Non-renewable energy sources such as oil, gas and coal seem to be declining rapidly, although new ones are sometimes discovered. At the same time, there is a global shift towards renewable energy. For example, in Europe alone, renewables accounted for almost 90% of the new energy added to the grid in both 2016 and 2017.

The future of renewable energy
What is renewable energy?
Just speaking of renewable energy, it means energy from sources that are tireless and replenished naturally. However, renewable energy is often limited in supply. What this means is that while renewable resources are almost completely inexhaustible in their entire supply. But the amount of energy available per unit of time is limited in the United States.Renewables contributed 11% of total energy use in 2017.
What are the different renewable energy sources?
Solar energy uses nuclear fusion energy from the sun’s core. Solar energy can be used in a variety of applications. They range from heaters and home lighting to water heaters, solar attic fans, and more. However, most of the solar energy is not yet used. For example, in the US, solar energy is less than 1% of electricity.
The heat of the sun (Plus the moon’s clouds on the tides) help drive the wind. Wind turbines are used to capture energy from these winds. Wind energy can be used to generate electricity and pump water. However, wind power can only be used in areas with favorable conditions. Wind farms also cover large areas to generate large amounts of the required energy. Some windmills move out to the sea to make the wind stronger.
Wood burning produces large amounts of carbon dioxide, which is plant food. Today’s promising biomass includes biodiesel, methane and ethanol. Gas can use any material that depends on vegetation and extract the gas for incineration.
It increases the gravitational potential of water at the same height as moving water. Hydroelectric power can be anywhere there is fast or moving electricity, and it can be on an industrial or personal scale. (As with most renewable energy options)
This energy can be used to heat or cool buildings and generate electricity. However, geothermal energy has been tapped in very confined areas of the world where conditions are optimal, technical limitations prevented geothermal energy from penetrating into large renewable energy sources to this day. But new technologies can change that.
Hydrogen and fuel cells
One of the advantages of using hydrogen as an energy source is that its burning hardly creates pollution. When used as a car fuel or powered by a hydrogen battery, it can help reduce pollution considerably. An experiment to use solar energy to produce hydrogen It can become a very important source of energy.
What is the main benefit of renewable energy?
There is great pressure on fossil fuels today. Affordable and efficient renewable energy sources complement the supply of fossil fuels to support more sustainable energy models. It is not surprising that the use of renewable energy has increased five to six times since the 1960s.Here are some of the main benefits of renewable energy:
Possible cost savings
While most renewables require a higher upfront investment. But it’s more cost effective in the long run. The first reason is that it has lower operating costs. For example, if you use solar or wind energy, you won’t have to pay regularly to refuel. In addition, renewable energy technologies often require very little maintenance, saving you the cost of recurring maintenance. The cost of grid-connected fuel and electricity also exceeds the cost of renewable energy over the long term.
Renewable energy technologies use local resources such as sunlight and wind to generate electricity. The more citizens of the country begin to use renewable energy, the less their dependence on imported and central energy will be.
Renewable resources are almost inexhaustible.
Unlike fossil fuels, there is no risk that renewables such as sunlight, wind and water will soon run out.This makes renewables a great addition to fossil fuels. Using renewable energy wherever possible can significantly reduce the burden of fossil fuels.
An example of being off the grid
Living off the grid can be frightening. However, many people are using the latest technology to get off the grid in a modern and sustainable way. Here are some examples from around the world:
Van Geet’s offline home
Van Geet Home is backed by the U.S. Department of Energy’s Energy Efficiency and Renewable Energy Agency (EERE). This off-grid house near Denver, Colorado, experiences more than 300 days a year, enabling massive power generation from just two solar panels. In addition, the home site makes use of passive solar energy and sunlight to provide the least amount of energy to operate the home.
Sundby Nature House
This greenhouse was built for families in Stockholm. He’s doing a great job of using greenhouses for production instead of energy. The house is completely powered by nature and uses the latest technology such as solar cells.
National Renewable Energy Laboratory
The National Renewable Energy Laboratory (NREL) is a good example of a step forward in renewable energy.NREL is funded by the Ministry of Energy but managed by MRIGlobal under a contract to fund research on emerging renewable technologies from It works with a personal partner to trade. These partnerships take the form of technology licensing, strategic partnership programs, and joint research and development agreements.
