The sun has powered organic life on planet Earth since before human beings even existed. And we’ve attempted to harness the power of solar energy since the very beginning. Although early uses for solar energy revolved around methods to ignite a fire, the 20th century introduced mankind to the potential of solar electricity. In this video, we’ll explore the technology behind a solar power system and how it converts the sun’s rays into clean, renewable energy while caring for Mother Earth. It’s an energy strategy that proves working with nature can yield greater results than trying to fight against it. You can visit our website for more information today!

Renewable Energy 101
Question: What’s the most abundant energy source in our solar system? Here’s a hint, it’s 1 million times bigger than the Earth and without it our planet would be a dark, cold rock floating in space. You guessed it: the incredible, brilliant sun.
The Earth gets more energy from this ball of fire and gas in one day than the whole world’s population uses in an entire year. Every living thing depends on the sun for its existence, from tiny microbes deep in the ocean to plants, animals and people.
Humans have been tinkering with solar energy since the dawn of time. Ancient civilizations used glass and mirrors to light fires, but it wasn’t until the 1950s that technology was developed to convert the sun’s energy into electricity using photovoltaic cells. Today, solar technology is more efficient and less expensive and is used all around the globe to create electricity, heat water, cook food and even power vehicles.
So how do solar panels usually work? When the sun hits a solar panel, material inside (usually silicon) absorbs the energy. This causes the electrons and its atoms to get very excited and start dancing around. The atoms then get hot and shed the electrons, which travel out of the panel through copper wiring and — ZAP! — we have electricity! A control device called an inverter changes this electricity from direct current to the alternating current we use. The electricity then passes from breaker boxes to outlets and into electrical items like a computer and lights. Whatever you don’t use can go back into the grid to be used by someone else.
So there you have it — the amazing power of the sun. Some people see a future where most of our energy can come from this pollution-free and renewable resource, and that’s a sunny outlook that will make the whole world smile!

8. SOUNDBITE: (English) Robert Dane, inventor of the Solar Sailor:
“The idea came from the way that insects evolved wings in the sense that they initially grew little these buds to use as solar collectors and then eventually they evolved into wings and they used them to fly so we thought well boats can evolve wings and use them as solar collectors and use them to sail, which of course is a lot easier than flying.”
9. Mid shot solar powered boat, zoom in on wings.
10. Tilt down on wings
11. Wings on vessel turning
12. SOUNDBITE: (English) Robert Dane, inventor of the Solar Sailor:
“It’s like the hybrid car in the sense that it combines electric motors and in this vessel a generator running on LPG (liquid petroleum gas) gas, but it could run on anything and so fundamentally it’s an all electric boat that’s running on batteries and the batteries are powered by the sun, and also by a generator and also by being plugged in.”
13. Traditional motor boat sailing along the water
14. Former Australian Prime Minister Bob Hawke walking on board the solar powered boat
15. SOUNDBITE: (English) Bob Hawke, former Australian prime minister:
“Basically at the wharf there are zero emissions and all the available evidence says that this is the most hazardous part of ferry tug operations. They come into the wharf and they’re letting out all these hazardous fumes, well we have zero emissions at the wharf.”

25. SOUNDBITE: (English) Anthony Haworth, CEO of Captain Cooke Cruises:
“People who take this boat as a charter boat, take it not only because it’s a comfortable little ship but because she’s now an environmentally friendly boat that’s really good for the environment they feel good about doing it and it’s great to be able to operate something like this.”
26. Solar boat on the water
27. SOUNDBITE: (English) Paul Stratis, Solar Sailor captain:
“We’re able to tell the sails where the sun is, once we’ve done that the sun, and the sails will work automatically and it will adjust and give us the energy to make the vessel move.”

31. SOUNDBITE: (English) Paul Stratis, Solar Sailor captain:
“It can’t compare with a fuel or a diesel engine, obviously because a diesel engine is much bigger. But the concept of this one is that we’re able to use very little motors and use the sun and produce enough power to get the boat to move up to about ten knots.”

LEAD IN:
Wings might be something we’re more used to seeing on a plane, but a boat sailing around Sydney Harbour has wings of its own.
Fitted with solar panels that provide it with a sustainable, environmentally friendly energy source, its inventor believes it will be the boat of the future.
STORYLINE:
In Sydney’s Darling Harbour it’s a case of the past meets the future.
The ‘Solar Sailor’ is the brainchild of a small town doctor Robert Dane.
Dane says that the boat operates similar to a hybrid car.

What are the environmental benefits of solar energy?
Solar isn’t just great for your wallet, it’s also an environmentally-friendly energy choice. Here are some of the many environmental benefits you’ll enjoy if you switch to solar energy.
To start, solar is a renewable resource, which means it is abundant and replenishes quickly. Compare this to fossil fuels which exist in a limited supply and replenish very slowly. Here’s a fun fact: enough solar energy hits the earth each hour to power the entire world for an entire year.
Additionally, harnessing solar energy is a low-impact process compared to harvesting fossil fuels. Drilling for oil involves digging deep into the earth and interfering with our natural environment. On the other hand, setting up a new solar panel installation has a much lower environmental impact. This is because – unlike traditional power plants – solar is commonly installed on existing structures or otherwise unusable plots of land – such as rooftops, over parking lots, or on landfills.
Solar energy is also an emission-free, clean source of power. Generating energy with fossil fuels increases carbon dioxide emissions in the atmosphere, which contributes to global climate change. Using fossil fuels also releases additional pollutants and toxins into the atmosphere and water supply. After you install solar panels, you’ll use less electricity generated from coal, oil and gas – this lowers your carbon footprint and helps protect the environment.
When you compare options for solar on the EnergySage Marketplace, your quotes will show you how much pollution you’ll personally offset by making the switch to solar power.

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.

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.
