Renewable energy is energy that comes from natural resource. Such as- wind, rain, sunlight, tide, etc.
Sunligth(Daylighting) is best Resources of natural energy.
"Daylighting, A new paradigm in use of solar energy" pioneered in India by skyshade.
Stop use electricity for 9 -10 hrs/day with skyshade products.
9 years - More than 20,000 Installations - Saving 40million Kwhrs - Reducing
34,000MT of CO2reduction per year.

Sun mixed with the wind is the best of the three. Geothermal is a great way to go but Joe Public don't have a backhoe in their backyard that they can use to dig the trenches required for geo. Solar and the wind on the other hand can be shipped in a box and about anyone can open a box and tie a wire on a solar module and to a battery. The Wind is a little harder because it requires two or more people to install and a larger amount of land because of the guy wires, makes noise etc.
1. Solar
2. Wind
3. Geo.

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.

If gasoline is the same price in my town as diesel and biodiesel (it's always the same price) what fuel is the best for me? buying a new car?

Energy density says with diesel at 35.8 megajoules per liter and gasoline at 34.2, you should go a bit further with diesel.
Energy density Wikipedia
Diesel, esp. from petro sources, tends to create more hydrocarbon pollutants and particulates per distance traveled, esp on short hops where the engine doesn't warm up to it's higher efficiency range. Diesels like running on long trips.

Diesel engines tend to be noisier. Diesel could have issues with fuel gelling in very cold weather if it has insufficient winter additives, and sometimes even that isn't enough for a frigid weather startup..

Gasoline is more refined than diesel and likely has a bigger production environmental footprint than diesel, although diesel has a bigger combustion environmental footprint. Biodiesel can be better depending on its source.

Usually you do not have the choice of diesel vs. gasoline for the same model of car, so there will be other factors to consider besides fuel type. Best wishes shopping for your next vehicle.

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.

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.

What sources of power do you think will be used in the future?

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.

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.

I have a problem related to a solar system and I don ' tknow where to go with it

Hello -

It may depend upon where you reside. In some locations, electric power companies have boosted their rates for those with solar power panels.

This web page may prove informative:

Without knowing where in the world you reside, it is difficult to provide you with specific information.
