The new energy sources that are popping up are creating a new energy boom for cities, which need more of the clean, green, cheap energy that comes from solar panels and wind turbines.
But some energy experts say that the technology behind these new fuels is not as clean as they might have you believe.
So we’ve created this list of 10 fuel types you should know about.1.
Green gasFuel, like hydrogen, can be created by taking hydrogen out of an oil or gas source and mixing it with water and oxygen.
That creates a gas called gaseous hydrogen, which is a clean fuel.
Green hydrogen is a much better alternative than natural gas because it’s more energy-efficient than the fuel you’re going to get in your car.
The problem is, the technology for making gaseus is very expensive, which means you need lots of energy to create it.2.
Oxidized hydrocarbonsOxidized hydrogen is also a gas.
It’s a more efficient fuel than natural gaseuses because it has a low boiling point.
The boiling point of hydrogen is 2.5 degrees Celsius, compared with about 20 degrees for natural gases.3.
Lithium fuelA lithium-based fuel is similar to natural gas but has a higher boiling point, about 20, and a higher efficiency.
This makes it much better than natural hydrogen because it burns cleaner than natural fuel.
This is because lithium makes up only about 2 percent of the atmosphere.
But the amount of lithium produced each year is still a lot, since the lithium atoms can make up only one percent of an electrolyte.4.
Liquid hydrogenA liquid hydrogen, also known as liquid fuel, is made from liquid hydrocarials.
These are water, carbon dioxide, oxygen and other substances.
The liquid hydrogen is about 20 percent hydrogen, compared to about 20 to 25 percent for natural gas.5.
BiofuelsThere are several biofuels.
Most are made by adding hydrogen, methane, nitrous oxide and carbon monoxide to natural fuels.
Some biofures are better than others.
But all biofuils are more expensive than natural fuels and are more likely to contain toxic pollutants like benzene and to emit CO2, which can damage the lungs.6.
EthanolAn ethanol-based biofuel is made by mixing ethane with water to create ethanol.
It contains more than 80 percent ethanol.7.
NaphthaThe petroleum-based Naphthas is an alternative to natural hydrocarines.
It has about 60 percent ethanol and only a small amount of natural gas, compared the natural gas that comes out of your car when you’re filling up.8.
Wind turbinesOne of the best ways to make wind energy is to use wind turbines to produce electricity.
They can be located on a hill or at an elevation, so you can make the wind farm much bigger and use it for generating power for your home, business or office.
A wind turbine can also be placed on top of a power line to generate power to your house.
You can use the power of the wind to make electricity.
The wind turbines can produce up to 1,000 megawatts (MW), or enough to power nearly half of all the homes in the U.S. The U. S. Department of Energy estimates that by 2050, there will be up to 20,000 wind turbines in the country, or about 20 times more than are currently in operation.9.
Solar cells and solar panelsThe newest technology to become more widely available is solar cells.
These batteries store energy and can be used for energy storage or as power sources.
The batteries are made from solar cells, but they also use other materials like silicon and silicon dioxide, which are more cost-effective.10.
Natural gasThe natural gas used to make the fuel listed above comes from natural gas and is often made from shale gas.
But it’s not always easy to find natural gas in large quantities.
Natural oil is typically refined and then blended with other ingredients to create natural gas like ethane and propane.
Natural gas is a very clean fuel because it doesn’t contain carbon dioxide.
But if you want to make sure that your car doesn’t get dirty and pollute the air, you’ll want to keep your car running at a safe level.
