Not quite sure of your parsing, but solar cells on the roof seem to convert some light into electricity.
electricity generation
The generation of electricity.
Benjamin Franklin started off a lightning rod and mad Electricity when the lighting hit it and made Electricity and pat it on from generation to generation.
Process heat and electricity generation.
You are probably thinking of hydroelectric, which refers to the generation of electricity by the use of dams and waterfalls.
Electricity generation through photovoltaic and/or CSP technique.
The most common use for nuclear energy is electricity generation in nuclear power plants. These plants use the heat produced by nuclear fission to create steam, which drives turbines to generate electricity.
Today, the main use of coal in the United States is related to electricity generation and industry.
Our eyes are our sense organ for detecting light. Their colour range is somewhat limited, being about one half of an octave. When we say we 'see something', or 'are looking at something', in reality we are merely receiving light from that object. We use separate sensors for brightness, and for colour. For colour we have three different colour sensors, which overlap in their bandwidth. Thus we perceive a broad range of colour. In dim light, our colour sensors are not active. Your eyes are an extension of your brain (whose whole surface is light sensitive), and each eye sends part of its output to both hemispheres of the brain. Many herbivores and carnivores have little use for colour, and waste no brain power on it. Some insects and butterflies can see a much wider range of colours that humans do.
People use a lot of electricity, and often need to obtain it from many different sources in order to get enough. It is also true that windmills have other uses than the generation of electricity, and they were in use centuries before electricity came into use. You can mill grain without electricity, by connecting millstones to an axle, which is turned by the wind.
Two ways we use energy are for electricity generation and transportation. Electricity generation involves converting energy into electricity for various applications, while transportation involves using energy to power vehicles for movement from one place to another. The main difference is the end use of the energy, with electricity for powering devices and transportation for moving people or goods.
The generation of electricity can have environmental impacts, depending on the source of the electricity. Fossil fuel-based power plants produce greenhouse gas emissions and air pollution. Renewable energy sources like solar and wind have lower environmental impacts. Conserving energy and using it efficiently can help reduce the environmental damage associated with electricity generation.
