their normal use. Comparative cost of production In their May 2019 comparison of the "cost of supply curve update" in which the Norway-based Rystad Energy—an "independent energy research and consultancy"—ranked the "worlds total recoverable liquid resources by their breakeven price", they listed the "Middle East onshore market" as the "cheapest source of new oil volumes globally" with the "North American tight oil"—which includes onshore shale oil in the United States—in second place. The breakeven price for North American shale oil was US$68 a barrel in 2015, making it one of the most expensive to produce. By 2019, the "average Brent breakeven price for tight oil was about US$46 per barrel. The breakeven price of oil from Saudi Arabia and other Middle Eastern countries was US$42, in comparison. Rystad reported that the average breakeven price for oil from the oil sands was US$83 in 2019, making it the most expensive to produce, compared to all other "significant oil producing regions" in the world. The International Energy Agency made similar comparisons. In 2016, the Wall Street Journal reported that the United Kingdom, Brazil, Nigeria, Venezuela, and Canada had the costliest production. Saudi Arabia, Iran, and Iraq had the cheapest. Future projections Peak oil is the period when the maximum rate of global petroleum extraction is reached, after which the rate of production enters terminal decline. It relates to a long-term decline in the available supply of petroleum. This, combined with increasing demand, will significantly increase the worldwide prices of petroleum derived products. Most significant will be the availability and price of liquid fuel for transportation. The US Department of Energy in the Hirsch report indicates that "The problems associated with world oil production peaking will not be temporary, and past "energy crisis" experience will provide relatively little guidance." Global annual crude oil production (including shale oil, oil sands, lease condensate and gas plant condensate but excluding liquid fuels from other sources such as natural gas liquids, biomass and derivatives of coal and natural gas) increased from in 2008 to per day in 2018 with a marginal annual growth rate of 1%. During the year 2020 crude oil consumption is expected to decrease from earlier year due to Coronavirus disease 2019 pandemic. Impact of rising oil price The rising oil prices could negatively impact the world economy. One example of the negative impact on the world economy, is the effect on the supply
