Which of the following is NOT a fossil fuel? A. coal B. petroleum C. wood D. methane

Renewable resources are natural resources that can be replenished naturally over time. Unlike fossil fuels, which take millions of years to form, renewable resources are often available continuously or can be restored within a human lifespan. Examples include:

• Solar energy
• Wind energy
• Biomass (like wood)
• Hydropower

Wood, as mentioned in the exercise, is a renewable resource because it comes from trees that can be replanted and regrown. This is what makes it different from fossil fuels like coal and petroleum, which can't be renewed in a short time frame. The use of renewable resources helps reduce pollution and dependence on non-renewable energy sources.
Investing in renewable energy technology is crucial for a sustainable future and helps mitigate the adverse effects of fossil fuel consumption on the environment.

Energy sources are materials or phenomena that can produce power. Understanding the distinction between non-renewable and renewable energy sources is essential for grasping the concepts in this exercise. Non-renewable energy sources include fossil fuels like coal, petroleum, and natural gas. These are finite resources formed from ancient organic matter. Renewable energy sources, on the other hand, are much more diverse and can be replenished. Some benefits of renewable energy sources include:

• They are less harmful to the environment.
• They can reduce our reliance on fossil fuels.
• They have the potential to be more cost-effective in the long-run.

By exploring options like solar, wind, and hydropower, we can create a more balanced and sustainable energy portfolio.

Organic matter refers to any carbon-based material derived from living organisms. In the context of fossil fuels, organic matter is the remains of ancient plants and animals that have been buried and subjected to heat and pressure over millions of years. This process transforms the organic material into fossil fuels. Examples of organic matter forming fossil fuels include:

• Dead plants turning into coal
• Marine organisms becoming petroleum
• Plant material decomposing to generate methane

Unlike fossil fuels, organic matter from current living organisms (like wood from trees) decomposes naturally and is part of a quick, renewable cycle. Because it can be readily replenished, using organic matter from current-day sources as an energy resource is generally more sustainable. Understanding these distinctions is vital for making informed choices about energy use and sustainability.
