Why is wind energy indirect form of solar energy?
Wind energy is considered an indirect form of solar energy because winds are created by the uneven heating of the Earth's surface by the sun. As the sun heats the Earth's surface, different regions heat up at different rates, which causes air to move and generate wind. This wind energy is then harnessed using wind turbines to generate electricity.
What is the fastest a solar car can go?
In the summer of 2010, The University of Michigan's solar car Infinium reached a top speed of 105 mph (~169 kph) during vehicle testing.
The University of Michigan's Momentum solar car has reached speeds of over 90 mph (~145 km/h).
AT present these cars are not street legal. It is unlikely, that they ever will be due to the available energy from the sun verses the weight to make the car legal.
Why is molten salt used as one of the storage means in thermal storage?
Molten Salt can be heated to over 1000 degrees using mirrors and solar power. Molten salt only loses 1% of its heat in 24 hours which is allot better then most substances and therefore the heat energy is available at night and on cloudy days.
How much battery power would it take to power an electromagnet?
Any strength of power source can be used to make an electromagnet. A single AA battery, used well, can (at least briefly) power an electromagnet that can hold several pounds of metal in the air. An electromagnet's strength is determined by three factors: * the material in the core (air makes a weak magnet; iron a reasonably strong one) * the amount of current in the wire * the number of turns that the wire makes around the core The strength of an electromagnet is often referred to in "amp-turns": the number of turns times the amount of current it has. A simple battery approximates a voltage source: that AA battery pushes out about 1.5V of electricity. Divide that 1.5V by the resistance of the wire (longer wire higher resistance) and you get the current in the wire. At least, until your voltage source gives up and can't deliver that much current any more--then you need a new battery. :)

Which energy forms when tiny particles are released by atoms light heat electrial or solar?
The energy form that is released when tiny particles are released by atoms is heat energy. When atoms release tiny particles such as alpha or beta particles, they generate heat as a byproduct of the process.
What is one advantage of solar energy?
One advantage of solar energy is that it is a renewable and sustainable source of power, as sunlight is abundant and freely available. Solar energy also produces no greenhouse gas emissions when generating electricity, making it an environmentally friendly option for reducing carbon footprints.
What is the process that produces solar energy?
Solar energy is energy that is obtained from the sun. It is the most cleanest and renewable form of energy. Solar panels are placed on rooftops to absorb the sun's rays during prime hours. They are made up of photo voltaic cells that are capable of converting solar energy to heat energy.
Solar panels are typically black because they are designed to absorb sunlight more effectively. The dark color helps to enhance the absorption of light and convert it into electricity efficiently. Additionally, the black color helps the solar panels to blend in with rooftops and other surfaces where they are usually installed.
This is very difficult to answer as it would depend on:- 1. the capacity of the pump, 2. the temperature of the water, 3. the insulation on the container, 4. the heat input to the container and water. The problem is, that the water would cool down and freeze, which would reduce the evaporation to the point that there would be so little evaporation that it could take a from a couple of hours to a couple days.
What are some adverse affects of ultraviolet light?
Ultraviolet (UV) light can cause skin damage such as sunburn, premature aging, and an increased risk of skin cancer. Prolonged exposure to UV light can also lead to eye damage, including cataracts and other vision problems.
Solar power and wind power are similar because?
both solar power and wind power are renewable sources of energy that harness natural elements to generate electricity. They are clean and sustainable alternatives to fossil fuels, helping to reduce greenhouse gas emissions and combat climate change. Additionally, both technologies have seen advancements in efficiency and cost-effectiveness in recent years, making them increasingly popular choices for energy production.
Advantages of using solar energy?
Solar energy is renewable, meaning it is a sustainable source of power. It helps reduce electricity bills as sunlight is free. Solar energy also has a minimal environmental impact compared to fossil fuels, as it produces no greenhouse gas emissions.
Describe two methods for getting energy from sunlight?
1. Heat things. For example, heat water and store it in a tank. This can be used for taking a shower, washing laundry, etc. The water can get to temperatures of about 80-90 degrees Centigrade, i.e., near the boiling point of water. Another type of heating device is the solar stove, which you can use to cook food, bake cake, etc.
2. Use special electronic circuits (called solar cells) to generate electricity.
Are UV light and UV rays the same thing?
Yes, UV light and UV rays refer to the same thing - ultraviolet radiation. UV radiation is a type of electromagnetic radiation that is not visible to the human eye. UV light or UV rays are terms used to describe this form of radiation.
How does electric current work in solar panels?
Solar panels convert sunlight into electricity through the photovoltaic effect. When photons from sunlight hit the solar panel, they knock electrons loose from atoms in the panel's semiconductor material, creating an electric current. This current flows through the panel's circuitry and can be used to power devices or stored in a battery.
Are there different kinds of energy?
Yes, there are:
There might be more, but I am not sure.
SORRY BUT YOU ARE WRONG...
JUST TO CORRECT..
THESE ARE THE KINDS OF ENERGY:
Potential Energy- energy in rest
Kinetic Energy- energy in motion
And the others.. that's what you call, Forms of Energy.
I am sure with my answer! 101% sure!
- just want to share my knowledge about that. (:
In the us what percentage of electricity is derived from fossil fuels?
Currently around 71%:
About 49% of electricity is generated from coal, 21% from natural gas, and 1% from petroleum. Adding those together, you get about 71%.
Why do people use more energy when they work rather then when they sleep?
For the same reason that a car burns more gas when it is driving then when it is sitting still at idle. When you work you burn calories. When you rest you still burn calories but not nearly as much. If you want the fire to burn hotter you need more fuel or energy. Sorry it's not a technical answer but it still explains why.
What is a simple solar collector and how does it function?
A simple solar collector is typically a device that absorbs sunlight and converts it into heat, often used for heating water or air. It usually consists of a dark, absorptive surface enclosed in a transparent cover to trap solar radiation. When sunlight strikes the collector, the absorptive surface heats up and transfers that heat to a fluid circulating through the collector, which can then be used for various applications.
Heat energy is the transfer of thermal energy between objects due to a difference in temperature. It flows from an object at a higher temperature to one at a lower temperature until thermal equilibrium is reached.
How can biomass be converted into electrical energy?
Biomass, which usually means recently dead plant material, is considered a renewable energy source, as it can be continually grown, removing carbon dioxide (CO2) from the air, and then releasing the same amount when it is burnt.
It is used in electricity power plants just like coal, to generate electricity. The heat produced by burning biomass drives electro-mechanical generators which produce electricity.
Coal is a non-renewable fossil fuel, made from the same dead plant material, but millions of years ago.
Yes, energy can be transformed from one form to another. This principle is known as the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted into different forms. Examples of energy transformations include the conversion of mechanical energy into electrical energy in a generator, or the transformation of chemical energy into thermal energy during combustion.
Does the size of a solar oven effect the heat?
Yes, the larger the surface area of the solar collectors (either focused reflectors or concentrating lenses), the more solar energy is put into the oven. Same thing for a magnifying glass in the hot sun -- the larger the magnifying glass, the hotter the focused spot of sunlight will be.
However, if you are talking about the size of the oven itself (for example an oven that can cook one dish compared an oven for 100 loaves of bread), then clearly the larger the oven, the more energy you need to heat it. So the larger the oven part itself, the lower the heat for the same size reflectors. But usually large ovens have large solar collectors for this reason.
What percentage of the world's electricity is generated by nuclear power?
