Chapter 18 – Energy Production
Biomass and fossil fuels
Biomass is plant matter used as fuel to produce energy
Fossil Fuels once living plant matter used as energy. eg. Oil, Coal, Natural Gas
Nuclear, tidal and geothermal power
Nuclear: Process of cosmic evolution preceding the origins of the solar system
Tidal Power: The forces of lunar motion
Geothermal Power: Energy from the Earths core
Cogeneration
The generation of electricity and heat jointly by using wasted energy (Hot water) from conventional electricity. This hot water can be used for heating Renewable energy
Forms of energy that can naturally regenerate or are continues Hydropower
Mechanical Power of moving water to turn turbines to produce energy,
Wind energy
Generation of wind-derived electricity, using wind gush to turn turbines
Solar power (361)

Generating electricity from the suns energy.
Passive solar energy
Designing buildings that optimize suns light and heat
Thermal electric generation
Solar Radiation that is tracked by mirrors that concentrate the suns rays in order to heat liquid inside the pipes
Photovoltaic energy
PV power is produced when individual light particles “photons” are absorbed in a semiconductor such as silicon to create an electric current
Processed and unprocessed Biomass
Plant matter used as fuel
Processed: (Charcoal, methane from biogas plants)
Unprocessed: (wood, dung, veg matter and agriculture wastes)
Tidal power
Energy from the ocean found in forms of tides, waves, currents, etc. using the forces of lunar motions
Tides ebb and flow because of the gravitational interaction between the sun, moon and earth and the centrifugal force of the earth-moon system
Geothermal energy
Energy tapped from the heat which flows outwards from the earth interior energy, both from its core as it cools and from the decay of long lived radioactive
