable fixed within 20 years and higher than the market price, establishing incentives to invest in renewable energy, currently Germany is undergoing a rapid transformation of the energy system. This method marks the end of dependence on nuclear power, this was in Japan after Fukushima flatly decided.

In Germany southwest of Schwäbisch Hall city, energy structure including complex of can renewable energy has fast change, municipal utilities company management with near 3,000 a place energy supply who, respectively from thousands of a Sun PV device, and 2 a wind farm, and 1 a gas and steam station, and 6 a small hydropower station, and 3 a born material (wood business particles) power plant, and 6 a bio gas power plant, 48 a thermoelectric joint power plant, also including city outside general power and can renewable energy power supply who.

Only more than 10 years, the industrial engine of Germany with green electricity, has replaced about 31% of nuclear power and fossil fuels to generate electricity. Was done through dynamic, decentralized area flattened, including BLS small and medium producers of renewable energy – businesses, villages and towns, partners, individuals and farmers, green investment funds, and the numbers are increasing every month.

These changes are profound challenges to traditional energy companies, who is facing a so-called “death maneuver” began to lose customers, are forced to raise rates to make up for the loss of income, with the result that more workers to leave. In the course of these changes, control the production and distribution of energy Germany 4, most of the largest energy utility companies by surprise, experienced irreparable loss record. Since 2010, Germany’s largest E.On and RWE, two of the company’s net loss of one-third, “large companies could linger in the inevitable extra, otherwise they would have to turn to renewable energy as soon as possible.”

Africa’s rapid increase in solar PV

In less industrialized countries, this shift is under way in different ways. As of the Mother Jones article says, “like the mobile revolution in Africa, greatly reducing the fixed telephone line, solar is now skips the grid”, 19% of the world’s population with no access to electricity, but this ratio is the percentage of African 58%, a higher percentage in rural areas, such as Tanzania, the population without access to electricity 86%.

Millions of rural population in Africa did not wait for the big power grid construction of industrialized countries, they are using solar panels. Experts in development projects, said the rise of clean energy may partly be catalysts of economic development. 2009~2012 report of the World Bank noted that small-scale solar photovoltaic equipment sales increased almost 1 time per year in Africa, 2012 will sell 4.4 million devices.

Compared with the small distributed energy system is that the Obama Administration proposed “power in Africa” project, establish a centralized energy system relies on external cooperation, within 5 years, the African electricity production increased 1 time. United States says spent $ 7 billion for the project, but $ 5 billion of which is not to provide aid, but through the export-import Bank, the overseas private investment Corporation and other government institutions to provide loans to private companies. The project also includes private sector investments of at least $ 20 billion commitment.

The international business times contributor Jesse ˙ Fu Ting to “electricity in Africa” project questioned believed that the project was not to provide sustainable and affordable energy for Africa, but for United States companies to help, let them compete for dominance of Africa’s fast-growing economy. “Power in Africa” the final aim of the project is that Western private power companies permanent partnership with the African continent. GEC invested heavily in the project, has in recent years shifted its focus to Africa, because the project has pledged financial and insurance support, United States with Western companies can cooperate with Chinese firms compete’s growing influence in Africa.

But they may overlook the small innovative projects, these projects can transmit power to communities without power, it is especially important to those in rural areas far from the power supply. In fact, billions of dollars in projects, are provided only for the construction of micro-grid “off-grid energy challenge” project of $ 2 million, which suggests that “power in Africa” project priorities.
