When a gas is heated, it expands, and as it does, it releases more heat, so it releases a lot more.
Petrol, the world’s second-largest petroleum product, is one of the world´s most-produced fuels.
It is also a source of global warming.
In fact, petroleum emissions account for more than a quarter of global greenhouse gas emissions.
According to the United Nations, the use of petroleum in the energy sector can cause global warming by up to 20 per cent.
Petrol is one reason why the oil and gas industry in Saudi Arabia has been in a crisis since the fall of the kingdom´s crown prince last year.
Saudi Arabia’s oil minister was arrested for allegedly violating the countrys laws against corruption.
Saudi King Salman has vowed to crack down on the abuse of power and corruption.
In the last two years, the country has seen more than 1,300 corruption cases and 1,500 arrests for various crimes.
The crown prince is accused of using his position to enrich himself and his family.
Saudi authorities have also been facing a series of corruption cases since the beginning of the year.
The kingdom has a vast network of gas, oil and petrochemicals industries.
In its own words, Saudi Arabia is a nation of entrepreneurs.
But the country´s current economic crisis is not limited to just its energy sector.
One of the most important challenges facing the kingdom is its large amount of waste and water.
Saudi Aramco, the state oil company, estimates that the country wastes around 8.5 million cubic metres of water each day, which amounts to around a quarter the amount of water used in the entire United States.
This means that the vast majority of the country’s water resources is not used.
Another challenge facing the Kingdom is the shortage of affordable housing.
According the World Bank, Saudi citizens live on about $30 a month less than the global average.
“In the current climate, the Saudi economy has already had to deal with the challenges that face the world in the 21st century,” said Javid Adra, an analyst at the International Crisis Group.
“But the kingdom still has a long way to go.”
