In my opinion, the use of fossil fuel sources of energy will decrease in the near future. Meanwhile, other forms of clean energy will be cheaper and more available, like: solar, wind and hydroelectric energy.

### Can hydrogen run a generator to produce hydrogen perpetually?

No. We all can't be versed on every aspect of our world but some parts are important to keep us from falling into poor investments and scams. There are several laws of thermodynamics, essentially how energy works in our world and are a fundamental part of our understanding of physics.

One of those laws suggests that energy like arithmetic will not change unless something operates to change the numbers. The energy that is put into a system (2 + 2) is always going to equal the energy that goes out of a system (4) So just as 2 + 2 is not going to suddenly equal 5 or 6 the energy we put into our system is not somehow going to create more energy. The best we can hope for is to create a system that will somehow gather more energy from another source like solar panels. In this case it is like saying 2 + 2 + 1 equals something more.

In your suggestion you want to add hydrogen to a generator and then use the resulting electricity to produce hydrogen by splitting water and then use that hydrogen to run the engine. But you are leaving out some of the elements. The engine is probably no more than about 25% efficient. That means that 75% of the energy in the hydrogen fuel you use is used to create heat and is lost to friction. So far your equation then looks like 2 + 2 - 3 . The generator also loses some energy to friction. Add to this it takes more energy to split water into hydrogen and oxygen than we recover when hydrogen and oxygen combine to produce some excess energy. So in every step along the way we are losing our desired goal to losses in energy like heat and friction.

But even if the system were somehow perfect it could not be any more perfect than to lose no energy. You will not be creating new new energy with such a system. Even if we could get it to run forever the system is not going to give us new energy we could use for something else as every bit would be used to run the system. This is why we say that efficiency can never be greater than 1 or 100%. And we can not have "over unity" or "perpetual motion" machines.

If we want "free energy" what we could do is make solar panels. And then use those solar panels to gather additional energy from a source outside the system and then produce hydrogen from solar energy. What we can't do is use a solar panel to produce electricity for a light that shines on the solar panel as once again this would be a closed system with no energy flowing into the system.

When it comes to energy systems look for the source of the energy. If it is supposed to be coming from inside the system perpetually then it is likely a scam. If there is an outside source it may be useful depending upon the economics and how much energy we get relative to our energy investment.

### Fuel Question , What Fuel is the cheapest and gives the Highest Mileage per Litre in Engines ?

Steam or electric are probably cheapest TO RUN... But most expensive to buy.... Butane would probably be next... It is actually a Mixture of Butane, Methane and a few others... In Australia it is the same as we use for the BBQ..... This would probably be next.... but unless the car is Factory converted,... then you will probably need some Petrol/Gasoline just to start .. You use maybe 2 or 3 Cupfuls each time so you don't use Much... It is also a Good backup if you run out of LPG....... The rest... it depends on th e Government and Fuel Companies which one is cheapest but what it SHOULD be id From cheapest up... Diesel, Unleaded, Premium Unleaded
Forget the rest... They would be cheap to run but the conversion would be so expensive it would be not worth the effort

### Why is coal a nonrenewable energy source, but biomass, such as wood, considered a renewable energy source?

coal is a fossil energy source, like oil and gas - all these are considered nonrenewable - well it does takes a couple of million years to form these whereas a tree grows within a couple of years.

### What will be our next major source of energy?

The sun and the wind will both be our major source of energy in the future. The sun is always there and the turbines will be needed to supply energy to homes in the winter time. we will see only electric cars on the roads and the airline industry will have to figure out something cause planes do not fly on solar power.

### Will my 18watt solar panel charge a car battery and how fast?

If you hook it up correctly and the Voltages match... yes.

As for how long... THAT depends on a number of Factors... How much sun, What quality is the Solar Panel, Placement of the Panel.. the goes on and on... But you CAN charge a Battery...I charged a Battery for quite some time using a Large Solar array.... We were Camping an using the Battery for Lights Radio and Fridges.... So it CAN be done

### Do appliances consume energy when they're plugged in but turned off?

Electric toaster is an electric device without electronics. But some toasters are now available with digital circuits. But those circuits will not consume current more than 1watt. There is also a fact that an electric circuit can draw current by induction. But the effect is very very low here. Therefore it is not going to be big problem in your electricity bill even if forget to unplug.

### How do non conventional energy better than fossil fuels?

Mankind has developed a way to utilize the sun's vast energy by converting its sunlight into electricity via photovoltaics and other solar power methods. The fossil fuels in the form of plants underneath the earth which transform into oil over time are drilled using polluting machinery.

### Why do we need renewable energy?

This helps to reduce climate change. By using renewable energy sources like solar energy, we also reduce our dependence on fossil fuel gas and oil reserves, which are becoming more expensive and difficult to find. It also reduces our dependence on imported fossil fuels, improving our energy security.
