Renewable Energy: Invitation to PF members

[Toramana]

My reason for promoting and supporting renewable energy is that it is distributed more uniformly in the world unlike the conventional energy which is concentrated in a few countries. Moreover, it is environment friendly and by adopting it, poor countries can raise the standard of life of their people to a good degree.

This field also have prospects for research and market expansion.

I invite all members to support UN renewable energy efforts and sensitize your respective societies about the benefits of renewable energy.

PV off-grid in developing countries is more than poverty mitigation – it’s sound business sense

I favour renewable energy (solar, wind, tidal, biogas,etc.) for the following reasons.

1. It is more evenly distributed around the world unlike conventional hydrocarbon energy which is concentrated in some countries. This is especially the case for solar and wind energy.

2. It is environmentally clean.

3. It can arrest the deforestration going on in our areas for energy needs.

4. It can lead to rapid electrification of villages and homes because no extensive large scale infrastructure is needed. For example, a solar panel can be installed on the roof of house to electrify the house.

5. It can lead to the rise of living standards by providing access to energy sources and the amenities associated with the use of energy.

6. It is renewable non-exhaustible unlike the conventional hydro-carbon energy which is exhaustible.

Renawable energy can certainly help Pashtuns.

It would be more useful and simple to understand if you explain its cost and its output per item separately.
If its cheaper than the conventional sources of energies then why would we not to have it ?
Thanks

Economics

Despite the overwhelming availability of solar power, little was installed, compared to other power generation, prior to 2012, due to the high installation cost. This cost has declined as more systems have been installed, and has followed a typical learning curve.

Photovoltaic systems use no fuel and modules typically last 25 to 40 years. The cost of installation is almost the only cost, as there is very little maintenance required. Installation cost is measured in $/watt or €/watt. The electricity generated is sold for ¢/kWh. 1 watt of installed photovoltaics generates roughly 1 to 2 kWh/year, as a result of the local insolation. The product of the local cost of electricity and the insolation determines the break even point for solar power. The International Conference on Solar Photovoltaic Investments, organized by EPIA, has estimated that PV systems will pay back their investors in 8 to 12 years.[54] As a result, since 2006 it has been economical for investors to install photovoltaics for free in return for a long term power purchase agreement. Fifty percent of commercial systems were installed in this manner in 2007 and over 90% by 2009.[55]

As of 2011, the cost of PV has fallen well below that of nuclear power and is set to fall further. The average retail price of solar cells as monitored by the Solarbuzz group fell from $3.50/watt to $2.43/watt over the course of 2011, and a decline to prices below $2.00/watt seems inevitable:[56]



Economic photovoltaic capacity vs installation cost, in the United States.
A U.S. study of the amount of economic installations agrees closely with the actual installations.

For large-scale installations, prices below $1.00/watt are now common. In some locations, PV has reached grid parity, the cost at which it is competitive with coal or gas-fired generation. More generally, it is now evident that, given a carbon price of $50/ton, which would raise the price of coal-fired power by 5c/kWh, solar PV will be cost-competitive in most locations. The declining price of PV has been reflected in rapidly growing installations, totalling about 23 GW in 2011. Although some consolidation is likely in 2012, as firms try to restore profitability, strong growth seems likely to continue for the rest of the decade. Already, by one estimate, total investment in renewables for 2011 exceeded investment in carbon-based electricity generation.[56]

Additionally, governments have created various financial incentives to encourage the use of solar power, such as feed-in tariff programs. Also, Renewable portfolio standards impose a government mandate that utilities generate or acquire a certain percentage of renewable power regardless of increased energy procurement costs. In most states, RPS goals can be achieved by any combination of solar, wind, biomass, landfill gas, ocean, geothermal, municipal solid waste, hydroelectric, hydrogen, or fuel cell technologies.[57]

Shi Zhengrong has said that, as of 2012, unsubsidised solar power is already competitive with fossil fuels in India, Hawaii, Italy and Spain. He said "We are at a tipping point. No longer are renewable power sources like solar and wind a luxury of the rich. They are now starting to compete in the real world without subsidies". "Solar power will be able to compete without subsidies against conventional power sources in half the world by 2015"
