Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources. But increasingly the story is about the plummeting prices of renewables, especially wind and solar. The cost of solar panels has dropped by 80 percent and the cost of wind turbines by close to one-third in the past eight years.
In many parts of the world renewable energy is already a principal energy source. In Scotland, for example, wind turbines provide enough electricity to power 95 percent of homes. While the rest of the world takes the lead, notably China and Europe, the United States is also seeing a remarkable shift. In March, for the first time, wind and solar power accounted for more than 10 percent of the power generated in the US, reported the US Energy Information Administration.
President Trump has underlined fossil fuels – especially coal – as the path to economic growth. In a recent speech in Iowa, he dismissed wind power as an unreliable energy source. But that message did not play well with many in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation – and where tech giants like Microsoft are being attracted by the availability of clean energy to power their data centers.
The question "what happens when the wind doesn’t blow or the sun doesn’t shine？" has provided a quick put-down for skeptics. But a boost in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.
The advance is driven in part by vehicle manufacturers, who are placing big bets on battery-powered electric vehicles. Although electric cars are still a rarity on roads now, this massive investment could change the picture rapidly in coming years.
While there’s a long way to go, the trend lines for renewables are spiking. The pace of change in energy sources appears to be speeding up – perhaps just in time to have a meaningful effect in slowing climate change. What Washington does – or doesn’t do – to promote alternative energy may mean less and less at a time of a global shift in thought.

However, many advantages the industrial society brings us also have a down side. One of the adverse effects of industrialization is acid deposition due to power plants, fossil fuels and automobile emissions. Acid rain is the popular term but the scientists prefer the term acid deposition. Acid rain can have adverse effects on the environment by damaging forests and lakes, making it too difficult for many plants and animals to live.
Charles Angus Smith, an Englishman, was the first to suggest, in 1852, that sulfuric acid in Manchester, England, was causing metal to rust and dyed goods to fade. One source that causes acid rain is fossil fuel. This energy source contributes 23.1 million tons of sulfur dioxide and 20.5 million tons of nitrogen oxides to our atmosphere worldwide. When fossil fuels are ignited, such as oil and coal, they release carbon dioxide, a so-called greenhouse gas that traps heat within the earth's atmosphere, which causes global warming. Also, they release sulfur dioxide, nitrogen oxide and metals such as mercury, aluminum into the atmosphere, which later can be carried a long distance from their source and be deposited as acid rain.
Forests are a complex ecosystem that involves trees, soil, water, the air, climate and other living organisms that support the community of wildlife: animals, birds, insects and plants. The countries most affected by acid rain are in Europe. Central Europe faces a much greater threat since it has a large amount of forest area and about 8% of German's forest face the lethal effect of acid rain. Acid rain kills about 50 million hectares of forest. Acid rain does not kill trees outright but weakens them to the point where they become susceptible to extremes of heat or cold, attacks from blight-causing or from inserts, and other environmental stresses.
When acid rain falls into lakes and rivers, it destroys all living things and populations of fish, aquatic plant life and microorganisms decline. Fish just goes extinct because they simply fail to reproduce and become less and less abundant, until they die out.
The result of acid rain is not only the destruction of forests and lakes, but also the corrosion of buildings and monuments. Almost every building of a major urban or industrial centre may be at risk from the corrosive effects of acid deposition and the rate of corrosion has increased dramatically in many urban areas. The Athenian monuments have got worst in the past 20～25 years as a result of pollution. Acid attack can also lead to stone decay through the creation of salt, which can crystallize and force apart mineral grains, causing the stone to disintegrate.
As our society gets more advanced, there is also the rising effect of pollution. To stop the effect we need to find alternative ways to remove or replace fossil fuel that is responsible for acid rain. The government needs to put stricter laws on the industries that pollute. People should find an efficient and alternative way to stop the pollution, because the effects of acid rain can be seen all round us, starling with forests and lakes, and in the heart of a city where the buildings and monuments are being eaten away by pollution.
According to the passage, acid rain is ______.
A．a source of pollution
B．an effect of industrialization
C．an advantage of industrial society
D．a deposition of fossil fuels
A．the growing seriousness of the pollution
B．the alarming effect of increased pollution
