What is the future of solar energy?

What is the future of solar energy

I will summarize in two words the future of solar energy, VERY PROMISING.

Why is it explained below.

Solar energy has been used since ancient times. In Mesopotamia, for example we know that the priests lit the ceremonial fire with curved mirrors of polished gold in 2000 BC also said that Archimedes used mirrors to sink enemy ships diverting sunlight towards them.

In more recent times by the year 1930 they became popular in Japan solar collectors to heat water, but the low cost of fossil fuels at the time relegated quickly to solar energy.

It was not until 1973 when OPEC oil prices shot and solar energy back to the world map, since that day has been steady growth.

Today in the early 21st century, the energy future is more promising than ever.

A part of that oil prices have soared in recent years, thanks to predicted it will end in the next 20 years, the population has generally realizing that unless we take action on global warming, our grandchildren they will have a promising future.

Every day more discoveries to improve both efficiency rates of solar energy are made, and while the prices of fossil fuels will not stop rising, prices of solar energy will not let down.

So if you were looking for was whether the solar energy has a promising future , the answer is a resounding YES, solar energy has a promising future, and the more people we use the know and have a brighter future and faster.


Power consumption, reduce electricity bill

Less is consuming energy when you have knowledge of own consumption of light? According to the results of a test conducted in 100 households, significant differences are shown as a function of families continue or close the status of their consumption and stresses that the contribution of information is much more effective than one that is neutral, that has no comparison with the consumption of other households.

Can you reduce the consumption of light and perennial permanently without feeling back to the era of enlightenment through the candles? Are we able to identify the most voracious consumer devices are and are willing to change our habits? The consumption of light still seems something invisible in many households usually unaware of the sources of over consumption and poorly informed about the impact of their individual effort and contribution in this field.

Hikari, the first urban islet of positive energy in Lyon

Arranged along a nautical square, three new buildings are aligned in the center of the neighborhood, a piece of the city futuristic in prolonging the center of Lyon, built on old industrial remains.

The Hikari project began more than 10 years ago, and currently has 150 hectares, but due to double the surface. This ecobarrio of France must come to term at the end of 2020 and stop producing carbon despite the construction of one million square meters.

A new flow battery energy storage to help the solar and wind

A new flow battery energy storage to help the solar and wind

US scientists have developed a flow alkaline battery they hope will help alleviate the problem of storing energy from renewable energy sources such as wind and solar.

The battery performance is similar to current flow batteries, but uses non-toxic and cheap to store energy organic molecules. It is precisely the opposite of the existing batteries using metal solutions and they are usually quite expensive.

The energy storage batteries is vital to be able to better develop the energy that comes from sources such as solar or wind. By having batteries that provide sufficient capacity for the storage, energy companies will think more, every time you have to install a coal or gas in order to increase the electrical capacity of the grid.

A new flow battery energy storage to help the solar and wind

Batteries are a technology that provides an answer to this problem, but the market is with a variety of different products, as they are the Li-ion or cell lead-acid, which often involve a high cost and are unable to energy storage for extended periods.

The quality of the flow battery is that they have a better adaptation to the larger-scale energy storage. A battery type where recharge is provided by two chemical compounds dissolved in liquids contained within the system and separated by a membrane. Ion exchange occurs through the membrane, while the two media flow in its own respective space.

Following this loading process, the electrolytes can be stored in external tanks and, being the reversible current return back through the battery to be discharged later.

Michael Marshak, University of Colorado, is who leads the creative team of the new battery. They have found the right key to replace vanadium ions dissolved in sulfuric acid with cheaper components, abundant and non-toxic in the alkaline solution.

The equipment used commercially available organic molecules, such as Ferro cyanide and 2,6-diamino-anthraquinone, commonly used as food additives.

This will lead to different systems to be cheaper or more efficient over time.


Plant-e, or how to produce electricity through the plants

Plant-e, or how to produce electricity through the plants

A Dutch company intends to produce electricity by installing electrodes on the ground full of water where plants adapted to this type of growing medium. Although efficiency is still weak, this invention called Plant-and could transform the rice electricity production units.

A paddy day and night could produce enough electricity to power a remote village in Southeast Asia. This dream takes shape in the Netherlands, where scientists develop a system that generates power by plants growing in media saturated with water.

Founded in 2009, Plant-e markets and perfects an imagined by scientists at the University of Wageningen and patented in 2007.

This device produces electricity by little it is through plants growing in a water-saturated medium system, a large scale, such as in a rice field or a jar filled with water in the garden could be a quite effective method.

The technology relies on photosynthesis by the plant and used by which this occurs specifically organic matter. The surplus is removed on the ground by the roots, through which live microorganisms that feed and release electrons. Placing electrodes carbon close to the roots, these electrons can collect and generate power.


Samso, the Danish island of green energy

Samso, the Danish island of green energy

The Vikings, master of the winds, made this island in the middle of Denmark, a strategic place. They built a canal and a castle, from where they controlled the security of the island. Their descendants planted the masts of the wind on land and on water.

Samso today noted for its clear commitment to green energy. Its electricity comes from wind fighting on the island without a break, and heat from the sun, wood or straw. But still he wants to go further, eliminating fuel fossil their transport.

From the airport of Copenhagen, take the train to approach the coast, before embarking on one of the two daily ferries to the island 28 km long and 7 km at its narrowest part. Approaching the coast, sunset, ten perceive turbines placed on water. After eleven blades mills wind scattered over the low houses with thatched roofs.

This is how Samso has changed the course of their destiny. “It all started in 1997, has Michael Kristensen, a former carpenter converted to alternative energies. The Danish government started racing five islands, with a roadmap: to become self-sufficient in ten years, thanks to a 100% renewable resources. Our project won”.


France decreed that new roofs should be covered by plants or solar panels

France decreed that new roofs should be covered by plants or solar panels

All new buildings in commercial areas around the country must meet a new legislation for the environment, and this is that they should be partially covered by plants or solar panels under a law that was passed last Thursday.

Green roofs cause an insulating effect to help reduce the amount of energy required to heat a building in winter and cool in summer.

They also retain rainwater which helps that collect in their leaves, except that also promotes biodiversity and gives the birds a place to build their nests in the urban jungle.

The law passed by parliament has been more limited than initially wanted activists in environmental wanting the whole entire surface of the new constructed buildings cover. The Socialist government activists convinced that the only limit is made in the buildings of shopping areas.

The other option they have planted new buildings in commercial areas is that instead of placing plants, can choose to install solar panels to produce electricity. And what would these green roofs are quite popular in other countries like Germany and Australia , and even in Toronto, Canada City, where a new law enacted in 2009 that required in new buildings for residential and industrial purposes.

Some green roofs that give another color to the gray that dominates the city and that takes part of that same color of life that makes both these façades lack coloring horizon lines and those that are lost among skyscrapers and tall buildings. A decree which we hope will spread over countries like our own. Greener Madrid is needed. We expect changes.
