In February 2017, the price of a gallon of gas on the New York Mercantile Exchange (NYSE) rose by more than $1 to $1.68 a gallon.
By November, the prices had gone up by more then $5.
In March 2018, the cost of a barrel of natural gas rose by $1 a barrel.
By June 2019, gas cost $1 less than it did the previous month.
But when the US oil price crashed in June, natural gas prices skyrocketed.
It’s a dramatic rise that happened before the OPEC deal was reached and before prices fell in other countries.
It happened before oil prices went up by $50 a barrel in September 2018, which is when US prices started to fall.
It took time for US natural gas to fall below $1, but it happened.
US oil prices have fallen by $100 a barrel a month, but the price rise for gas is $1 per barrel.
The price of gas is not the only thing that has been rising.
The amount of electricity generated in the US has also been increasing.
The electric grid has been expanding and people are getting more efficient, which in turn has increased the amount of energy people can use in their homes.
In some ways, natural and nuclear power are also making the US more energy efficient.
But US energy production is still falling, which means that people will be paying more for energy.
So when you think about the energy costs, you need to think about that and energy efficiency, too.
