What is green technology? In 2023, green technology can feel like the new kid on the block. But the world of sustainable innovation has a long history you probably didn’t know about.Take geothermal heating, a popular trend in energy-efficient homes and buildings. Using heat energy from below the earth’s surface dates back to Paleolithic times, when early humans bathed in hot springs and built homes from lava. Or take wind energy — as early as 5000 B.C., our ancestors were using wind energy to move boats down the River Nile
So humans have been working on sustainable solutions for everyday needs for a long time. But today, innovative solutions to our environmental problems is now more popular — and more necessary — than ever.

Green technology actually mean “any technology designed to reduce the negative impact of human activity on the environment”

is any energy type that is generated from natural resources, such as sunlight, wind or water. It often comes from renewable energy sources although there are some differences between renewable and green energy

The key with these energy resources are that they don’t harm the environment through factors such as releasing greenhouse gases into the atmosphere

Types

 

 

 

 

The main sources are wind energy, solar power and hydroelectric power (including tidal energy, which uses ocean energy from the tides in the sea). Solar and wind power are able to be produced on a small scale at people’s homes or alternatively, they can be generated on a larger, industrial scale

 

 

 

 

 

 

 

 

 

 

This common type of renewable energy is usually produced using photovoltaic cells that capture sunlight and turn it into electricity. Solar power is also used to heat buildings and for hot water as well as for cooking and lighting. Solar power has now become affordable enough to be used for domestic purposes including garden lighting, although it is also used on a larger scale to power entire neighbourhoods.

Wind Powers

 

 

Particularly suited to offshore and higher altitude sites, wind energy uses the power of the flow of air around the world to push turbines that then generate electricity.

 

 

 

Also known as hydroelectric power, this type of green energy uses the flow of water in rivers, streams, dams or elsewhere to produce electricity. Hydropower can even work on a small scale using the flow of water through pipes in the home or can come from evaporation, rainfall or the tides in the oceans.
Exactly how ‘green’ the following three types of green energy are is dependent on how they are created…
