Microgeneration

In the United States, Microgeneration had its roots in the 1973 oil crisis and the Yom Kippur War which prompted innovation.{{Cite web |last=Frommer |first=Fred |title=How the 1970s Energy Crisis Drove Innovation |url=https://www.history.com/news/energy-crisis-1970s-innovation |access-date=2022-10-25 |website=HISTORY |date=17 October 2022 |language=en}}

On June 20, 1979, 32 solar panels were installed at the White House.{{Cite web |last=Biello |first=David |title=Where Did the Carter White House's Solar Panels Go? |url=https://www.scientificamerican.com/article/carter-white-house-solar-panel-array/ |access-date=2022-10-25 |website=Scientific American |language=en}} The solar cells were dismantled 7 years later during the Reagan administration.{{cite web | title=White House Solar Panel | website=National Museum of American History | url=https://americanhistory.si.edu/collections/search/object/nmah_1356218 | access-date=2022-10-25}}

In addition to the electricity production plant (e.g. wind turbine and solar panel), infrastructure for energy storage and power conversion and a hook-up to the regular electricity grid is usually needed and/or foreseen. Although a hookup to the regular electricity grid is not essential, it helps to decrease costs by allowing financial recompensation schemes. In the developing world however, the start-up cost for this equipment is generally too high, thus leaving no choice but to opt for alternative set-ups.{{Cite web |url=http://practicalaction.org/practicalanswers/product_info.php?cPath=21&products_id=269 |title=Practical Action - Energy for rural communities |access-date=2008-03-16 |archive-url=https://web.archive.org/web/20160308175301/http://practicalaction.org/practicalanswers/product_info.php?cpath=21&products_id=269 |archive-date=2016-03-08 |url-status=dead }}

The whole of the equipment required to set up a working system and for an off-the-grid generation and/or a hook up to the electricity grid herefore is termed a balance of system{{cite web|url=http://www.eere.energy.gov/consumer/your_home/electricity/index.cfm/mytopic=10620|title=Office of Energy Efficiency & Renewable Energy - Department of Energy|access-date=2008-02-21|archive-date=2008-06-22|archive-url=https://web.archive.org/web/20080622003954/http://www.eere.energy.gov/consumer/your_home/electricity/index.cfm/mytopic=10620|url-status=live}} and is composed of the following parts with PV-systems:

A major issue with off-grid solar and wind systems is that the power is often needed when the sun is not shining or when the wind is calm, this is generally not required for purely grid-connected systems:

• a series of deep cycle, stationary or sealed maintenance free batteries (the most common solution){{Cite web |url=http://practicalaction.org/practicalanswers/product_info.php?cPath=21&products_id=269 |title=Practical Action - Energy for rural communities (includes short description batteries) |access-date=2008-03-16 |archive-url=https://web.archive.org/web/20160308175301/http://practicalaction.org/practicalanswers/product_info.php?cpath=21&products_id=269 |archive-date=2016-03-08 |url-status=dead }}

or other means of energy storage (e.g. hydrogen fuel cells, Flywheel energy storage, pumped-storage hydroelectricity, compressed air tanks, ...){{cite web|url=http://www.thesietch.org/projects/Hydrogenmaker/index.htm|title=Welcome to The Sietch - Projects Make Your Own Hydrogen|access-date=2008-03-15|archive-date=2017-09-11|archive-url=https://web.archive.org/web/20170911041623/http://www.thesietch.org/projects/Hydrogenmaker/index.htm|url-status=live}}

• a charge controller for charging the batteries or other energy storage

For converting DC battery power into AC as required for many appliances, or for feeding excess power into a commercial power grid:

• an inverter or grid-interactive inverter. The whole is also sometimes referred to as "power conditioning equipment"

• Groundings, transfer switches or isolator switches and surge protectors. The whole is also sometimes referred to as "safety equipment"

Usually, in microgeneration for homes in the developing world, prefabricated house-wiring systems (as wiring harnesses or prefabricated distribution units) are used instead.{{Cite web |url=http://practicalaction.org/practicalanswers/product_info.php?cPath=21&products_id=269 |title=Mentioning of prefabricated house-wiring and its systems |access-date=2008-03-16 |archive-url=https://web.archive.org/web/20160308175301/http://practicalaction.org/practicalanswers/product_info.php?cpath=21&products_id=269 |archive-date=2016-03-08 |url-status=dead }} Simplified house-wiring boxes and cables, known as wiring harnesses, can simply be bought and mounted into the building without requiring much knowledge about the wiring itself. As such, even people without technical expertise are able to install them. They are also comparatively cheap and offer safety advantages.{{Cite web |url=http://practicalaction.org/practicalanswers/product_info.php?cPath=21&products_id=269 |title=Benefits of wiring harnasses |access-date=2008-03-16 |archive-url=https://web.archive.org/web/20160308175301/http://practicalaction.org/practicalanswers/product_info.php?cpath=21&products_id=269 |archive-date=2016-03-08 |url-status=dead }}

• battery meters (for charging rate and voltage), and meters for power consumption and electricity provision to the regular power grid

• a manual disconnect switch
• foundation for the tower
• grounding system
• shutoff and/or dummy-load devices for use in high wind when power generated exceeds current needs and storage system capacity.

A new wind energy technology is being developed that converts energy from wind energy vibrations to electricity. This energy, called Vibro-Wind technology, can use winds of less strength than normal wind turbines, and can be placed in almost any location.

A prototype consisted of a panel mounted with oscillators made out of pieces of foam. The conversion from mechanical to electrical energy is done using a piezoelectric transducer, a device made of a ceramic or polymer that emits electrons when stressed. The building of this prototype was led by Francis Moon, professor of mechanical and aerospace engineering at Cornell University. Moon's work in Vibro-Wind Technology was funded by the Atkinson Center for a Sustainable Future at Cornell.{{cite news|last=Ju|first=Anne|title=Students harness vibrations from wind for electricity|url=http://www.news.cornell.edu/stories/May10/VibroWind.html|access-date=20 July 2011|newspaper=Cornell Chronicle|date=25 May 2010|archive-date=5 October 2012|archive-url=https://web.archive.org/web/20121005150921/http://www.news.cornell.edu/stories/May10/VibroWind.html|url-status=live}} Vibro-wind power is not yet commercially viable and in early development stages. Significant progress will be needed to commercialize this early stage venture.

Several microgeneration set-ups are possible. These are:

• Off-the-grid set-ups which include:
• Off-the grid set-ups without energy storage (e.g., battery, ...)
• Off-the grid set-ups with energy storage (e.g., battery, ...)
• Battery charging stations{{Cite web |url=http://practicalaction.org/practicalanswers/product_info.php?cPath=21&products_id=269 |title=Battery charging stations explained |access-date=2008-03-16 |archive-url=https://web.archive.org/web/20160308175301/http://practicalaction.org/practicalanswers/product_info.php?cpath=21&products_id=269 |archive-date=2016-03-08 |url-status=dead }}
• Grid-connected set-ups which include:
• Grid connected with backup to power critical loads
• Grid-connected set-ups without financial recompensation scheme
• Grid-connected set-ups with net metering
• Grid connected set-ups with net purchase and sale{{cite web|url=http://www.eere.energy.gov/consumer/your_home/electricity/index.cfm/mytopic=10600|title=Office of Energy Efficiency & Renewable Energy - Department of Energy|access-date=2008-03-17|archive-date=2008-06-22|archive-url=https://web.archive.org/web/20080622010101/http://www.eere.energy.gov/consumer/your_home/electricity/index.cfm/mytopic%3D10600|url-status=live}}

All set-ups mentioned can work either on a single power plant or a combination of power plants (in which case it is called a hybrid power system).

For safety, grid-connected set-ups must automatically switch off or enter an "anti-islanding mode" when there is a failure of the mains power supply. For more about this, see the article on the condition of islanding.

Depending on the set-up chosen (financial recompensation scheme, power plant, extra equipment), prices may vary. According to Practical Action, microgeneration at home which uses the latest in cost saving-technology (wiring harnesses, ready boards, cheap DIY-power plants, e.g. DIY wind turbines) the household expenditure can be extremely low-cost. In fact, Practical Action mentions that many households in farming communities in the developing world spend less than $1 on electricity per month.{{Cite web |url=http://practicalaction.org/practicalanswers/product_info.php?cPath=21&products_id=269 |title=Households reducing their energy expenditures to $1 a month using renewable microgeneration |access-date=2008-03-16 |archive-url=https://web.archive.org/web/20160308175301/http://practicalaction.org/practicalanswers/product_info.php?cpath=21&products_id=269 |archive-date=2016-03-08 |url-status=dead }} However, if matters are handled less economically (using more commercial systems/approaches), costs will be dramatically higher. In most cases however, financial advantage will still be done using microgeneration on renewable power plants; often in the range of 50-90%{{cite web|url=http://www.eere.energy.gov/consumer/your_home/electricity/index.cfm/mytopic=10880|title=Office of Energy Efficiency & Renewable Energy - Department of Energy|access-date=2008-03-17|archive-date=2008-08-29|archive-url=https://web.archive.org/web/20080829021113/http://www.eere.energy.gov/consumer/your_home/electricity/index.cfm/mytopic=10880|url-status=live}} as local production has no electricity transportation losses on long distance power lines or energy losses from the Joule effect in transformers where in general 8-15% of the energy is lost.{{cite web|url=http://blog.schneider-electric.com/energy-management-energy-efficiency/2013/03/25/how-big-are-power-line-losses/|title=How big are Power line losses? - Schneider Electric Blog|date=25 March 2013|access-date=28 November 2013|archive-date=7 May 2015|archive-url=https://web.archive.org/web/20150507033237/http://blog.schneider-electric.com/energy-management-energy-efficiency/2013/03/25/how-big-are-power-line-losses/|url-status=live}}

In the UK, the government offers both grants and feedback payments to help businesses, communities and private homes to install these technologies. Businesses can write the full cost of installation off against taxable profits whilst homeowners receive a flat-rate grant or payments per kW h of electricity generated and paid back into the national grid. Community organizations can also receive up to £200,000 in grant funding.[http://www.microgeneration.com/grants-and-funding UK Grant Funding information] {{webarchive|url=https://web.archive.org/web/20091109225234/http://www.microgeneration.com/grants-and-funding |date=2009-11-09 }}

In the UK, the Microgeneration Certification Scheme provides approval for Microgeneration Installers and Products which is a mandatory requirement of funding schemes such as the Feed in Tariffs and Renewable Heat Incentive.

Grid parity (or socket parity) occurs when an alternative energy source can generate electricity at a levelized cost of energy (LCOE) that is less than or equal to the price of purchasing power from the electricity grid. Reaching grid parity is considered to be the point at which an energy source becomes a contender for widespread development without subsidies or government support. It is widely believed that a wholesale shift in a generation to these forms of energy will take place when they reach grid parity.

Grid parity has been reached in some locations with on-shore wind power around 2000, and with solar power it was achieved for the first time in Spain in 2013.{{cite web|url=https://www.forbes.com/sites/peterdetwiler/2012/12/26/solar-grid-parity-comes-to-spain/|title=Solar Grid Parity Comes to Spain|first=Peter|last=Kelly-Detwiler|website=Forbes |access-date=2017-09-05|archive-date=2017-09-12|archive-url=https://web.archive.org/web/20170912184934/https://www.forbes.com/sites/peterdetwiler/2012/12/26/solar-grid-parity-comes-to-spain/|url-status=live}}{{cite web|url=http://oilprice.com/Latest-Energy-News/World-News/Spain-Achieves-Grid-Parity-for-Solar-Power.html|title=Spain Achieves Grid Parity for Solar Power - OilPrice.com|access-date=2013-11-28|archive-date=2016-11-12|archive-url=https://web.archive.org/web/20161112050151/http://oilprice.com/Latest-Energy-News/World-News/Spain-Achieves-Grid-Parity-for-Solar-Power.html|url-status=live}}{{cite web|url=http://www.conergy.com/desktopdefault.aspx/tabid-136/281_read-831/ |title=Conergy wins Intersolar Award for innovative grid parity project in Spain - Conergy Worldwide |access-date=2013-11-28 |url-status=dead |archive-url=https://web.archive.org/web/20131225065134/http://www.conergy.com/desktopdefault.aspx/tabid-136/281_read-831/ |archive-date=2013-12-25 }}

Most forms of microgeneration can dynamically balance the supply and demand for electric power, by producing more power during periods of high demand and high grid prices, and less power during periods of low demand and low grid prices. This "hybridized grid" allows both microgeneration systems and large power plants to operate with greater energy efficiency and cost effectiveness than either could alone.

Microgeneration can be integrated as part of a self-sufficient house and is typically complemented with other technologies such as domestic food production systems (permaculture and agroecosystem), rainwater harvesting, composting toilets or even complete greywater treatment systems. Domestic microgeneration technologies include: photovoltaic solar systems, small-scale wind turbines, micro combined heat and power installations, biodiesel and biogas.

Private generation decentralizes the generation of electricity and may also centralize the pooling of surplus energy. While they have to be purchased, solar shingles and panels are both available. Capital cost is high, but saves in the long run. With appropriate power conversion, solar PV panels can run the same electric appliances as electricity from other sources.Fritsch, Al, and Paul Gallimore. Healing Appalachia: Sustainable Living Through Appropriate Technology. Lexington, KY. The UP of Kentucky, 2007.

Passive solar water heating is another effective method of utilizing solar power. The simplest method is the solar (or a black plastic) bag. Set between {{convert|5|and|20|L|usgal|sigfig=1}} out in the sun and allow to heat. Perfect for a quick warm shower.{{cite web|url=http://www.motherearthnews.com/Green-Homes/2007-10-01/Build-Your-Own-Solar-Water-Heater.aspx|title=How to Build a Passive Solar Water Heater|access-date=2008-12-03|archive-date=2008-10-15|archive-url=https://web.archive.org/web/20081015021510/http://www.motherearthnews.com/Green-Homes/2007-10-01/Build-Your-Own-Solar-Water-Heater.aspx|url-status=live}}

The ‘breadbox’ heater can be constructed easily with recycled materials and basic building experience. Consisting of a single or array of black tanks mounted inside a sturdy box insulated on the bottom and sides. The lid, either horizontal or angled to catch the most sun, should be well sealed and of a transparent glazing material (glass, fiberglass, or high temp resistant molded plastic). Cold water enters the tank near the bottom, heats and rises to the top where it is piped back into the home.

Ground source heat pumps exploit stable ground temperatures by benefiting from the thermal energy storage capacity of the ground. Typically ground source heat pumps have a high initial cost and are difficult to install by the average homeowner. They use electric motors to transfer heat from the ground with a high level of efficiency. The electricity may come from renewable sources or from external non-renewable sources.

Biodiesel is an alternative fuel that can power diesel engines and can be used for domestic heating. Numerous forms of biomass, including soybeans, peanuts, and algae (which has the highest yield), can be used to make biodiesel. Recycled vegetable oil (from restaurants) can also be converted into biodiesel.

Biogas is another alternative fuel, created from the waste product of animals. Though less practical for most homes, a farm environment provides a perfect place to implement the process. By mixing the waste and water in a tank with space left for air, methane produces naturally in the airspace. This methane can be piped out and burned, and used for a cookfire.

Policymakers were accustomed to an energy system based on big, centralised projects like nuclear or gas-fired power stations. A change of mindsets and incentives are bringing microgeneration into the mainstream. Planning regulations may also require streamlining to facilitate the retrofitting of microgenerating facilities onto homes and buildings.

Most of developed countries, including Canada (Alberta), the United Kingdom, Germany, Poland, Israel[http://www.israel-electric.co.il/Static/WorkFolder/HomeClients/pv-hahachlata-hamelea.pdf State of Israel Public Utilities Authority Decision #216 (Hebrew)] {{webarchive|url=https://web.archive.org/web/20090824063407/http://www.israel-electric.co.il/Static/WorkFolder/HomeClients/pv-hahachlata-hamelea.pdf |date=2009-08-24 }} and USA have laws allowing microgenerated electricity to be sold into the national grid.

In January 2009, the Government of Alberta's Micro-Generation Regulation came into effect, setting rules that allow Albertans to generate their own environmentally friendly electricity and receive credit for any power they send into the electricity grid.

In December 2014, the Polish government will vote on a bill which calls for microgeneration, as well as large scale wind farms in the Baltic Sea as a solution to cut back on {{CO2}} emissions from the country's coal plants as well as to reduce Polish dependence on Russian gas. Under the terms of the new bill, individuals and small businesses which generate up to 40 kW of 'green' energy will receive 100% of market price for any electricity they feed back into the grid, and businesses who set up large-scale offshore wind farms in the Baltic will be eligible for subsidization by the state. Costs of implementing these new policies will be offset by the creation of a new tax on non-sustainable energy use.{{cite web|url=http://thenews.pl/1/12/Artykul/188486,Government-revises-sustainable-energy-bill|title=Government revises sustainable energy bill|access-date=2014-12-02|archive-date=2015-07-03|archive-url=https://web.archive.org/web/20150703074653/http://www.thenews.pl/1/12/Artykul/188486,Government-revises-sustainable-energy-bill|url-status=live}}

The United States has inconsistent energy generation policies across its 50 states. State energy policies and laws may vary significantly with location. Some states have imposed requirements on utilities that a certain percentage of total power generation be from renewable sources. For this purpose, renewable sources include wind, hydroelectric, and solar power whether from large or microgeneration projects. Further, in some areas transferable "renewable source energy" credits are needed by power companies to meet these mandates. As a result, in some portions of the United States, power companies will pay a portion of the cost of renewable source microgeneration projects in their service areas. These rebates are in addition to any Federal or State renewable-energy income-tax credits that may be applicable. In other areas, such rebates may differ or may not be available.

These schemes have been replaced in turn by new proposals from the Department for Energy and Climate Change (DECC) for clean energy cashback via Feed-In Tariffs[http://www.feedin-tariffs.com/what-are-feed-in-tariffs/ Clean energy cashback from Feed-In Tariffs] {{webarchive|url=https://web.archive.org/web/20100511001753/http://www.feedin-tariffs.com/what-are-feed-in-tariffs/ |date=2010-05-11 }} for generating electricity from April 2010 and the Renewable Heat Incentive[http://www.decc.gov.uk/en/content/cms/consultations/rhi/rhi.aspx Renewable Heat Incentive] {{webarchive|url=https://web.archive.org/web/20100922074802/http://decc.gov.uk/en/content/cms/consultations/rhi/rhi.aspx |date=2010-09-22 }} for generating renewable heat from 28 November 2011.

Feed-In Tariffs are intended to incentivise small-scale (less than 5MW), low-carbon electricity generation. These feed-in tariffs work alongside the Renewables Obligation (RO), which will remain the primary mechanism to incentivise deployment of large-scale renewable electricity generation. The Renewable Heat Incentive (RHI) in intended to incentivise the generation of heat from renewable sources. They also currently offer up to 21p per kWh from December 2011 in the Tariff for photovoltaics plus another 3p for the Export Tariff - an overall figure which could see a household earning back double what they currently pay for their electricity.{{cite web|url=http://www.fitariffs.co.uk/FITs/principles/export/|title=Export tariffs - FI Tariffs|access-date=2010-05-09|archive-date=2010-03-22|archive-url=https://web.archive.org/web/20100322200044/http://www.fitariffs.co.uk/FITs/principles/export/|url-status=live}}

On 31 October 2011, the government announced a sudden cut in the feed-in tariff from 43.3p/kWh to 21p/kWh with the new tariff to apply to all new solar PV installations with an eligibility date on or after 12 December 2011.{{cite web|url=http://www.decc.gov.uk/en/content/cms/news/pn11_091/pn11_091.aspx|title=Barker: Boom and bust for solar must be avoided - Announcements|publisher=decc.gov.uk|access-date=2011-11-21|archive-date=2011-11-15|archive-url=https://web.archive.org/web/20111115051543/http://www.decc.gov.uk/en/content/cms/news/pn11_091/pn11_091.aspx|url-status=live}}

Prominent British politicians who have announced they are fitting microgenerating facilities to their homes include the Conservative party leader, David Cameron, and the Labour Science Minister, Malcolm Wicks.
