Key Concepts

Nonrenewable Energy

Nonrenewable energy sources, such as coal and oil, are considered nonrenewable because they were formed over millions of years and cannot be quickly replenished on a human timescale. Once these fossil fuels are extracted and used, the energy stored within them is gone, making their supply finite.

Solar Energy

Solar energy is the ultimate source of energy for all life on Earth. It drives natural processes such as photosynthesis, where plants convert sunlight into chemical energy, and it is ultimately responsible for the formation of all energy-rich materials, including those found in fossil fuels and wood.

Photosynthesis

Photosynthesis is the process by which plants, algae, and certain bacteria capture energy from sunlight and convert it into chemical energy stored in sugars. This stored energy forms the basis of the energy content in organic matter, including wood and, indirectly over geological timescales, fossil fuels like coal and oil.

Fossil Fuels

Fossil fuels, such as coal and oil, are formed from the remains of ancient organisms that captured solar energy billions of years ago through photosynthesis. Over long periods, these organic materials were subjected to heat and pressure, transforming them into concentrated forms of chemical energy that are now used as nonrenewable energy sources.

Renewable Energy

Renewable energy refers to energy sources that can be naturally replenished on a human timescale. Energy from wood is considered renewable because trees and plants continue to grow and capture solar energy, allowing for a sustainable cycle of energy production that can be maintained with proper management.
