Fossil fuels.
Yes they are, because they use non polluting wind power and provide energy that might otherwise require polluting sources of energy, such as coal, oil, or gas. The wind does not always blow enough to turn the blades, but, it does move enough to produce energy most of the time. Wind turbines do not pollute the wind, and they do minor damage to birds and bats. Nothing is perfect, and wind power is the energy that Probably does the least amount of damage to the environment, while providing an excellent source of energy most of the time.
Sources do not contribute to needs, they contribute to SUPPLY.Needs are generated by people and industry.
Currently, the world is heavily dependent on fossil fuel. But we might soon run out of it, and the amount of pollution it is creating is also alarming. The future of energy sources lie in the non-conventional sources of energy, most importantly solar, wind and tidal energy. Also alternative forms of energy like Hydrogen and BioAlcohol based fuels are close short term alternatives to reduce the dependency on fossil fuel. They produce little or no carbon di oxide, and are cheaper to generate too.
By using alternative resurces (most of which are natural and reuseable), people can conserve the energy that comes from finite resources. This helps to preserve those resources and also reduce the heavy waste that usually comes with them.
The world is primarily dependent on fossil fuels, such as oil, coal, and natural gas, for most of its energy needs. These resources account for a significant portion of global energy consumption, powering transportation, electricity generation, and industrial processes. This reliance poses challenges, including environmental degradation, climate change, and geopolitical tensions. Transitioning to renewable energy sources is crucial for creating a more sustainable and resilient energy future.
Fossil fuels, such as coal, oil, and natural gas, are considered the most damaging sources of energy to the environment. When these fuels are burned, they release harmful greenhouse gases and air pollutants, leading to air and water pollution, climate change, and other environmental impacts.
The mining and burning of coal is the most damaging to the environment.
Renewable energy sources such as solar and wind power are the most beneficial for the environment because they produce little to no greenhouse gas emissions during energy generation. They also have low environmental impact compared to fossil fuels in terms of air and water pollution, land disturbance, and wildlife disruption.
solar energy and win energy are the most environment friendly because the are renewable source of energy.moreover they are present in abundance.whereas water is also a renewable source but it is more difficult to renew it.hence solar and wind energy are the best option.
Examples of non-conventional energy sources, that have the most practical use, are tidal, geothermal, solar, wind and biomass energy.The main three advantages of these non-conventional energy sources are:decreasing dependence on fossil fuel resources.saving environment from pollution.not contributing to global warming.
The most common alternate energy sources (as alternates to to fossil energy sources, oil, gas, and coal) are : nuclear energy, wind energy, and solar energy.

The energy sources that I am most excited about all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, and Hydroelectric Energy sources.
Radiant energy is the safest energy for people and the environment.
The concept of integrated, sustainable energy management recognizes that we cannot depend on a single energy source, but that, instead, we need to use a mixture of energy sources. These energy sources have to be reliable, less damaging to the environment, and most importantly, sustainable. So, instead of moving only towards "clean coal technology" or "100% nuclear power," we need to incorporate other alternative energy types. Within IEM, there is also this idea of "micropower." Micropower is a concept that suggests we should move away from large-scale power plants, to more local distribution power systems.
solar power
Yes, the majority of our energy sources, including fossil fuels, wind, hydroelectric, and solar power, ultimately originate from the Sun's energy. The Sun's energy drives processes like photosynthesis and weather patterns, which in turn creates these energy sources on Earth.
