AFRICA - Which country boasts the world's fastest growing clean energy investment? Germany? No. United States? Think again. Jumping from a few hundred million dollars to $5.7 billion, South Africa recorded last year the world's highest growth in renewable energy investment, according to the U.N. Environment Program (UNEP). The spectacular surge, led largely by investments in solar power projects, comes as South Africa moves to reduce its dependency on coal, which accounts for around 86% of its energy. To achieve that, the country has set the ambitious target of generating 18 gigawatts (GW) of clean energy by 2030. As a result, a series of investments have trickled into the country, including Google's first foray into Africa's solar power market. The internet giant, which has spent more than $1 billion in renewable energy projects in the United States and Europe in recent years, announced in late May its decision to back the Jasper Power Project, a 96 MW solar photovoltaic (PV) plant in Northern Cape, with a $12 million investment. "We only pursue investments that we believe make financial sense," said Rick Needham, Google's director of energy and sustainability. "South Africa's strong resources and supportive policies for renewable energy make it an attractive place to invest." Abundance of sun Once completed, Jasper is expected to be one of the biggest solar installations in the continent, capable of generating enough power for some 30,000 homes. It's no secret that Africa has plentiful sunshine, with many parts of the continent enjoying daily solar radiation of between 4 kWh and 6 kWh per square meter. But it's no secret, either, that Africa has the world's lowest electricity access rates, with more than half of its countries experiencing daily -- and costly -- power outages. Amid such conditions, experts say investments in large-scale solar power projects could transform a continent faced with fast-rising populations and increasing demand for energy to support its economic growth. "Six out of the 10 fastest economies in the world (over the past decade) were in Africa, and that requires much more energy, at a faster-growing pace than we've seen before," says Frank Wouters, deputy director-general of the International Renewable Energy Agency. Ambitious projects And some countries have already taken notice. While South Africa is clearly setting the pace, projects are being announced across the continent as more countries look to unlock their massive solar potential. In late April, Mauritania launched what's described as Africa's biggest solar PV plant so far, a 15 MW facility that is designed to account for 10% of the country's energy capacity, according to its developers. In early May, Morocco began the first phase of the construction of a 160 MW concentrated solar power technology plant near Ouarzazate as part of the country's efforts to produce 2,000 MW of solar energy by 2020.

The Race Is On For New Solar Power Technology The world demands new solar power technology in order to slow the effects of deadly global warming. Not only are activists, the common people and scientists calling for it, so are investors and technology companies. New solar power technology is coming into our lives all of the time in bits and pieces, which all add up to help put us on the path to renewable energy sources. A Brief Look At The Past The human race grows, matures and changes priorities. When the priorities change, that's where the money, resources and idea makers go. Perhaps first these were fire makers. Then they were boat-builders and sailors, farmers and herders. In the Industrial Revolution, the priorities went to bringing mass manufacturing to the masses. In the last twenty years, the home computer industry has been the primary focus of the world's financial and scientific attention. In fact, with the help of computers, we might never have known about global warming until it was way too late. PC Parallels There are many things about the solar power industry that are paralleling the personal computer industry. The first computers filled entire office buildings and did little more than crunch numbers. But now you can get a tiny cell phone with a screen just a tad bigger than a gnat's behind which can pretty much run every aspect of your entire life. What made computers smaller yet more powerful? Silicon chips. The new solar power technology is also using silicon for solar power panels. The cells in the panels are usually crystalline silicon cells. They are gradually getting smaller and rapidly becoming cheaper. There are also new ways to store these solar power panels. Tiny rows of solar power cells can run a retail store's calculator for an entire work day. Solar power cells can be laid onto a rollable mat and rolled out only when you need it, then rolled up and stored away for when you don't. Both of these devices are not science fiction. They are commonly in use today. New solar power technology is being integrated into our lives and homes to keep us from total future shock. With each use of the new solar power technology, we are that much closer to keeping this planet from going belly up. As more and more consumers demand renewable energy, there should be dizzying advances in the new solar power technology as there has been for personal computers.

Solar Panel Documentary - HISTORY MOVIES Solar panel refers to a panel made to take in the sunlight's rays as a source of power for creating electricity or home heating. A PV component is a packaged, connected assembly of normally 6 × 10 solar batteries. Solar PV panels make up the solar array of a photovoltaic system that produces as well as supplies solar electricity in business and also domestic applications. Each module is ranked by its DC outcome power under typical examination problems, as well as typically varies from 100 to 365 watts. The efficiency of a component identifies the location of a component given the exact same rated result-- an 8 % efficient 230 watt module will have two times the location of a 16 % reliable 230 watt component. There are a few photovoltaic panels offered that are exceeding 19 % performance. A single solar component could generate just a limited amount of power; many installations include several modules. A photovoltaic system normally includes a panel or an array of solar components, a solar inverter, and also sometimes a battery and/or solar tracker as well as interconnection wiring. The rate of solar power, together with batteries for storage, has actually remained to fall so that in several nations it is much cheaper compared to common fossil fuel electrical power from the grid (there is "grid parity"). For instance in 2015, an ordinary home in Europe or the United States can use around 3,000 kilowatt-hour (kWh) in power yearly. Twelve 280 watt solar PV components (each generating 250 kWh each year) would certainly generate at least 3,000 kWh each year, even in a cloudy country like the UK. An example market price would certainly have to do with ₤ 8,000 in the UK, $12,000 in the US, or EUR10,000 in the Eurozone in 2015, which is particular to continually drop, enabling irreversible power independence for each house. A lot of governments have feed-in toll systems that allow property owner to offer surplus energy back right into the grid, and also make a future revenue on their financial investment.

Solar RevolutionMichio Kaku: I believe in solar power, but there are problems that we have to face, and one of them is low efficiency. Michio Kaku: Some people think that the time is right for the solar revolution, that one day solar power will replace oil and we'll all live in a world that is clean and renewable. Well, not so fast. I believe in solar power. However, there are problems that we have to face, and one of them is low efficiency. The other one is lack of a storage facility like a battery. That's' the weak link. We simply don't have the efficiency of solar cells necessary to make it economical and competitive today, and the ability to store the energy for long periods of time when the sun is dark, when there are clouds and your solar panels don't work.So my point of view is this: I think in the coming decade, as oil prices start to rise and as the cost of wind and solar and renewables start to drop, the two currents will probably cross in maybe ten years. So in ten years it will be the marketplace which then begins to drive the whole thing forward because of the dropping cost of solar cells and rising efficiency and the rising price of oil. Now, why do I believe that oil prices will rise? Because of something called Hubbert's Peak. Hubbert was a Shell Oil engineer way back in the 1960s who predicted that we would hit the halfway point for the production of oil in the United States and after that the bell-shaped curve would curve the other way and we would become an importer of oil. Well, people laughed at him because they said that, "Well, wait a minute. We have Alaska. We have Texas. We have lots of oil fields, and so we're not going to hit the 50% point. America will always export oil." Well, wrong. Hubbert hit it right on the nose to within the year at which US oil supplies peaked and then it went to the other side of the bell-shaped curve. That's called Hubbert's Peak, when we hit the 50% point. Now we know that Hubbard was right and the next big question is, are we hitting Hubbert's Peak for world oil production? That is the $64,000 question. Many people that I've talked to, senior oil analysts, energy analysts, say that we are either at Hubbert's Peak or within ten years of hitting Hubbert's Peak. Now some people say, "Well that's stupid. We discover new oil deposits all the time. Look at Canada. We have tar sands of Canada, right?" Wrong. It turns out that we will always have oil. We will never run out of oil, except oil will become more expensive as we go down the other side of Hubbert's Peak. We would have to discover a new Saudi Arabia every five to ten years in order for this curve to simply go on forever. That's not going to happen. I don't care how many tar sands you're talking about in Canada. You're not going to create a new Saudi Arabia, which produces very clean, very cheap oil, oil that is prized by the oil companies because it is relatively less polluting and has tremendous amounts of profits associated with it. So we do know that oil prices will fluctuate because of politics, but on average it will start to rise because we will be hitting Hubbert's Peak. Meanwhile, solar power is going to become cheaper and in 10 years or so the two curves could actually cross, and in 20 years a new game changer arrives and that is fusion power. The Europeans are betting the store on the ITER fusion reactor to be built outside Cadarache, France in Southern France, and if we have the power of the sun on the earth then sea water could drive all our machines. So if this scenario plays out as I predict, it means that global warming could actually be a problem only for the next several decades as we enter the solar era and the fusion era. The problem is we have already lofted so much carbon dioxide into the atmosphere, and we will continue to do so for decades to come, that even before we enter the solar age and the fusion age we will have so much carbon dioxide in the atmosphere that we will really screw up the weather. But on a long-term basis I think that solar energy and fusion power will be the solution, the ultimate solution, for the greenhouse problem. Directed / Produced byJonathan Fowler & Elizabeth Rodd
