• Renewable resources - are resources that are replenished naturally in the course of time.
• non-renewable resources - are those that are available to us in limited quantities
• Energy - in physics is the capacity for doing work
• Fossil fuel - is a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms
• Biogas - contains stored energy from the sun. Plants absorb the sun's energy in a process called photosynthesis
• Greek ”geo” meaning earth and ”therine” meaning heat
• Geothermal power - is cost-effective, reliable, sustainable, and environmentally friendly, but has historically been limited to areas near tectonic plate boundaries.
• Hydropower energy - comes from a Greek: hydro, which means "water". It is derived from the energy of falling or fast-running water. This energy can be harnessed by the power of moving water.
• Battery - is a device that stores chemical energy and converts it to electrical energy
• Coal - fossil fuel
• Energy is released from fossil fuels when they are burned
• Hydroelectricity power potential energy is transformed to kinetic energy.
• Energy in the form of heat and light is obtained from Sun
• Biomass - . This kind of energy is produced from raw materials such as agricultural waste, manure, municipal, waste or food waste
• Hydropower - An energy from falling or fast-running water which may he harnessed for useful purposes
• Biomass - is plant or animal material used for energy production in various industrial processes as raw substance for a range of products
• Solar cell - is an electrical device that converts the of energy light directly into electricity by the photovoltaic effect, which is physical and chemical phenomenon
• Wind power - It uses wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping.
