Solar energy in Morocco is transforming the renewable energy scene. One of the world’s biggest solar power plants is situated in Morocco.

Jaouad Ait Rebah changes a lot of people’s lives in the High Atlas Mountains – by bringing light where there is darkness. The Moroccan entrepreneur installs solar panels in the area’s picturesque, but remote villages. For the high-altitude residents, the difference is like that of night and day.

The beautiful scenery is mostly lost on those living there. They live in extreme poverty. Many young people have left due to the lack of jobs. Now, however, the solar panels are modernizing the villages.
Jaouad Ait Rebah and his work symbolize the energy revolution that has been sweeping across Morocco in recent years. The country is leading the change to renewables in Africa, as is evident in Jaouad’s native Ouarzazate.

The city is home to one of the biggest solar power plants in the world, comprising almost one million parabolic mirrors. King Mohammed VI. is investing billion in the facility, which provides electricity to two million people. By 2040, Morocco aims to generate almost half of its power from renewable energy sources.

Our team accompanied Jaouad Ait Rebah as he went about his challenging and laborious work, marveling at the scale of the enormous solar facilities, and asks to what degree King Mohammed VI.’s ambitious projects are actually trickling down to the little people.

Not too far from Earth is a giant space rock that has silently played host to just twelve people in its entire history. What would happen if we put our cosmic satellite to work by covering it with solar panels?

What would it take to build an enormous power plant on the Moon? How big would this facility be? And how much time would it take to finish this mega-construction?

Solar Panel System, Prices In The Philippines.

We visit an onsite Solar Panel System installation in the Philippines, and an engineer talks us through the system. We also discuss return of investment (4 Years), available warranties, and the costs of a typical system. The store where these products are available is located at TPE Building, Banilad, Unit 105, Governor M. Cuenco Avenue. Cebu City 6000, Philippines. Tel: (+63) 32 239 6591

Is green energy, particularly wind and solar energy, the solution to our climate and energy problems? Or should we be relying on things like natural gas, nuclear energy, and even coal for our energy needs and environmental obligations? Alex Epstein of the Center for Industrial Progress explains.

Script:

Are wind and solar power the answer to our energy needs? There’s a lot of sun and a lot of wind. They’re free. They’re clean. No CO2 emissions. So, what’s the problem?

Why do solar and wind combined provide less than 2% of the world’s energy?

To answer these questions, we need to understand what makes energy, or anything else for that matter, cheap and plentiful.

For something to be cheap and plentiful, every part of the process to produce it, including every input that goes into it, must be cheap and plentiful.

Yes, the sun is free. Yes, wind is free. But the process of turning sunlight and wind into useable energy on a mass scale is far from free. In fact, compared to the other sources of energy — fossil fuels, nuclear power, and hydroelectric power, solar and wind power are very expensive.

The basic problem is that sunlight and wind as energy sources are both weak (the more technical term is dilute) and unreliable (the more technical term is intermittent). It takes a lot of resources to collect and concentrate them, and even more resources to make them available on-demand. These are called the diluteness problem and the intermittency problem.

The diluteness problem is that, unlike coal or oil, the sun and the wind don’t deliver concentrated energy — which means you need a lot of additional materials to produce a unit of energy.

For solar power, such materials can include highly purified silicon, phosphorus, boron, and a dozen other complex compounds like titanium dioxide. All these materials have to be mined, refined and/or manufactured in order to make solar panels. Those industrial processes take a lot of energy.

For wind, needed materials include high-performance compounds for turbine blades and the rare-earth metal neodymium for lightweight, specialty magnets, as well as the steel and concrete necessary to build structures — thousands of them — as tall as skyscrapers.

And as big a problem as diluteness is, it’s nothing compared to the intermittency problem. This isn’t exactly a news flash, but the sun doesn’t shine all the time. And the wind doesn’t blow all the time. The only way for solar and wind to be truly useful would be if we could store them so that they would be available when we needed them. You can store oil in a tank. Where do you store solar or wind energy? No such mass-storage system exists. Which is why, in the entire world, there is not one real or proposed independent, freestanding solar or wind power plant. All of them require backup. And guess what the go-to back-up is: fossil fuel.

Here’s what solar and wind electricity look like in Germany, which is the world’s leader in “renewables”. The word erratic leaps to mind. Wind is constantly varying, sometimes disappearing completely. And solar produces little in the winter months when Germany most needs energy.

You can find “energy saving” devices on the market that are little more than a capacitor that is wired across the ac lines. In this demonstration shot at Eaton Corp.’s Power Systems Experience Center, Dan Carnovale explains how measurements made with these devices installed can give misleading readings that imply energy savings where none really exist. Most often, unsuspecting victims get fooled by looking at read-outs of watts instead of a read-out of volt-amps.
