Usually an "alternative energy source" is one that is not now a major contributor to our energy supplies. That would make "alternative energy" anything that is not based on fossil fuels of one sort or another. Some people exclude nuclear energy from the "alternative" universe
The department that would typically oversee the use of alternative energy sources for vehicles is the Department of Energy. They are responsible for promoting energy efficiency and advancing renewable energy technologies in the United States.
It depends which country you are referring to
An alternative resource, just as the term implies is a source of something which is different from the most common source. For example the most common source of automotive fuel is fossil fuels pumped from the ground, however it is possible to make automotive fuel from corn oil or from sugar. These would be alternative resources. These will help people in the future!
Nuclear energy is the alternative energy source that is least dependent upon the weather. Unlike solar or wind power, nuclear power generation is not affected by weather conditions such as sunlight or wind.
Geothermal, because it is one of the easiest to use and install.
That would be wind! Wind is a renewable energy source (it can generate electricity). Wind also has its origins in solar energy.
Electricity generated from renewable sources (solar, wind, water etc) would be an alternative energy source and would easily cover cooking and heating. It would protect the environment by reducing the amount of fossil fuel burnt, and also because it has no dangerous carbon dioxide emissions that are causing global warming.
Any alternative energy source can help achieve this. The question is whether you can find a practical way to use such energy.
Solar energy would be the most useful alternative energy source for my location due to ample sunlight throughout the year. This would help reduce dependency on traditional fossil fuels and lower carbon emissions in my community. Additionally, solar energy is becoming more cost-effective and scalable, making it a practical choice for residential and commercial use.
I would. Alternative energy would cost more in the short term, but in the long term, it evens out.
Not sure what your asking, but alternative energy sources would be hydroelectricity, solar energy, bio fuels, wind, and geothermal.
