Inexhaustible sources

Renewable energy sources do not end with their exploitation and theoretically can be used indefinitely. Examples include solar, wind and water energy and other resources that can be replenished such as timber or livestock.

HISTORY

Man has exploited the wind for thousands of years: the first windmills were built over 5000 years ago by the ancient Persians, and in the Middle Ages there were hundreds of them in the United Kingdom and Holland. Some were used to turn millstones that crushed grain into flour, while others were used to pump water from wells.

WHAT IS WIND ENERGY

Wind energy is a type of alternative energy source to that produced by the combustion of fossil fuels, renewable and economical, clean, which does not produce emissions of any type of greenhouse gas during operation and requires a large land area , the effects on the environment are usually less problematic than those from other energy sources

WHAT PRODUCES IT

A wind generator or wind turbine, commonly referred to as a wind blade, is an electro-mechanical structure or machine built to exploit/transform the kinetic energy of the wind (wind energy) into electrical energy through the use of blades. A group of wind turbines grouped in one place is called a wind farm.

HOW AND WHERE IT IS PRODUCED

Large wind farms consist of hundreds of individual wind turbines connected to the electricity transmission grid. Off-shore wind power is more stable, provides more energy and has less visual impact, however construction and maintenance costs are significantly higher. Small onshore wind farms provide electricity to isolated locations.

WHAT IS A WIND FARM

A wind farm is defined as a group of wind turbines located nearby and used for the production of electricity. A large wind farm may consist of several hundred individual wind generators spread over a large surface area, but the land between the turbines may also be used for agricultural or other purposes. A wind farm can also be located offshore.

WIND ENERGY IN ITALY

When we talk about Italian wind power, we are essentially talking about systems installed onshore

Italian plants are more concentrated in the South and generate a sixth of Italian green energy.

According to the data, Puglia alone offers a quarter of the national electricity power, to which are added 18% of Sicily, 14% of Campania, 13% of Basilicata and 10% of Calabria and Sardinia

43.4%

WHICH AND HOW MANY STATES PRODUCE WIND ENERGY

of electricity consumption came from wind in 2017

The country with the highest wind generation is Denmark,

There are at least 83 other countries in the world that regularly use wind energy for their electricity needs

MODERN WIND ENERGY

Today, wind energy is also used as another renewable energy source using wind turbines (modern windmills). The exploitation of the wind is highly dependent on the weather and location. Therefore it is convenient to install wind turbines in very windy places.

NON RENEWABLE SOURCES IN DECLINE

Renewable sources and energy efficiency are no longer niche sectors promoted only by governments and environmentalists. Increasing levels of investment suggest that sustainable energy has become mainstream and represents the future of energy production, while non-renewable sources decline. This is reinforced by concerns about climate change, nuclear dangers and the buildup of radioactive waste, high oil prices, peak oil and growing government support for renewables.
