The cost of these five clean energy technologies in the United States has decreased significantly

in September 2016, the U.S. Department of energy (DOE) released the energy revolution 2016 report, which pointed out that thanks to DOE's investment support for the development of clean energy technologies for many years, more and more Chinese enterprises will participate in the exhibition in Poland, The costs of the five major clean energy technologies (including wind turbines, utility scale PV, distributed PV, electric vehicles and LEDs) have decreased significantly (the highest cost drop since 2008 reached 94% and the lowest reached 41%), and the deployment scale in the United States has expanded dramatically

1. Onshore wind power

in the past 40 years (years), DOE has supported a total of about US $2.4 billion for wind power technology research and development to reduce the cost of wind power and promote the wide non-linear characteristics of wind power. The stiffness and static arc height deviation of leaf spring under the specified load shall comply with the provisions of Table 1. In 2015, the cost of onshore wind power in the United States has dropped by nearly 41% compared with 2008, and the cost of wind power in some states has even dropped to 2 cents/kWh, which is very competitive. Compared with 2014, the installed capacity of wind power in the United States increased by 12% in 2015, accounting for 41% of the new electricity in the United States, and wind power accounted for 5% of the total power generation in the United States. The total installed capacity of wind power tripled compared with 2008; Among them, the installed wind power capacity of public utilities increased by 74000 MW, enough to meet the power demand of 17million households. For example, in 2015, thanks to the rapid increase of wind power installed capacity, carbon emissions in the United States decreased by 132million tons, saving 73billion gallons of water

2. Large scale photovoltaic power generation

since 2008, Eastman Chemical Company of the United States has developed a new generation of copolyester materials to be used in infant hearing echo detection equipment. The installation cost of large-scale photovoltaic power generation has decreased steadily. By 2015, it has dropped to $2.08/watt, a decrease of more than 64%, making it as competitive as traditional power generation in some parts of the United States. Driven by the decline in costs, the installed capacity of large-scale photovoltaic power generation in the United States showed explosive growth: in 2015, the installed capacity of large-scale photovoltaic power generation in the United States increased by 43% over 2014, accounting for 15% of the new electricity in the United States last year, and the cumulative installed capacity reached 13900 MW; In 2015, the national large-scale photovoltaic power generation reached 23billion kwh, enough to meet the power demand of 2million households. Meanwhile, in the first half of 2016 alone, large-scale photovoltaic power generation reached 15billion kwh, an increase of 34% over the same period. Thanks to the large-scale deployment of large-scale photovoltaic power generation, carbon emissions in the United States were reduced by 17million tons in 2014, saving 7.6 billion gallons of water

3. Distributed photovoltaic power generation

distributed photovoltaic power generation adopts the same photovoltaic technology as large-scale photovoltaic power generation. The difference is that the location of the distributed photovoltaic power generation system is more flexible, free from geographical restrictions, and covers a small area, which can be used for both domestic and commercial purposes. Since 2008, the installed cost of distributed PV has dropped by 54% to US $4.5/w, greatly reducing the threshold for use. In 2015, the new installed capacity of distributed photovoltaic systems in the United States exceeded 3110 MW, an increase of 34% over 2014. The cumulative installed capacity reached 11638 MW, with a total generating capacity of 12billion kwh, which can meet the power demand of 1.1 million American households. Distributed PV can turn traditional power consumers (individuals, families, schools, etc.) into power producers, with great development potential

4. LED lighting

with the progress of technology, the cost of LED bulb installation and use has become lower and lower. By 2015, the cost has decreased by 94%. In 2015, the number of LED bulbs installed in the United States exceeded 200million, an increase of 160% over 2014. Moreover, the existing LED bulbs have been improved by new technologies, and their energy consumption has been reduced by 85% compared with the old products. According to the prediction of the U.S. Department of energy, LED lamps will account for 85% of the sales of all lighting lamps by 2035, which will save 75% of the lighting energy consumption, and the annual energy cost will reach 630billion US dollars

5. Electric vehicles

since 2009, the cost of battery modules for electric vehicles has dropped by 73%. Affected by this, the sales of electric vehicles in the United States continued to rise. As of August 2016, the cumulative sales of electric vehicles in the United States exceeded 490000, and the number of charging piles deployed exceeded 3500. Battery prices once limited the popularity of electric vehicles, but now they are falling rapidly. Over the past 20 years, the US Department of energy has invested US $1billion in the research and development of electric vehicle batteries, which has improved battery performance, reduced costs and created us $3.5 billion in economic returns for the United States
