Off-grid PV systems have traditionally used rechargeable batteries to store excess electricity. With grid-tied systems, excess electricity can be sent to the transmission grid, while standard grid electricity can be used to meet shortfalls. Net metering programs give household systems a credit for any electricity they deliver to the grid. This is handled by 'rolling back' the meter whenever the home produces more electricity than it consumes. If the net electricity use is below zero, the utility then rolls over the kilowatt hour credit to the next month. Other approaches involve the use of two meters, to measure electricity consumed vs. electricity produced. This is less common due to the increased installation cost of the second meter. Most standard meters accurately measure in both directions, making a second meter unnecessary.

Commercial solar water heaters began appearing in the United States in the 1890s. These systems saw increasing use until the 1920s but were gradually replaced by cheaper and more reliable heating fuels. As with photovoltaics, solar water heating attracted renewed attention as a result of the oil crises in the 1970s but interest subsided in the 1980s due to falling petroleum prices. Development in the solar water heating sector progressed steadily throughout the 1990s and growth rates have averaged 20% per year since 1999. Although generally underestimated, solar water heating and cooling is by far the most widely deployed solar technology with an estimated capacity of 154 GW as of 2007.

It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending on the way they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power and solar water heating to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

Question: What are the technologies used to capture solar energy characterized as? Question: What are some active solar techniques used to harness solar energy? Question: What is an example of a passive solar technique?
The large magnitude of solar energy available makes it a highly appealing source of electricity. The United Nations Development Programme in its 2000 World Energy Assessment found that the annual potential of solar energy was 1,575–49,837 exajoules (EJ). This is several times larger than the total world energy consumption, which was 559.8 EJ in 2012.

Question: What makes solar energy an appealing source of electricity> Question: Who estimated the annual potential of solar energy in 2000? Question: What is solar energy's yearly potential? Question: What was the total worldwide energy consumption in 2012?
In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries’ energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating global warming, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared".

Question: How will solar energy increase energy security? Question: What costs will solar energy lower? Question: What effect will solar energy have on the price of fossil fuels? Question: What should the cost of incentives for producing solar energy be considered?
The potential solar energy that could be used by humans differs from the amount of solar energy present near the surface of the planet because factors such as geography, time variation, cloud cover, and the land available to humans limits the amount of solar energy that we can acquire.

Question: Why does the amount of usable solar energy differ from the amount near the planets surface?
Geography effects solar energy potential because areas that are closer to the equator have a greater amount of solar radiation. However, the use of photovoltaics that can follow the position of the sun can significantly increase the solar energy potential in areas that are farther from the equator. Time variation effects the potential of solar energy because during the nighttime there is little solar radiation on the surface of the Earth for solar panels to absorb. This limits the amount of energy that solar panels can absorb in one day. Cloud cover can effect the potential of solar panels because clouds block incoming light from the sun and reduce the light available for solar cells.

Question: Why does geography have an effect of the amount of solar energy available? Question: What is the process called that can increase solar energy in areas further away from the earth's equator? Question: Why does time have an effect of the amount of available solar energy? Question: What effect does cloud coverage have on the amount of solar energy available?
In addition, land availability has a large effect on the available solar energy because solar panels can only be set up on land that is unowned and suitable for solar panels. Roofs have been found to be a suitable place for solar cells, as many people have discovered that they can collect energy directly from their homes this way. Other areas that are suitable for solar cells are lands that are unowned by businesses where solar plants can be established.

Question: Why does land availability have an effect on solar energy? Question: Why are roofs a good place for solar panels?
In 2000, the United Nations Development Programme, UN Department of Economic and Social Affairs, and World Energy Council published an estimate of the potential solar energy that could be used by humans each year that took into account factors such as insolation, cloud cover, and the land that is usable by humans. The estimate found that solar energy has a global potential of 1,575–49,837 EJ per year (see table below).

Question: What factors were taken into account in the estimate published in 2000 on solar energy? Question: What was the total potential of solar energy found in the estimate?
Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). CSP systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. PV converts light into electric current using the photoelectric effect.

A solar balloon is a black balloon that is filled with ordinary air. As sunlight shines on the balloon, the air inside is heated and expands causing an upward buoyancy force, much like an artificially heated hot air balloon. Some solar balloons are large enough for human flight, but usage is generally limited to the toy market as the surface-area to payload-weight ratio is relatively high.

Beginning with the surge in coal use which accompanied the Industrial Revolution, energy consumption has steadily transitioned from wood and biomass to fossil fuels. The early development of solar technologies starting in the 1860s was driven by an expectation that coal would soon become scarce. However, development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum.

Question: Why was solar technology developed in the 1860s? Question: What slowed the development of solar technologies in the early 20th century?
In 2011, a report by the International Energy Agency found that solar energy technologies such as photovoltaics, solar hot water and concentrated solar power could provide a third of the world’s energy by 2060 if politicians commit to limiting climate change. The energy from the sun could play a key role in de-carbonizing the global economy alongside improvements in energy efficiency and imposing costs on greenhouse gas emitters. "The strength of solar is the incredible variety and flexibility of applications, from small scale to big scale".

Question: According to a report in 2011, by what year could solar energy provide a third of the world's energy? Question: What could the sun's energy do to help limit climate change?
The territory that now constitutes Tajikistan was previously home to several ancient cultures, including the city of Sarazm of the Neolithic and the Bronze Age, and was later home to kingdoms ruled by people of different faiths and cultures, including the Oxus civilization, Andronovo culture, Buddhism, Nestorian Christianity, Zoroastrianism, and Manichaeism. The area has been ruled by numerous empires and dynasties, including the Achaemenid Empire, Sassanian Empire, Hephthalite Empire, Samanid Empire, Mongol Empire, Timurid dynasty, and the Russian Empire. As a result of the breakup of the Soviet Union, Tajikistan became an independent nation in 1991. A civil war was fought almost immediately after independence, lasting from 1992 to 1997. Since the end of the war, newly established political stability and foreign aid have allowed the country's economy to grow.

Tajiks began to be conscripted into the Soviet Army in 1939 and during World War II around 260,000 Tajik citizens fought against Germany, Finland and Japan. Between 60,000(4%) and 120,000(8%) of Tajikistan's 1,530,000 citizens were killed during World War II. Following the war and Stalin's reign attempts were made to further expand the agriculture and industry of Tajikistan. During 1957–58 Nikita Khrushchev's Virgin Lands Campaign focused attention on Tajikistan, where living conditions, education and industry lagged behind the other Soviet Republics. In the 1980s, Tajikistan had the lowest household saving rate in the USSR, the lowest percentage of households in the two top per capita income groups, and the lowest rate of university graduates per 1000 people. By the late 1980s Tajik nationalists were calling for increased rights. Real disturbances did not occur within the republic until 1990. The following year, the Soviet Union collapsed, and Tajikistan declared its independence.

The nation almost immediately fell into civil war that involved various factions fighting one another; these factions were often distinguished by clan loyalties. More than 500,000 residents fled during this time because of persecution, increased poverty and better economic opportunities in the West or in other former Soviet republics. Emomali Rahmon came to power in 1992, defeating former prime minister Abdumalik Abdullajanov in a November presidential election with 58% of the vote. The elections took place shortly after the end of the war, and Tajikistan was in a state of complete devastation. The estimated dead numbered over 100,000. Around 1.2 million people were refugees inside and outside of the country. In 1997, a ceasefire was reached between Rahmon and opposition parties under the guidance of Gerd D. Merrem, Special Representative to the Secretary General, a result widely praised as a successful United Nations peace keeping initiative. The ceasefire guaranteed 30% of ministerial positions would go to the opposition. Elections were held in 1999, though they were criticized by opposition parties and foreign observers as unfair and Rahmon was re-elected with 98% of the vote. Elections in 2006 were again won by Rahmon (with 79% of the vote) and he began his third term in office. Several opposition parties boycotted the 2006 election and the Organization for Security and Cooperation in Europe (OSCE) criticized it, although observers from the Commonwealth of Independent States claimed the elections were legal and transparent. Rahmon's administration came under further criticism from the OSCE in October 2010 for its censorship and repression of the media. The OSCE claimed that the Tajik Government censored Tajik and foreign websites and instituted tax inspections on independent printing houses that led to the cessation of printing activities for a number of independent newspapers.

Russian border troops were stationed along the Tajik–Afghan border until summer 2005. Since the September 11, 2001 attacks, French troops have been stationed at the Dushanbe Airport in support of air operations of NATO's International Security Assistance Force in Afghanistan. United States Army and Marine Corps personnel periodically visit Tajikistan to conduct joint training missions of up to several weeks duration. The Government of India rebuilt the Ayni Air Base, a military airport located 15 km southwest of Dushanbe, at a cost of $70 million, completing the repairs in September 2010. It is now the main base of the Tajikistan air force. There have been talks with Russia concerning use of the Ayni facility, and Russia continues to maintain a large base on the outskirts of Dushanbe.

In 2010, there were concerns among Tajik officials that Islamic militarism in the east of the country was on the rise following the escape of 25 militants from a Tajik prison in August, an ambush that killed 28 Tajik soldiers in the Rasht Valley in September, and another ambush in the valley in October that killed 30 soldiers, followed by fighting outside Gharm that left 3 militants dead. To date the country's Interior Ministry asserts that the central government maintains full control over the country's east, and the military operation in the Rasht Valley was concluded in November 2010. However, fighting erupted again in July 2012. In 2015 Russia will send more troops to Tajikistan, as confirmed by a report of STRATFOR (magazine online)

Tajikistan is officially a republic, and holds elections for the presidency and parliament, operating under a presidential system. It is, however, a dominant-party system, where the People's Democratic Party of Tajikistan routinely has a vast majority in Parliament. Emomalii Rahmon has held the office of President of Tajikistan continually since November 1994. The Prime Minister is Kokhir Rasulzoda, the First Deputy Prime Minister is Matlubkhon Davlatov and the two Deputy Prime Ministers are Murodali Alimardon and Ruqiya Qurbanova.

Freedom of the press is ostensibly officially guaranteed by the government, but independent press outlets remain restricted, as does a substantial amount of web content. According to the Institute for War & Peace Reporting, access is blocked to local and foreign websites including avesta.tj, Tjknews.com, ferghana.ru, centrasia.ru and journalists are often obstructed from reporting on controversial events. In practice, no public criticism of the regime is tolerated and all direct protest is severely suppressed and does not receive coverage in the local media.

Question: Even though Tajikistan has freedom of the press, what is the problem with it? Question: What access is blocked? Question: What is not tolerated by the government in respect to media? Question: What is not covered by local media?
Tajikistan is landlocked, and is the smallest nation in Central Asia by area. It lies mostly between latitudes 36° and 41° N (a small area is north of 41°), and longitudes 67° and 75° E (a small area is east of 75°). It is covered by mountains of the Pamir range, and more than fifty percent of the country is over 3,000 meters (9,800 ft) above sea level. The only major areas of lower land are in the north (part of the Fergana Valley), and in the southern Kofarnihon and Vakhsh river valleys, which form the Amu Darya. Dushanbe is located on the southern slopes above the Kofarnihon valley.

Tajikistan means the "Land of the Tajiks". The suffix "-stan" (Persian: ـستان‎‎ -stān) is Persian for "place of" or "country" and Tajik is, most likely, the name of a pre-Islamic (before the seventh century A.D.) tribe. According to the Library of Congress's 1997 Country Study of Tajikistan, it is difficult to definitively state the origins of the word "Tajik" because the term is "embroiled in twentieth-century political disputes about whether Turkic or Iranian peoples were the original inhabitants of Central Asia."
