Cost of US Solar: 2010-2015


Cost of US Solar


Source:The Price of Solar Is Declining to Unprecedented Lows; Scientific American

Note: prices are installed cost per rated Watt of solar generating capacity (or $/WDC); the installed cost includes everything needed to get a solar power system up and running: the panels, the power electronics, the mounting hardware, and the installation itself

All categories of solar have seen significantly declining costs since 2010.  However, since these are median figures, low cost solar in one location doesn’t necessarily mean low cost solar everywhere in the country. The installed price can vary significantly.

Bolivia, one of the poorest countries in Latin America, has begun shipping lithium to China in what is considered the first step towards fulfilling its ambitions to becoming the world’s No. 1 exporter of the commodity. Lithium is used in high-tech batteries for such devices as smart phones and electric cars.

Australia is on track to become the world’s largest liquefied natural gas (LNG) exporter by 2019.

The issue of whether Iran will participate in the OPEC crude oil “production freeze” meeting that is to take place in Algiers in late September is still up in the air. Iran’s refusal to participate in a similar freeze last spring led to the collapse of the meeting. Iran does not expect to reach what it considers to be its rightful level of production within the next month suggesting that it will not agree to any freeze. Considering the increasing level of hostility between Iran and the Sunni Arab states in the region, it seems highly doubtful that it will be a party to any freeze agreement.

Iran says it is about to start its natural gas exports to Iraq next month. The new pipeline will initially supply some 7 million cubic meters of gas a day to power plants around Baghdad, but this will expand to 70 million when the pipelines are opened to Basra next year. The Iranians have been seeking export markets for their increasing production of natural gas which is way beyond what they can consume domestically. One plan involves piping gas to Qatar where large liquid natural gas (LNG) compression plants are already in operation. Other plans involved piping the gas to the European Union via Turkey.

Last week Columbia University’s Center on Global Energy Policy called Venezuela “a growing supply risk for the crude oil markets in 2017.”  The implications are that the South American country’s oil industry could come to a complete halt thereby removing another 2.1 million barrels per day from the global market. This would likely be enough to bring global oil markets into balance and push crude oil prices substantially higher. Investment in the oil industry has declined in recent years and the number of oil rigs in operation has dropped by a third in the last year.

By next year, 20% of US crude oil production is expected to come from the Gulf of Mexico.

McKinsey & Company look at the new economics of energy storage. Efficient and cost-effective energy storage could allow intermittent power sources such as renewables to play a base load role in energy delivery. The US government is leading the way in research and development to find solutions, funding 75 projects developing electricity storage. There are plans for hydrogen bromide, zinc-air batteries, storage in molten glass, next-generation flywheels, to name but a few with many claiming “drastic improvements” that can slash storage costs by 80–90%. The potential for industry is huge; Mckinsey estimates the energy storage market will grow a hundredfold to $90 billion a year by 2025.

According to Space Safety Magazine, about 75% of China’s electricity is now produced by coal-fired power plants, but a typical coal train of more than a kilometre long, carrying 5,000 tonnes of coal, could be replaced by just 40 grams of helium-3 (He-3), dramatically reducing transportation costs. Just eight tonnes of He-3 in nuclear fusion reactors would provide the equivalent energy of one billion tonnes of coal, burned in power stations. He-3 is extremely rare on Earth, but exists in abundance on the Moon, and the Chinese leadership has already begun an ambitious program to acquire it. Professor Ouyang Ziyuan, the chief scientist of the Chinese Lunar Exploration Program says the Moon is so rich in He-3, mining it could “solve humanity’s energy demand for around 10,000 years at least.” It is estimated that reserves of helium-3 across our planet amount to just 15 tonnes. The Moon, on the other hand, has reserves estimated at between one and five million tonnes. See China’s Helium-3 Program: A Global Game-Changer and China Is Winning the 21st Century Space Race.

India’s Ministry of Shipping is in the process of installing solar and wind based electric power systems at major ports across the country. By next year it plans to construct 90.6 megawatts  (MW) of solar energy capacity at the nation’s 12 major ports and 70 MW of wind energy capacity at four major ports. The projects are a part of the Green Port Initiative launched by the Ministry of Shipping designed to reduce the cost of power at these ports.

The US state of New York announced it will aim to generate half of its electric power requirements from renewable sources by the year 2030. The plan will rely on large subsidies to nuclear power plants to help reduce the state’s reliance on fossil fuels. In the first two years, the nuclear subsidies will total an estimated $965 million, a figure that could grow to $7.6 billion over 12 years.  Currently the state generates about a quarter of its energy from renewable sources.

There are reports Uber will be rolling out specially modified, self-driving Volvo XC90 SUVs in the US city of Pittsburgh later this month. Uber riders that end up with with one of these self-driving Volvos will be getting a free ride for the time being. The new LIDAR-equipped Volvo XC90s are not autonomous per se as they will be chaperoned by a human driver who’ll be able to take over in case of problems, and by a co-pilot in the passanger seat who observes. A number of cameras, radar, and GPS receivers feature in the new vehicles’ self-driving sensor suite in addition to the LIDAR. (LIDAR is a surveying detection system that works on the principle of radar, but uses light from a laser.)

The MIT Technology Review explains why range anxiety for electric vehicles is “overblown”. A new study by researchers at The Massachusetts Institute of Technology found that currently available electric cars in the US could replace 87% of the existing passanger vehicles on the road and still get drivers where they need to go (and back again). Assuming battery technology improves in line with government estimates, by 2020 up to 98% of these vehicles could be replaced.

In the US, the California Energy Commission has approved a pilot program in which piezoelectric crystals will be installed on several freeways. About the size of watch batteries, the crystals give off an electrical discharge when they’re mechanically stressed, such as when a vehicle drives over them. When driven over by thousands of vehicles an electric current is generated that can be harvested to feed power to the state grid. Scientists estimate the energy generated from piezoelectric crystals on a 10-mile stretch of freeway could provide power for the entire city of Burbank (population: more than 105,000).

Last week, Russia’s ambassador to Iran revealed Ukraine will no longer be a major energy route to Europe. Russia has plans for a new route which will sidestep Ukraine. In an interview Levan Jagarian said:  “We now have a new project and a new energy route through Turkey and Greece to southern Europe. This would effectively set aside Ukraine as a player in energy security.”
