electricity generation

Title Post date
Renewable Energies Keywords: biofuel, electricity generation, energy, hydro-electricity, Renewable, solar energy, wind energy

Energy is always required, whether it be for the production of goods, the supplying of services, or for transportation. Can we reduce our emissions by turning to clean sources of energy? If so, why haven't we already?

A large portion of humanity's energy demands are met using fossil fuels. Switching from fossil fuel generation to cleaner sources could greatly reduce the carbon emission put out every year. There are many ways to obtain energy cleanly, each with their own advantages and challenges.

Light Bulb Efficiency and Hand Crank Energy Generation Keywords: breadboard, circuit, efficiency, electricity generation, energy, energy conversion, Lend an Experiment (LEx), lighting

What does it really take to power a light bulb?

This activity is part of the LEx (Lend an Experiment) Climate Kit. Students compare the power consumption of incandescent and LED bulbs through the use of hand crank generators and a simple circuit. Concepts include the conversion of mechanical to electrical energy, power and efficiency, and measurement estimation. There is an option to also investigate the efficiency of the hand crank generator.

Generating Electricity: Wind and Water Keywords: electricity, electricity generation, hydro-electricity, Lend an Experiment (LEx), wind, wind energy, wind turbines

A match made in energy heaven, wind and water are wonderful sources of clean, renewable energy. Let us see what goes into this electricity generation by making some wind and water turbines ourselves!

This activity is part of the LEx (Lend an Experiment) Climate Kit. Students generate their own wind or hydro electric power by constructing wind/water blades, exploring how mechanical energy from external sources can be harnessed and turned into electrical energy. The effect of different gear ratios can also be explored.

Generating Electricity Keywords: coils, electricity, electricity generation, magnetic field, magnets

Generating electricity using just a magnet and a wire?

A useful voltage can be obtained by moving a wire perpendicularly through a magnetic field; the electrons in the wire are pushed to one side creating a flow of electricity which is perpendicular to both the magnetic field and direction of wire motion.
