Electricity suppliers will offer a contract based on a range of different tariffs, from a single-rate tariff with a single price for each unit of electricity used, through two-rate (different unit rates for day and night) to multi-rate seasonal time of day (STOD) tariffs which could have up to several different unit rates. In Israel there are 9 such rates
The rate base is a group of basic assumptions used to calculate the long-term price of electricity production, conduction and delivery, and serves as the foundation for setting the electricity tariff. This includes a basket of normative costs for each branch of the electricity sector that the electricity tariff is supposed to cover. For example, the cost of the construction of a power station and the cost of fuels (for the generation sector); the cost for the construction of the grid (for the transmission sector) or the cost of setting up a transformation station and services offered to the public (for the distribution sector). The rate base was first set in Israel by the Public Utility Authority-Electricity in 1997 for 5 years and was then updated in 2002. In February 2010, the PUA approved the new tariff structure for the years 2010-2014, which will include a 10% reduction in electricity tariff for households and a 16.3% reduction for industrial users

Oil sand is a porous rock layer often a mixture of sand, clay, water and bitumen. Oil sands most often refer to Canada where over 170 million barrels of bitumen are estimated to be in place. It is a sedimentary rocks containing heavy oil that cannot be extracted by conventional petroleum recovery methods. The extraction of oil from tar sands is the world’s most capital-intensive method for extracting oil and is also one of the most environmentally destructive. Transforming the tar/bitumen, which is mixed with sand into petroleum is energy intensive and creates significant carbon emissions. Steam created by burning natural gas separates the semisolid bitumen. Then more natural gas is needed to turn the bitumen into synthetic crude, which can be processed by refineries. Spent water used in oil sands projects is placed in lake-sized tailings ponds, one of which killed hundreds of migrating birds in Canada in 2008. Seepage from the ponds is polluting rivers. Strip mining of the oil sands, the most common method of extraction, has destroyed large swaths of forest.
