The old fashioded way: kite+key+crazy guy+storm=electricity
or
placing wires in a lemon and around a light bulb. It's a pretty cool experiment if you haven't tried it yet.

List of examples of energy conversions1. Electric Generator (Mechanical Energy into Electrical Energy)2. Electric Motor (Electrical Energy into Mechanical Energy)3. Steam Engine (Thermal Energy into Mechanical Energy)4. Diesel or Petrol Engine (Chemical Energy into Mechanical Energy)5. Stove (Chemical Energy into Thermal Energy)6. Electric Bulb (Electrical Energy into Thermal and Light Energy)7. Cellular Respiration (Chemical Energy into Thermal and Mechanical Energy)
What are the basic steps involved in generating electricity at a power plant?
In all power-generating schemes except solar, some other form of energy is used to produce electrical energy by turning a mechanical generator.
How much amount of heat will produce in 22kilo ohm resistor?
If the resistor is conducting electrical current, then the power it dissipates (heat energy per second) is(current through it)2 times (22,000)or(voltage across it)2 divided by (22,000).If the resistor is connected in an unpowered circuit, or stored in a drawer, then it dissipates zero heat.
What are 2 ways recycling can reduce energy use?
Recycling reduce the energy of processing raw material and made into the product, it also reduce the energy required for the waste management process.
Name 5 sources of heat energy?
Fossil fuels - coal, oil, natural gas. Biomass (including wood and charcoal). Nuclear power. Solar power. Geothermal power(volcanosVolcanoes, hot springs and geysers are sources of geothermal energy - energy from the interior of the earth. The thermal energy from these events can produce hot water or steam, which can be then piped to a power plant at the surface. This can be used to run turbines which produce electrical energy. HRD (hot, dry rock) can be used as another technique to generate thermal energy. (Water is pumped into cracks in the earth's crust. It returns to the surface as steam, which can be used to generate electricity).
What are 2 ways the ocean can provide energy?
Wave action and tidal currents are being utilized today to produce electrical energy.
What are 2 common energy conversions that involve electrical energy?
electrical-sound electrical-thermal
What can electrical energy be converted?
Electrical energy can be converted to: 1. Heat energy 2. Light energy and many more
What can Electrical energy be converted to?
Electrical energy can be converted to: 1. Heat energy 2. Light energy and many more
When a pendulum swing stops its energy is changed into what?
A pendulum will lose energy in two ways: 1. by friction with the air, 2. by friction in its supporting bearing. Both these energy losses will produce heat.
What 2 forms of energy are created by waves?
No form of energy is ever created, you can only change one form into another. Waves come in many forms, and all of them carry energy, which can be transformed into other kinds of energy. Water waves, for instance, carry kinetic energy which can drive a generator to produce electrical energy, as well as waste heat energy. Light energy travels as waves, and this can be changed by a solar cell into electrical energy, or by a plant into chemical energy.
How does coal produce electricity?
Coal makes energy in 6 sorta simple steps. 1) The coal or natural gas is first burned for mainly thermal (or heat) energy. 2) That thermal energy is used to boil water and to produce steam. 3) That steam is then forced through a high pressure tube called a steam line. 4) The steam then pushes a turbine (which is very electrical and i don't know what goes on in there) 5) That turbine then produces electrical energy. 6) The electrical energy is transported to your home and then you use it for searching the internet on how coal makes energy! (how convenient!)
What 2 factors are needed to measure usage of electrical energy in buildings?
size of the buildng and what the buildings is using to pull on the electrical energy
How is solar energy transformed into other types of energy?
There are two main ways to convert solar energy into other forms of energy. 1. Photovoltaic Conversion Photovoltaic cells, called solar panels, use the photovoltaic effect to convert sunlight into electricity. Photovoltaic cells in solar panels produce electricity by way of electron excitation caused by solar radiation. Both home and business applications frequently use this kind of energy conversion. 2. Thermal Conversion With the help of solar thermal systems, heat produced by the sun can be transformed into mechanical or electrical energy. Solar energy can be converted into mechanical, thermal, or electrical energy to suit a variety of energy needs in diverse industries.
What is a common energy transformation?
There are 6 kinds of transformatons: 1.Mechanical Energy 2.Thermal Energy 3.Chemical Energy 4.Electrical Energy 5.Electromagnetic Energy 6.Nuclear Energy The most common is probably Mechanical or Electrical.
When a fuse wire melts the electrical energy is transfered as what 2 types of energy?
kinetic and chemical energy
Where do orginisms get energy from?
There are 2 ways, 1.obtaining chemical energy 2.obtaining light energy
