Wind power is one of the fastest-growing renewable sources that works well at scale, but it isn’t perfect. What if we could scale down wind turbine power to something that could fit on your roof? And be self-contained with smaller moving parts … or maybe no blades or moving parts at all? Let’s look at some future alternatives for harnessing wind power.

Wind power is one of the fastest-growing renewable energy technologies. Usage is on the rise worldwide, in part because costs are falling. Global installed wind-generation capacity onshore and offshore has increased by a factor of almost 75 in the past two decades, jumping from 7.5 gigawatts (GW) in 1997 to some 564 GW by 2018, according to IRENA’s latest data. Production of wind electricity doubled between 2009 and 2013, and in 2016 wind energy accounted for 16% of the electricity generated by renewables. Many parts of the world have strong wind speeds, but the best locations for generating wind power are sometimes remote ones. Offshore wind power offers tremendous potential.
Wind turbines first emerged more than a century ago. Following the invention of the electric generator in the 1830s, engineers started attempting to harness wind energy to produce electricity. Wind power generation took place in the United Kingdom and the United States in 1887 and 1888, but modern wind power is considered to have been first developed in Denmark, where horizontal-axis wind turbines were built in 1891 and a 22.8-metre wind turbine began operation in 1897.
Wind is used to produce electricity using the kinetic energy created by air in motion. This is transformed into electrical energy using wind turbines or wind energy conversion systems. Wind first hits a turbine’s blades, causing them to rotate and turn the turbine connected to them. That changes the kinetic energy to rotational energy, by moving a shaft which is connected to a generator, and thereby producing electrical energy through electromagnetism.
The amount of power that can be harvested from wind depends on the size of the turbine and the length of its blades. The output is proportional to the dimensions of the rotor and to the cube of the wind speed. Theoretically, when wind speed doubles, wind power potential increases by a factor of eight.
Wind-turbine capacity has increased over time. In 1985, typical turbines had a rated capacity of 0.05 megawatts (MW) and a rotor diameter of 15 metres. Today’s new wind power projects have turbine capacities of about 2 MW onshore and 3–5 MW offshore.
Commercially available wind turbines have reached 8 MW capacity, with rotor diameters of up to 164 metres. The average capacity of wind turbines increased from 1.6 MW in 2009 to 2 MW in 2014.
Geothermal Energy is the energy obtained from the interior of the Earth. This energy is highly advantageous when compared to other energy forms as it produces 15% less greenhouse effect when compared to coal and is available 24 hours 365 days when compared to sources of energy like solar power and wind power. The availability of geothermal varies a lot and there are few places which are blessed with this form of energy. The electricity power generation plant based on geothermal energy are of dry steam type, flash type and binary type. This geothermal energy is also deployed to produce heating effect in winters and cooling effect in summers. Watch the video for more details.

Smart Energy Systems: 100% Renewable Energy at a National Level (Full Version)
Denmark has decided to become independent from fossil fuels. For the sake of the climate, the economy, and in order to ensure security of energy supply. This film shows how this will happen based on research conducted at Aalborg University (http://www.smartenergysystems.eu).
At present wind and solar energy already delivers a good share of Denmark’s energy, but renewable energy is a major challenge for an energy system that is built upon fossil fuels. Energy production from wind and solar fluctuates – it fluctuates as the wind blows. So what renewables are reliable when there is no sun or wind energy available?
Another challenge is the transport sector. How do we create an energy system of renewable energy, where also cars, ships and planes can operate on fossil-free energy? A great example of an energy system that will ensure Denmark a 100% renewable energy system is called: Smart Energy Systems – a coherent, fossil-free energy system that will create lots of new jobs and green energy for the Danes, both in terms of electricity, heat and transport.
