The Impact

In regions where natural gas is used for both power generation and heating buildings, extreme cold weather events can place the electrical system under enormous stress and challenge the ability to meet residential heating and electric demands. Residential demand response has long been used in the power sector to curtail summer electric load, but these types of programs in general have not seen adoption in the natural gas sector during winter months. Natural gas demand response (NG-DR) has garnered interest given recent extreme cold weather events in the United States; however, the magnitude of savings and potential impacts—to occupants and energy markets—are not well understood. We present a case-study analysis of the technical potential for residential natural gas demand response in the northeast United States that utilizes diverse whole-building energy simulations and high-performance computing. Our results show that NG-DR applied to residential heating systems during extreme cold-weather conditions could reduce natural gas demand by 1–29% based on conservative and aggressive strategies, respectively. This indicates a potential to improve the resilience of gas and electric systems during stressful events, which we examine by estimating the impact on energy costs and electricity generation from natural gas. We also explore relationships between hourly indoor temperatures, demand response, and building envelope efficiency.

Gas consumption exist great regional difference, price and income are the main factors affecting consumption .Global gas consumption has slow growth, but the price in 2008 there was a twist. We analyze the global natural gas consumption and price points using the data from the BP. The level of economic development and natural gas reserves determine the differences in the levels of consumption. In order to eliminate the impact per unit, the regression model uses the data in the log. This paper studied the influence factors of natural gas consumption in North America using of consumer income elasticity and price elasticity. The results show that the gas consumption have a low income elasticity and price elasticity is higher .Law of "S" shape can explain the income elasticity is low, the reason is that the stage of economic development. Price elasticity is higher lies in the different between Canada and the United States, the United States is a net importer of natural gas, and Canada is a net exporter.

Abstract Major League Baseball is played from the beginning of April through the end of October each year, encompassing three of the four meteorological seasons: spring, summer, and fall. The 30 teams play in cities across the United States and Canada in many types of weather. This work studies the impact of temperature on a Major League Baseball game by examining the association between temperature and several Major League Baseball game statistics, including runs scored, batting average, slugging percentage, on-base percentage, home runs, walks, strikeouts, hit-batsmen, stolen bases, and errors. Data from 22 215 games, spanning the 2000–11 regular seasons, were studied. Temperature was categorized as “cold,” “average,” and “warm.” Analyses were performed on the following populations: all Major League Baseball games, games played in the National League, games played in the American League, and games played in 23 different stadiums that are currently being used by Major League Baseball teams. Home and away teams' performances were analyzed separately for each population of games. The results of this study show that runs scored, batting average, slugging percentage, on-base percentage, and home runs significantly increase while walks significantly decrease in warm weather compared to cold weather.

Subject Nicosia’s decision to revoke the citizenship of 26 foreign nationals. Significance Cyprus has tightened up its Citizenship by Investment Programme (CIP) with regard to certain controversial individuals out of a desire to strengthen relations with the United States and EU. This is particularly important given Turkish efforts to prevent Cyprus exploring for natural gas in its waters. Impacts According to a finance ministry study, CIP made a positive but relatively small contribution to GDP during 2013-18. The construction sector benefited in particular, with employment rising by about 8%. The effect on property prices seems largely to have been confined to Limassol. The impact on Cypriot banking amounted largely to stabilising the sector and providing a new source of finance during the banking crisis.

Natural Gas Demand

<p>UK natural gas demand is 2-4 times that of electricity and characterised by seasonal differences in demand of almost triple in the winter with larger spikes during extreme cold weather events. This makes any decarbonisation effort reliant on its ability to handle these large changes in demand. Conversion of the gas supply to hydrogen is the most promising solution. To facilitate this, large-scale underground storage will be required in the order of 150 TWh or 40 days’ worth of supply.</p><p>Subsurface gas storage in porous rocks requires a proportion of the gas to remain in the reservoir to maintain the pressure required for the minimum economic flow rate from the wells. This is called the cushion gas requirement. In the case of a hydrogen storage reservoir the use of a cheaper cushion gas, such as CO<sub>2</sub> or N<sub>2</sub>, is the subject of much research.</p><p>We investigate the possibility of using natural gas within a partially depleted gas reservoir as cushion gas. We will present the results of a compositional simulation of seasonal hydrogen storage over a 20 year period in a closed reservoir. The study shows that natural gas has potential as a cushion gas, in this case achieving greater than 95% hydrogen recovery factors with minimal amounts of mixing in the reservoir. Use of natural gas as cushion gas also reduces the risk of water coning which can lead to loss of hydrogen.</p><p>Although these results are promising, the study highlights several key areas that need further investigation to improve the reliability of future simulations. These include defining relative permeability curves for hydrogen, refinement of how simulators handle viscosity equations, and a greater understanding of hydrogen well engineering. All of these factors will influence estimates of the hydrogen capacity of a porous rock reservoir.</p>

Subject Prospects for natural gas in the fourth quarter. Significance Platts report that US average spot monthly natural gas price for September fell to 2.35 dollars per million British thermal units (mmbtu), comparing with prices of around 4.0 dollars/mmbtu a year ago. Outside the United States prices are higher, but the trend of softening prices and a relatively weak demand response is the same. China's demand is growing, but not enough to outdo the global supply of liquefied natural gas (LNG) into the fourth quarter.

Energy Type

Natural gas, which is primarily methane, is used in the electric power industry, various industrial applications, residential heating, and, to a small extent, as a transportation fuel. In terms of electricity generation for the United States, natural gas is responsible for about 35%, a large growth from only 15% twenty years earlier. In 2015 natural gas overtook coal and is now the primary energy for producing electricity. It is a relatively clean burning energy type and, compared to coal and petroleum crude oil, it contains small amounts of sulfur and nitrogen and no heavy metals such as selenium, mercury, and cadmium. To support the use of natural gas to generate electricity, the United States has about 1,800 plants with close to 6,000 generators and 1.6 million miles of pipelines.
