The Sunforce 44444 400 Watt Wind Generator uses wind to generate power and run your appliances and electronics. Constructed from lightweight, weatherproof cast aluminum, this generator is also a great choice for powering pumps or charging batteries for large power demands. With a maximum power up to 400 watts or 27 amps, this device features a fully integrated regulator that automatically shuts down when the batteries are completely charged. The 44444 is virtually maintenance free with only two moving parts, and the carbon fiber composite blades ensure low wind noise while the patented high wind over speed technology guarantees a smooth, clean charge. Assembly is required, but this generator installs easily and mounts to any sturdy pole, building, or the Sunforce 44455 Wind Generator 30-Foot Tower Kit. The 44444 uses a 12-volt battery (not included) and measures 27 x 44 x 44 inches (LxWxH)

So how do wind turbines make electricity? Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity. View the wind turbine animation to see how a wind turbine works or take a look inside.

Renewable electricity production, from sources such as wind power and solar power, is sometimes criticized for being variable or intermittent, but is not true for concentrated solar, geothermal and biofuels, that have continuity. In any case, the International Energy Agency has stated that deployment of renewable technologies usually increases the diversity of electricity sources and, through local generation, contributes to the flexibility of the system and its resistance to central shocks.[191]

In 2011 Mark Z. Jacobson, professor of civil and environmental engineering at Stanford University, and Mark Delucchi published a study on 100% renewable global energy supply in the journal Energy Policy. They found producing all new energy with wind power, solar power, and hydropower by 2030 is feasible and existing energy supply arrangements could be replaced by 2050. Barriers to implementing the renewable energy plan are seen to be "primarily social and political, not technological or economic". They also found that energy costs with a wind, solar, water system should be similar to today's energy costs.[153]

In 2014 global wind power capacity expanded 16% to 369,553 MW.[83] Yearly wind energy production is also growing rapidly and has reached around 4% of worldwide electricity usage,[84] 11.4% in the EU,[85] and it is widely used in Asia, and the United States. In 2015, worldwide installed photovoltaics capacity increased to 227 gigawatts (GW), sufficient to supply 1 percent of global electricity demands.[86] Solar thermal energy stations operate in the United States and Spain, and as of 2016, the largest of these is the 392 MW Ivanpah Solar Electric Generating System in California.[87][88] The world's largest geothermal power installation is The Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18% of the country's automotive fuel. Ethanol fuel is also widely available in the United States.
Renewable energy power plants do provide a steady flow of energy. For example, hydropower plants, ocean thermal plants, osmotic power plants all provide power at a regulated pace, and are thus available power sources at any given moment (even at night, windstill moments etc.). At present however, the number of steady-flow renewable energy plants alone is still too small to meet energy demands at the times of the day when the irregular producing renewable energy plants cannot produce power.
The comments stand in contrast to those made by Trump administration representatives also speaking at the energy summit, which is known as CERAWeek. Rick Perry, the energy secretary, on Wednesday criticized what he described as the “mind-set of the Paris agreement” that he contends supports renewable energy to the exclusion of other energy sources. And he took aim at countries pledging to phase out coal use.
By Ellen Coleman—As an American of non-specific cultural identity, I look with envy at families with strong cultural tradition. I wonder who "my people” are. What family traditions will my children (now grown) want to pass on to their own children?  Their exposure has been such a mixed bag of “ritual”—making tamales for Thanksgiving, potstickers for family reunions, fried eggplant for Fourth of July.  What will be their choice of comfort music?  What kinds of homes will they make, what spiritual paths will they take?
Wind turbines need wind to produce energy. That message seems lost, not only on most small wind turbine owners, but also on many manufacturers and installers of said devices. One of the world’s largest manufacturers of small wind turbines, located in the USA (now bankrupt by the way, though their turbines are still sold), markets their flag-ship machine with a 12 meter (36 feet) tower. Their dealers are trained to tell you it will produce 60% of your electricity bill. If you are one of those that is convinced the earth is flat, this is the turbine for you!
Airflows can be used to run wind turbines. Modern utility-scale wind turbines range from around 600 kW to 5 MW of rated power, although turbines with rated output of 1.5–3 MW have become the most common for commercial use. The largest generator capacity of a single installed onshore wind turbine reached 7.5 MW in 2015. The power available from the wind is a function of the cube of the wind speed, so as wind speed increases, power output increases up to the maximum output for the particular turbine.[42] Areas where winds are stronger and more constant, such as offshore and high altitude sites, are preferred locations for wind farms. Typically full load hours of wind turbines vary between 16 and 57 percent annually, but might be higher in particularly favorable offshore sites.[43]

The conversion of sunlight into electricity is made possible with the special properties of semi-conducting materials. It can be harnessed through a range of ever-evolving technologies like solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants, and artificial photosynthesis.

A hybrid system combines (C)PV and CSP with one another or with other forms of generation such as diesel, wind and biogas. The combined form of generation may enable the system to modulate power output as a function of demand or at least reduce the fluctuating nature of solar power and the consumption of non renewable fuel. Hybrid systems are most often found on islands.
