It's difficult to say that any element produces no harmful emissions.
That said, if solar or wind power is used to split water into hydrogen and oxygen, then burning the hydrogen just creates water again, so that would not be harmful.
The term "release energy" refers to the process of converting stored energy into a usable form, such as heat or electricity. When energy is released, it can have both positive and negative impacts on the environment. For example, burning fossil fuels releases energy but also produces harmful emissions that contribute to air pollution and climate change. On the other hand, renewable energy sources like solar and wind power release energy without producing harmful emissions, making them more environmentally friendly options.
For this the proper metric for comparison is the energy density of the fuel. Coal: 6.7 KW-hr per kg Natural Gas: 14.9 KW-hr per kg. So natural gas produces more energy per kg than coal.
Coal and natural gas differ in their environmental impact and energy production efficiency. Coal produces more greenhouse gas emissions and air pollutants compared to natural gas. Natural gas is considered cleaner and releases fewer emissions when burned. In terms of energy production efficiency, natural gas is more efficient than coal as it produces more energy per unit of fuel.
Nuclear energy emits lower greenhouse gas emissions compared to fossil fuels, reducing the impact on climate change. Additionally, nuclear waste can be managed and contained more effectively than the air pollution and CO2 emissions from burning fossil fuels. Overall, nuclear energy has a smaller environmental footprint in terms of air pollution and carbon emissions.
Using uranium as an energy source produces less greenhouse gas emissions compared to burning coal, which helps to combat climate change. Additionally, uranium is a more efficient energy source as it produces more energy per unit of fuel compared to coal. Uranium also has a lower impact on air quality by emitting fewer pollutants during the energy generation process.
It is the cheapest form of energy and produces no carbon emissions.

Geothermal energy is considered a clean and renewable energy source because it produces almost no greenhouse gas emissions or air pollutants during operation. However, there can be some risks of releasing harmful gases, such as hydrogen sulfide, if not managed properly. Advanced technologies and monitoring methods are used to minimize these risks in geothermal power plants.

Reducing emissions means decreasing the amount of harmful pollutants and greenhouse gases released into the atmosphere. This can be achieved by adopting cleaner technologies, improving energy efficiency, promoting renewable energy sources, and implementing policies to limit emissions from industries and transportation.
The main advantage of using solar energy is that it is renewable. The sun produces more energy in a minute than the planet uses in a year, and will take several billion years to run out. The sun also does not pollute. Coal and oil, however, will run out, and the emissions produced by them are very harmful.
It will help conserve precious hydrocarbons and reduce harmful emissions and global warming here on Earth.
Biomass energy is important for sustainable development and reducing carbon emissions because it is a renewable energy source that can be produced from organic materials like plants and waste. By using biomass energy, we can reduce our reliance on fossil fuels, which produce harmful carbon emissions that contribute to climate change. Switching to biomass energy helps to lower carbon emissions and promote a more sustainable energy future.
An advantage of using more nuclear energy is that it produces lower greenhouse gas emissions compared to fossil fuels.
Geothermal energy typically produces low amounts of harmful gases, with the main emissions being carbon dioxide, hydrogen sulfide, and ammonia. These gases can be released during the drilling and operation of geothermal power plants, but their levels are generally lower than those produced by fossil fuel-based power plants.
That is called "nuclear fusion".
Geothermal energy produces very low levels of greenhouse gas emissions compared to fossil fuels. While some emissions may occur due to the extraction and transportation of geothermal fluids, the actual operation of geothermal power plants is essentially emissions-free.
