The idea that solar power will soon be everywhere is more than just environmental activists.
Sober utility economists are now working on cost forecasts and come to the conclusion that it might have been considered crazy a few years ago.
Prices have been plunging.
In many places, solar energy is now cheaper than coal, and in less than a decade, solar energy may fall below wind and natural gas and become the lowest --
Cost options are available almost everywhere.
But the key to balance is not just price.
Innovations like solar panels, doubling roof tiles, and advances in battery technologies that need to eliminate electricity flow during night and cloudy days, offset solar subsidiesS.
It\'s the fossil fuel cheerleader.
On January, President Donald Trump filed a complaint against a bankrupt Chinese, imposing a 30% tariff on imports of solar panels. owned U. S.
Manufacturers have accused China of illegally dumping panels in the United StatesS. market.
Tariffs are lower than many in the industry worry and are not expected to significantly slow the growth of solar energy in the US market. S. growth.
China has the largest number of installations worldwide, followed by Japan.
India has $160 billion in solar ambitionspower projects.
Some big companies, including Apple, have made notable announcements.
It plans to spend $0. 85 billion on solar energy. Also eye-
Tesla\'s glass roof tiles at Elon Musk
Sales began in 2017.
These tiles, similar to terracotta warriors or slabs, are located at the top of standard solar cells and can be combined with the home battery pack sold by Tesla as part of Musk\'s drive to make solar energy a part of everyday life. And utilities —
Now, they want to build and own the farm themselves, because it allows them to increase their income while evaluating it through construction costspayers.
Overall, installed capacity in the United StatesS.
In 2016, while investment in solar projects fell by 17, it increased by 50% to more than 41 gigawatts. 4 percent —
Reflects how much purchases per dollar have increased as prices have fallen. The U. S.
But other countries have made more breakthroughs in commercializing solar cells.
Bell Labs, New Jersey, made its first photovoltaic cell in 1953.
For decades, solar energy has only made economic sense on satellites.
Oil companies invested in photovoltaic cells that turned sunlight into electricity after the oil crisis in 1973, and then withdrew when crude oil prices plunged in 1980.
In the 1990 s, when Sharp, Kyocera and Sanyo produced most of the world\'s batteries, Japan has kept the industry alive.
Germany introduced an expanded feed system in 2004.
Price contracts that require utilities to pay for excess electricity generated by consumers using renewable energy for electricity generation.
Revenue from tariffs has led to a sharp increase in solar installations, with Germany leading the world in solar energy for several years
Tariff patterns have been replicated in other countries, so many new solar-
Panel manufacturers rose rapidly after a price war.
This caused the collapse of the panel price.
And the concentration of the industry in China, in China, the company led by Suntech electric power Holding Co. , Ltd.
Building large panel factories with government loans and cash from foreign investors
Support, enabling them to survive in wines that shut down many manufacturers elsewhere.
Nevertheless, the increase in the number of installations has brought the total number of solar workers in the United StatesS.
373,000, twice as much as coal.
Environmental group Greenpeace has long believed that solar energy can meet the world\'s energy needs.
Bloomberg New Energy Finance expects solar energy to account for 29% of global power capacity in 2040, up from 4% in 2015. Fossil-
Fuel proponents say photovoltaic power generation will never be a practical energy source because it cannot work when the sun does not shine.
Supporters of solar and wind power say the storage technology needed to deal with fluctuating production is not far behind.
Utilities and regulators make decisions based on decades
In the eyes of many in the electricity industry, the increasing political will to deal with climate change means that even without a price advantage, energy that does not emit carbon will become more and more important.
In many places, the debate about solar energy has gone from whether it should be cultivated through subsidies --
They are being phased out almost everywhere.
For issues that once seemed minor, such as how much solar users should contribute to the cost of maintaining the grid.
A development seems to convey the feeling of a turning point: on April, a coal company in Kentucky announced that it would seek to transform an abandoned open-air coal mine into the state\'s largest solar farm to return former miners to work
