Wood is not a fossil fuel (they are coal, oil and natural gas).
Renewable energy sources such as solar, wind, hydro, and geothermal power are considered the opposite of fossil fuels. These sources are considered sustainable and have lower environmental impacts compared to fossil fuels.
Both wind power and fossil fuels are used to generate electricity. Additionally, they both have the potential to impact the environment, although wind power is considered cleaner and more sustainable compared to fossil fuels.
Most rockets today use liquid oxygen and liquid hydrogen as fuel, not fossil fuels. These fuels react to produce water vapor and can be considered eco-friendly compared to fossil fuels. However, some rockets still use a combination of liquid oxygen and kerosene as fuel, which is a fossil fuel.
natural gas,fossil fuels
Alternative fuels are renewable and produce fewer greenhouse gas emissions compared to fossil fuels, such as gasoline and coal, which are non-renewable and contribute significantly to air pollution and climate change. Examples of alternative fuels include biofuels, hydrogen, and electricity. Overall, alternative fuels are considered more sustainable and environmentally friendly than fossil fuels.
It really depends what is considered "important". Less important "economically" currently are the the renewable, sustainable sources like wind and solar power as they represent a small fraction of the energy produced compared to the non-renewable and depleting fossil fuels like oil, coal and gas. However for the health of our planet and possibly for our survival, fossil fuels are not only less important but they are a dangerous hazard as they are responsible very bad problems with our environment like global warming. And of course as they become severely depleted in the future fossil fuels will become less important economically too.

Fossil Fuels
Fossil fuels have never been considered renewable resources because they are formed over millions of years from the remains of ancient plants and animals. Renewable resources, like solar and wind energy, are constantly replenished and do not deplete over time like fossil fuels do.
Fossil fuels are the most important aspect of their economies. Indonesia is a member of OPEC and Brunei has become very wealthy because of fossil fuels.
Solar energy is considered better than fossil fuels because it is a renewable and clean source of energy that does not produce harmful greenhouse gas emissions, unlike fossil fuels which contribute to climate change and air pollution.
