Which energy is best and why?
Often ranked as one of the most efficient energy sources, wind energy is harnessed all over the world. Of course, some spots are known as being windier than others, and companies typically make use of these spots by building wind farms filled with turbines there. Wind energy has also been used for hundreds of years.
Energy is essential to life and all living organisms. The sun, directly or indirectly, is the source of all the energy available on Earth. Our energy choices and decisions impact Earth's natural systems in ways we may not be aware of, so it is essential that we choose our energy sources carefully.
Two sources provide more than 99 percent of the power for our civilization: solar and nuclear. Every other significant energy source is a form of one of these two. Most are forms of solar.
Energy from the Sun fuels life on Earth
The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates.
As you can see, nuclear energy has by far the highest capacity facto r of any other energy source.
Fossil fuels are the largest sources of energy for electricity generation.

All living organisms need energy to grow and reproduce, maintain their structures, and respond to their environments. Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes.
Energy is the ability to do work. It is needed by all living things and every living cell to carry out life processes, such as breaking down and building up molecules, and transporting many molecules across cell membranes.
Like an automobile only runs on gasoline, the human body runs on only one kind of energy: chemical energy. More specifically, the body can use only one specific form of chemical energy, or fuel, to do biological work – adenosine triphosphate (ATP).

Energy Sources in the United States
Natural gas: 31.8% Petroleum (crude oil and natural gas plant liquids): 28% Coal: 17.8%
Some of the renewable energy sources are solar energy, wind energy, biomass and hydropower energy. It is called renewable because it is sustainable. It is also referred to as alternative energy as these are the alternatives of non-renewable energies.
Primary energy sources include fossil fuels (petroleum, natural gas, and coal), nuclear energy, and renewable sources of energy.

The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.
Energy is essential for most activities of modern society. Its use or consumption is generally taken as an index of standard of living. We use energy in the form of fire wood, fossil fuels and electricity to make life comfortable and convenient.
These essential functions include: the heartbeat, metabolism of foods, respiration and regulation of water and body temperature.
Without energy, life would be impossible. There are different forms of energy. Potential energy is energy that is stored somewhere. A raised ball, for example, has potential energy by virtue of its position relative to the Earth.
What will happen without energy?
There would be no power to use your fridge or freezer, telephone lines would be down and phone signal lost. Your mobile phones will be useless as the battery dwindles, with no back up charging option. Your gas central heating won't work and your water supply would soon stop pumping clean water.
How do energy labels work? Appliances are tested for how much energy they use during typical use. This gives them a rating on a scale of A to G, with A being the most efficient product of its class, and G being the least efficient. Some appliances use an older scale, from A+++ to G, with A+++ being the most efficient.
Nuclear energy, for example, results in 99.9% fewer deaths than brown coal; 99.8% fewer than coal; 99.7% fewer than oil; and 97.6% fewer than gas. Wind and solar are just as safe.
Wind power is a clean and renewable energy source.
Not only is wind an abundant and inexhaustible resource, but it also provides electricity without burning any fuel or polluting the air. Wind continues to be the largest source of renewable power in the United States , which helps reduce our reliance on fossil fuels.
Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels.
Renewable Energy. Renewable energy is derived from natural processes that are replenished constantly such as solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen.
- Sun (solar radiation) is the biggest source of energy on Earth's surface.
- It is also known as the ultimate source of energy on Earth's surface because we know that green plants use sunlight for photosynthesis, which is the process by which they make food for their growth.
The different types of energy include thermal energy, radiant energy, chemical energy, nuclear energy, electrical energy, motion energy, sound energy, elastic energy and gravitational energy.

Provides clean, renewable energy
Home solar is a clean, emissions-free, and renewable energy source. Unlike fossil fuels such as coal and natural gas, home solar doesn't release harmful pollutants or greenhouse gas emissions—like carbon dioxide—into the air and water supply.
What's better solar or wind power?
Wind is a more efficient power source than solar. Compared to solar panels, wind turbines release less CO2 to the atmosphere, consume less energy, and produce more energy overall. In fact, one wind turbine can generate the same amount of electricity per kWh as about 48,704 solar panels.
As carbon-free and renewable energy sources, wind and solar can help reduce the world's dependence on oil and gas. These carbon fuels are responsible for harmful greenhouse gas emissions that affect air, water and soil quality, and contribute to environmental degradation and climate change.
The advantages of nuclear power are:
It also has one of the smallest carbon footprints. It's one of the answers to the energy gap. It's essential to our response to climate change and greenhouse gas emissions. Reliable and cost-effective.
