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.

What are the programs that gives credit to households for delivering electricity to the grid called?
Answer: Net metering programs


Problem: The usefulness of the canals was short-lived, though some have now been restored for recreation. The 19th century also saw the construction of railways to and through Somerset. The county was served by five pre-1923 Grouping railway companies: the Great Western Railway (GWR); a branch of the Midland Railway (MR) to Bath Green Park (and another one to Bristol); the Somerset and Dorset Joint Railway, and the London and South Western Railway (L&SWR). The former main lines of the GWR are still in use today, although many of its branch lines were scrapped under the notorious Beeching Axe. The former lines of the Somerset and Dorset Joint Railway closed completely, as has the branch of the Midland Railway to Bath Green Park (and to Bristol St Philips); however, the L&SWR survived as a part of the present West of England Main Line. None of these lines, in Somerset, are electrified. Two branch lines, the West and East Somerset Railways, were rescued and transferred back to private ownership as "heritage" lines. The fifth railway was a short-lived light railway, the Weston, Clevedon and Portishead Light Railway. The West Somerset Mineral Railway carried the iron ore from the Brendon Hills to Watchet.
What was built int the 19th century 
The answer is the following: 19th century also saw the construction of railways to and through Somerset


The first and last Roman known as a living divus was Julius Caesar, who seems to have aspired to divine monarchy; he was murdered soon after. Greek allies had their own traditional cults to rulers as divine benefactors, and offered similar cult to Caesar's successor, Augustus, who accepted with the cautious proviso that expatriate Roman citizens refrain from such worship; it might prove fatal. By the end of his reign, Augustus had appropriated Rome's political apparatus – and most of its religious cults – within his "reformed" and thoroughly integrated system of government. Towards the end of his life, he cautiously allowed cult to his numen. By then the Imperial cult apparatus was fully developed, first in the Eastern Provinces, then in the West. Provincial Cult centres offered the amenities and opportunities of a major Roman town within a local context; bathhouses, shrines and temples to Roman and local deities, amphitheatres and festivals. In the early Imperial period, the promotion of local elites to Imperial priesthood gave them Roman citizenship.
For what was Augustus's reformed system of government notiable?
integrated


Input: Southern Europe
European overseas expansion led to the rise of colonial empires, producing the Columbian Exchange. The combination of resource inflows from the New World and the Industrial Revolution of Great Britain, allowed a new economy based on manufacturing instead of subsistence agriculture.

Aside from the activities of colonies, what other event fostered the transition from agriculture to manufacturing?
Output: the Industrial Revolution of Great Britain


Input: Article: The Aeneid is widely considered Virgil's finest work and one of the most important poems in the history of western literature. Virgil worked on the Aeneid during the last eleven years of his life (29–19 BC), commissioned, according to Propertius, by Augustus. The epic poem consists of 12 books in dactylic hexameter verse which describe the journey of Aeneas, a warrior fleeing the sack of Troy, to Italy, his battle with the Italian prince Turnus, and the foundation of a city from which Rome would emerge. The Aeneid's first six books describe the journey of Aeneas from Troy to Rome. Virgil made use of several models in the composition of his epic; Homer, the preeminent author of classical epic, is everywhere present, but Virgil also makes special use of the Latin poet Ennius and the Hellenistic poet Apollonius of Rhodes among the various other writers to which he alludes. Although the Aeneid casts itself firmly into the epic mode, it often seeks to expand the genre by including elements of other genres such as tragedy and aetiological poetry. Ancient commentators noted that Virgil seems to divide the Aeneid into two sections based on the poetry of Homer; the first six books were viewed as employing the Odyssey as a model while the last six were connected to the Iliad.

Now answer this question: How many books are included in The Aeneid?

Output: 12


Problem: Since the work of Franz Boas and Bronisław Malinowski in the late 19th and early 20th centuries, social anthropology in Great Britain and cultural anthropology in the US have been distinguished from other social sciences by its emphasis on cross-cultural comparisons, long-term in-depth examination of context, and the importance it places on participant-observation or experiential immersion in the area of research. Cultural anthropology in particular has emphasized cultural relativism, holism, and the use of findings to frame cultural critiques. This has been particularly prominent in the United States, from Boas' arguments against 19th-century racial ideology, through Margaret Mead's advocacy for gender equality and sexual liberation, to current criticisms of post-colonial oppression and promotion of multiculturalism. Ethnography is one of its primary research designs as well as the text that is generated from anthropological fieldwork.
When did Bronislaw Malinoswki and Franz Boas do their relevant work?
The answer is the following:
late 19th and early 20th centuries
