Presentation transcript:

Introduction Energy resources in agriculture have evolved a lot over the years. We are constantly developing new greener energy sources that are beneficial in in the future. Our presentation features some energy sources used in farming today. We hope you learn some facts about the different energy sources. Enjoy the show.

- The flow of electrons and protons attracting the opposite charge electricity energy: A general term encompasses a variety of phenomena resulting a flow of electric charge -uses: lighting, heating and appliances

-Formed from remains of dead plants and animals -Produce comparatively little pollution -20% of world’s energy consumption -uses: fuel, heating

-when sunlight passes a window, hits an object and is converted into thermal energy or electrical energy -renewable, but expensive

-burned in a furnace or boiler to generate heat -uses includes: heating homes, fuel for trucks and farm vehicles, fertilizers

-The use of gravitational force of falling water -renewable energy (water is from nature) - reduces greenhouse gas emissions -Generates electricity

-can be man made or natural -coal and oil are used to provide electricity -16% of worlds electricity

-heat extracted from the earth -steam and hot water produced inside the earth is used to heat buildings or generate electricity -renewable: rainfall is from nature and heat is always there in the earth

-uses: fuel for engines, trains automobile, aircraft, boats and construction vehicles -contains less sulphur -disadvantage: contains greenhouse gas, produces lots of air pollution

-recycled cooking oil form restaurants -organic matter turned into fuel -uses: motor fuel, diesel vehicles

-energy stored in non-fossil organic materials (ex. Straw, wood, vegetable, oils, manure, garbage) -Stored energy from the sun -steam makes electricity when burned

-vaporized water -energy storage extracted by heat transfer by pipes -uses: engines, turbine, cooking, cleaning of fabrics and carpet, heating buildings
