Gas prices are on the rise in the United States, and they could make things even worse.
But it turns out the price of oil is far more important than the price that gas is costing, according to an international study published this week in the Proceedings of the National Academy of Sciences.
The research suggests that a gallon or two of gas is worth less than $3 in today’s dollars.
The study looked at the prices of three fuels — natural gas, propane and coal — to see how much they have risen and fallen in the last decade.
In 2005, propylene was $5.40 per gallon, natural gas was $4.40 and coal was $3.60 per gallon.
Now it’s more than $6 per gallon for coal and natural gas.
And for gas, it’s up almost $3 a gallon in the past decade.
The reason for the surge in gas prices is that the U.S. Energy Information Administration, a federal agency, has updated its price of natural gas from $.98 per million BTU in 2005 to $.96 in 2017.
The increase in price is a result of government regulations that require natural gas to have an average fuel price of $.09 per million Btu in 2017, up from $0.85 in 2005.
But those regulations didn’t apply to propylene, natural gaseous and coal.
The rise in gas price reflects the cost of drilling for oil and gas and also the fact that the cost has increased dramatically over the past five years.
The oil price has fallen from about $110 per barrel in 2015 to about $60 per barrel today, according the Oil Price Information Service, which compiles price data for a wide variety of oil and natural resources.
The same process is also happening for natural gas prices, which are now falling and natural gases like propylene and natural gasoline are up about $2 per gallon in recent years.
It’s not just propane, which has seen its prices go up as well, but natural gas as well.
That’s because natural gas is also cheaper than oil, with the price now dropping about $1 per million cubic feet per day, or roughly the cost to burn natural gas in a traditional oil rig.
The price for natural gasses is falling for both propylene as well as natural gas because of regulations on greenhouse gas emissions and the economic recession, according with the International Energy Agency, an independent research group.
“Gas prices are a result not only of government regulation, but also the economic downturn that has been a big factor in natural gas price growth over the last 10 years,” said Mark Zandi, chief economist at Moody’s Analytics.
“There are two things that make propylene cheaper than natural gas: the price drops with time and it has a lower cost of production.”
The study did find that natural gas used to be cheaper than coal.
“But we think that propylene is the natural gas for the future,” Zandi said.
“In fact, we think propylene will be a very important future fuel.”
The price of coal is rising, too.
Zandi says the cost is dropping.
But he cautions that it’s still unclear whether the price increase is because of coal’s decline or whether natural gas or propylene have caused it.
“It’s really a case of price change versus the impact of government actions, or a combination of both,” he said.
Gas prices may not be the only thing to watch in the coming years.
In April, the U,S.
Department of Energy and the Environmental Protection Agency released new regulations on carbon emissions that will put new restrictions on coal plants and coal ash dumps.
The rules could make the process of cleaning up coal a lot more difficult and expensive for local communities.
And in June, President Donald Trump signed a sweeping executive order that banned the federal government from funding coal mines, power plants and other infrastructure projects.
