Taiwan energy solutions: the full replacement of lighting LED energy saving a nuclear four plant

The global market research agency said green energy research department, if the four Taiwan nuclear construction, nuclear power plant in 2018 and decommissioned, and in 2021 two nuclear plant decommissioning, 20 years Taiwan will face challenges of power supply shortage, so how to respond as soon as possible future electricity demand growth, take other alternative energy solutions in energy saving and safely under consideration, or make full use of existing coal-fired power plants, and improve the power efficiency and reduce pollution is a pressing matter of the moment.

Lighting fully replace LED section power over a nuclear four plant

At present, the global lighting electricity consumption accounted for the proportion of about 19%, converted into electric power consumption of up to 2651 TWh, if the use of existing energy-saving lamps to replace the lighting device efficiency of the existing system, will be able to save 30% of lighting energy consumption. In the future, if lighting is combined with intelligent circuit environments, such as LEDS, sensors and embedded power control software, it is possible to save more than 30% of the energy consumption. Estimated that by 2030, the overall LED lighting applications will save more than 50% of energy consumption.

Taiwan current lighting systems accounted for Taiwan power consumption is about 17%~18%, if the LED lighting penetration rate of 20% can save about 2.56% of electricity consumption, when the power capacity of a nuclear power plant unit in 50%, about 6.39%, probably more than half of the four nuclear. If 100% are replaced by LED lighting to replace, can save about 12.78% of the electricity consumption, probably close to the nuclear power plant with a nuclear power plant capacity of the first plant, or more than a nuclear power plant capacity of four plants in the capacity of about two.

Due to the luminous efficiency of LED lighting technology continues to improve, the future is expected to have better energy efficiency. At present, the global multinational gradually set 20%, 30%, 60% LED lighting replacement ratio of the target, it is worth learning. Taiwan should be more active in the subsidy and promotion plan to LED lighting penetration rate of 30% as a short-term goal, the overall market is expected to Taiwan electricity efficiency will play a role.

Solar power generation has limited land available in Taiwan and effective sunshine is a problem

Taiwan in 2012 exports of solar cells is about 5500MW, but the local installation of grid connected solar power generation system is only 10MW, accounting for 0.007% of total electricity generation in Taiwan. According to the projections of the EnergyTrend data, if you want to replace nuclear plant four 2700 MW solar generating capacity, estimated to effective sunshine Taiwan, requires a minimum of installed capacity of up to 10GW, can the same and four nuclear plant efficiency reached, because nuclear power plant is 24 hours of operation, but also the capacity of the solar power station in Taiwan only the number of available daily sunshine hours of 4 hours (the relationship between the angle of the sun), if you want to use the tracking system, the cost will be higher.

10GW installed capacity, the cost of solar modules is about 240 billion yuan, plus the cost of construction and land costs, 10GW solar power station needs about NT $one trillion, that is, each 100MW needs $10 billion. At the same time, each 100MW needs at present about 200 hectares of land, if you can replace the 10GW solar power plant built four nuclear, the land area of about 20 thousand hectares, about 200 square kilometers, equivalent to 7.7 of the land area of Mailiao six. However, EnergyTrend said that the future of solar modules will continue to improve the efficiency of the system, so the same capacity required area will be reduced in the future.

In addition, the solar power station in Taiwan is also faced with heavy rain, typhoons and other climate considerations, the number of effective sunshine is relatively small. So the solar system in Taiwan, may not be large-scale implementation, should be more active to grant to the roof solar power system facelift for many families, and the reward area of solar power plant construction, effective management of renewable energy price.

In contrast to Europe and the Middle East, where the solar system is built, the former is the benefit of a large number of financial subsidies, the latter of which is a combination of full daylight and huge amounts of money. EnergyTrend pointed out that in Saudi Arabia, for example, has launched a huge solar power system construction due to enhance the efficiency of solar power generation module and the cost per unit area of the future prices are expected to decline, coupled with the country's full sunlight for solar power, climate, and low available land area large, expected benefits of good.

In addition, Europe, Greece, Italy, because of the debt problem, proposed the supply of sufficient sunshine land to build solar power plants, power generation in Germany, France, Central Europe and other regions, in order to repay the program. Countries in Europe also aim at full sunshine and cheap land resources in North Africa, actively build solar power stations, and then transferred to Europe and North Africa to use locally.

Actively open source but also to solve the trade barriers to expand the proportion of gasoline and gas power generation

TrendForce believes that at this stage of Taiwan wind, solar and biomass energy, including the use of other renewable energy sources still have room for development and improvement. While both thermal power facilities improved, such as clean coal technology (CCT) should also be considered (Taiwan existing coal-fired power plants produce 942 grams per kilowatt carbon emissions, fuel per unit of electricity produced 835 grams of carbon emissions), and relatively lower carbon emissions of combustion gas (Natural Gas 420 grams per kilowatt carbon emissions) power generation in Taiwan though is the main power, but should continue to expand the proportion of thermal power in Taiwan, the environmental impact caused by the relatively small.

Recently, because of the development of shale gas in the United States, has become the world's relatively low cost of power generation countries, East Asia, Japan has been the purchase of shale gas pre
