Renewable energy means using the power of the sun, or the wind, or the movement of water in rivers and oceans to generate power. Once these power plants are established there are no emissions of carbon dioxide or any other pollutants. Non-renewable energy (from burning coal, oil and natural gas, mostly) releases vast amounts of carbon dioxide into the atmosphere increasing our greenhouse gases and contributing to global warming and climate change. So renewable energy is much better for society than non-renewable energy.
It would be naïve to say that there is a completely renewable source of energy. The sun, for example, which is the source of all energy on Earth, will form a Red Giant in a few billion years time, and will produce far less energy than it had in the past. Additionally, although wind (which relies on the sun) is renewable per say, machines to make use of wind energy, such as wind turbines, require maintenance et cetera and are in that sense, not *completely* renewable. However, for our purposes, and especially in contrast to Fossil fuels, the Sun, the wind, the tides et cetera are renewable sources of energy. Windmills are machines which convert the wind's energy into another form of energy. They, themselves, are not "renewable *sources," rather they can make use of a 'renewable' source, 'the wind,' to transform kinetic into potential energy.
Worse in what respect? Renewable energy is generally much better environmentally, but usually costs more than non-renewable. Non-renewable energy from coal, oil, and natural gas causes both air and water pollution, and greenhouse gases. Renewable energy from windmills interferes with the habitat and migration of birds and bats, hydro power diverts spawning patterns and can lead to flooding, nuclear generates dangerous waste, biomass can likewise release toxic substances, geothermal is efficient but extraordinarily costly. That pretty much leaves solar, which still has a long way to go in regard to efficiency, but progress is being made there. The decision which is better ultimately depends upon your needs, your resources, your location, and your environmental awareness.
The reason that wind energy is better than oil or gas is because it is a renewable resource. While there is a limited amount of oil on this planet, there is an unlimited supply of wind. In addition, the damage to the environment is much smaller with wind power, due to the fact that there are no emissions from, say, burning materials.
Renewable sources of energy are better than nonrenewable sources because they are sustainable and do not deplete finite resources. They also have lower environmental impact, such as reduced greenhouse gas emissions and air pollution. Additionally, renewable energy sources can help increase energy security and create jobs in the clean energy sector.
Fossil fuels are non-renewable so have a finite supply. This means that they will eventually run out. They also produce carbon dioxide when burnt which contributes towards global warming. Renewable sources do not pollute the atmosphere and do not run out. Therefore renewable sources are better for the environment, but fossil fuels give more energy per mass. Which is better depends on what you look for, environment and sustainability or high density of energy. Renewable energy still gives out sufficient energy, so renewable sources are better.

Because renewable sources can be replenished (apex) because we will not run out of them
Because renewable sources can be replenished (apex) because we will not run out of them
They are called renewables. (though strictly, nuclear power is not a fossil fuel and is not renewable).They are called alternative energy sources.
Renewable energy resources.
A renewable source of energy (sunlight, wind or water power, etc) is an better option to generate electricity because it is a natural source of energy and renews itself again and again. It also releases no carbon dioxide pollution into the greenhouse gases in the atmosphere.A:Renewable energy sources are much better in the long run. Renewable energy sources never run out. We can constantly use renewable energy sources however non-renewable energy sources will run out eventually with consistent consumption. A great example of a renewable energy sources is solar power. We will never run out of energy from the sun. A:They are important because they can be replenished and they do not harm our environment and they are eco-friendly
Wind energy is considered better than other energy sources for several reasons. It is a renewable and clean energy source that does not produce greenhouse gas emissions or air pollutants. Additionally, wind energy provides an abundant and consistent source of power, reducing dependence on fossil fuels and contributing to energy diversification.
because it is more efficiant than any other form of energy
Geothermal energy is considered better than other energy sources because it is renewable, sustainable, and produces low levels of greenhouse gas emissions. Additionally, geothermal power plants have a small land footprint and can operate continuously, providing a stable source of electricity.
