GREEN ENERGY for a Developing World -1 -
Purchasing green energy through the electrical grid :
In several countries with common carrier arrangements, electricity retailing arrangements make it possible for consumers to purchase green electricity (renewable electricity) from either their utility or a green power provider.
http://WERI-events.org
When energy is purchased from the electricity network, the power reaching the consumer will not necessarily be generated from green energy sources. The local utility company, electric company, or state power pool buys their electricity from electricity producers who may be generating from fossil fuel, nuclear or renewable energy sources. In many countries green energy currently provides a very small amount of electricity, generally contributing less than 2 to 5% to the overall pool. In some U.S. states, local governments have formed regional power purchasing pools using “Community Choice Aggregation” and “Solar Bonds” to achieve a 51% renewable mix or higher, such as in the City of San Francisco.
By participating in a green energy program a consumer may be having an effect on the energy sources used and ultimately might be helping to promote and expand the use of green energy. They are also making a statement to policy makers that they are willing to pay a price premium to support renewable energy. Green energy consumers either obligate the utility companies to increase the amount of green energy that they purchase from the pool (so decreasing the amount of non-green energy they purchase), or directly fund the green energy through a green power provider. If insufficient green energy sources are available, the utility must develop new ones or contract with a third party energy supplier to provide green energy, causing more to be built. However, there is no way the consumer can check whether or not the electricity bought is “green” or otherwise.
In some countries such as the Netherlands, electricity companies guarantee to buy an equal amount of ‘green power’ as is being used by their green power customers. The Dutch government exempts green power from pollution taxes, which means green power is hardly any more expensive than other power.
In the United States, one of the main problems with purchasing green energy through the electrical grid is the current centralized infrastructure that supplies the consumers electricity. This infrastructure has lead to increasingly frequent brown outs and black outs, high CO2 emissions, higher energy costs, and power quality issues . An additional $450 billion will be invested to expand this fledgling system over the next 20 years to meet increasing demand . In addition, this centralized system is now being further overtaxed with the incorporation of renewable energies such as wind, solar, and geothermal energies. Renewable resources, due to the amount of space they require, are often located in remote areas where there is a lower energy demand. The current infrastructure would make transporting this energy to high demand areas, such as urban centers, highly inefficient and in some cases impossible. In addition, despite the amount of renewable energy produced or the economic viability of such technologies only about 20 percent will be able to be incorporated into the grid. To have a more sustainable energy profile, the United States must move towards implementing changes to the electrical grid that will accommodate a mixed-fuel economy [75].
However, several initiatives are being proposed to mitigate these distribution problems. First and foremost, the most effective way to reduce USAs CO2 emissions and slow global warming is through conservation efforts. Opponents of the current US electrical grid have also advocated for decentralizing the grid. This system would increase efficiency by reducing the amount of energy lost in transmission. It would also be economically viable as it would reduce the amount of power lines that will need to be constructed in the future to keep up with demand. Merging heat and power in this system would create added benefits and help to increase its efficiency by up to 80-90%. This is a significant increase from the current fossil fuel plants which only have an efficiency of 34% .

A more recent concept for improving our electrical grid is to beam microwaves from Earth-orbiting satellites or the moon to directly when and where there is demand. The power would be generated from solar energy captured on the lunar surface In this system, the receivers would be broad, translucent tent-like structures that would receive microwaves and convert them to electricity. NASA said in 2000 that the technology was worth pursuing but it is still too soon to say if the technology will be cost-effective

Portugal, home of the biggest solar plant in the world
In today’s era, when Global warming is on its high, Portugal, a small country in Southern Europe, is taking a bold stake in renewable energies. Thanks to the “great Portuguese sun”, Portugal is now home of the world’s biggest and most powerful solar energy plant. The 11-megawatt plant (located near Serpa, a small town in the country’s southern province of Alentejo) with its 52,000 photovoltaic modules, which producing 20 gigawatt hours of power each year delivers enough electricity to power 8,000 homes, is a part of Portugal’s plan to produce 45 % of its electricity from renewable energy sources. Apart from solar energy, Portugal is also turning to wind and wave power to reduce its oil imports and meet its international commitments to reduce carbon dioxide emissions, having in this matters one of the most ambitious targets in the world.
If God has given to the Portuguese no oil, they will have to suffice only with their wind, their sun and their waves — and it seems that with more than 305 days of sun per year, and 1250 km of Atlantic coastline they are just about to make it.

This is not “How to make PV Solar Cells”.
It is possible to home-make Copper Oxide and other kinds of materials but that is a whole nother story which I may do in the future.
I may be a little bit ambitious to try to show you how I made PV Solarpanels out of various types of cells I collected and how and where I obtained them rather inexpensively
