Climate Change
The average climate over the entire planet.
What is Global Climate?
Refers to ALL the energy used to live or work a building.
What is meant by energy consumption?
The rate of producing or consuming energy.
What is power?
Resources Mother Nature can replace, like wind, water and sunshine. These sources cause little to no pollution and will last thousands, or maybe even millions, of years.
What is "renewable resources"?
This refers to harnessing the wind to produce energy that is converted into electricity that we can use in our homes and other buildings.
What is the purpose of a wind turbine?
The temperatures, rainfall, wind and other conditions over a larger region and over a longer period of time.
What is climate?
Stored energy or energy held by an object such as an arrow in a bow ready to launch.
What is potential energy?
The rate of doing work. Power is energy per unit of time.
What is power?
These are resources that when used, are used up and can not be made again by Mother Nature. Rock, minerals, metals, uranium, and fossil fuels such as petroleum, coal, and natural gas are all nonrenewable resources.
What is meant by non-renewable resources?
The energy in the wind turns propeller-like blends around a rotor. The rotor is connected to a main shaft that spins a generator to create electricity.
How does a wind turbine work?
The temperature, rainfall, wind and other conditions in a local area and it is temporary.
What is weather?
Refers to the movement of atoms, molecules, waves and electrons.
What is kinetic energy?
No, Power is 'watt' and Energy is 'watt-hour'. The watt-hour (symbolized Wh) is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time.
When referring to electrical power and energy, are they the same?
These are main types of fossil fuels: coal, oil, and natural gas.
What are our main sources of energy today?
Wind turbines convert the kinetic energy from the wind into mechanical power. The generator converts this mechanical power into electricity.
What is the purpose of the generator on a wind turbine?
Also called global warming. Refers to the rise in average surface temperatures on Earth.
What is climate change?
The movement of electrons.
What is electrical energy?
The unit of power whereas kilowatt-hour (kWh) is the unit of energy.
What is the difference between Watt and Kilowatt-hour (kWh)?
These sources can cause pollution. Burning fossil fuels releases chemicals into the air and water.
Using nonrenewable energy sources can cause what?
This a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly.
What is a nacelle on a wind turbine?
Primarily due to the human use of fossil fuels, which releases carbon dioxide and other greenhouse gases into the air. The gases trap heat within the atmosphere, which can cause a rise in sea levels, severe weather events, and droughts that render landscapes more susceptible to wildfires.
What are causes and the impact on the environment of climate change?
The amount of useful energy you get from a system and is not wasted.
What is meant by energy efficiency?
Electrical companies multiply the total energy usage kWh with charge per kWh (This should be on your electricity bill), to get your total Electricity cost.
How do electrical companies charge you for the electricity you use?
If we are still dependent on using non-renewable resources, we will not have enough energy to meet our needs in the future.
Why is switching to using renewable resources important to our future?
This is typically used in a wind turbine to increase rotational speed from a low-speed rotor to a higher speed electrical generator. This is connected to the main shaft, which spins a generator to create electricity.
What is a gearbox and a rotor?
