Humanity has always needed energy for work and production. For most of history, this energy came from human and animal labor, such as blacksmiths, artisans, and horse-drawn carriages or oxen working the farm fields. This changed with the Industrial Revolution and its boom in technology, production, and energy needs. Steam power and machines became dominant, and pressurized steam allowed turbines to be rotated for energy. Later in the 1800s, electricity was harnessed, adding even more power and enabling more inventions. In the 20th centuries, fossil fuel-powered power plants could be found across the industrialized world, along with nuclear power.
Now in the 21st century, there has been some increasing concern about the sheer pollution that traditional power plants create, such as emissions into the air. To counter-act this and take advantage of new technology, engineers have pioneered clean energy sources such as solar power, and solar companies can install these panels right onto
