The greatest challenge we face in becoming a 100 percent renewably powered city is not a technology, it's not implementation — it's our public being able to accept the change and being willing to put up with it.
|
|
And I hate to say it, but I think we will fail as a community if we succeed in being a 100 percent renewably powered city but only rich people can afford to live there and it's homogeneous.

Wind power has been supported by a renewable portfolio standard, passed in 2007, and strengthened in 2009, which requires 10% renewable energy from electric companies by 2010 and 25% by 2025. For 2013, in-state renewable generation was just 5.1% of Illinois' total generation. Additional renewably generated electricity is imported from other states. Illinois uses a large amount of electricity, and the state's mandate was enacted when only a very small percentage of its electricity was renewably generated. Illinois has the potential for installing up to an estimated 249,882 MW of wind generation capacity at a hub height of 80 meters operating at 30% gross capacity factor.

One grid energy storage method is to use off-peak or renewably generated electricity to compress air, which is usually stored in an old mine or some other kind of geological feature. When electricity demand is high, the compressed air is heated with a small amount of natural gas and then goes through turboexpanders to generate electricity. Compressed air storage is typically around 60–90% efficient.

PVC-based plumbing is selected for handling sewage because PVC resists biodegradation. Some packaging materials on the other hand are being developed that would degrade readily upon exposure to the environment. Examples of synthetic polymers that biodegrade quickly include polycaprolactone, other polyesters and aromatic-aliphatic esters, due to their ester bonds being susceptible to attack by water. A prominent example is poly-3-hydroxybutyrate, the renewably derived polylactic acid.

Revenue is produced by selling the electricity to the grid via an intermediary called Green Energy UK. Gigha residents control the whole project and profits are reinvested in the community. Findhorn Ecovillage has four Vestas wind turbines which can generate up to 750 kW. These make the community net exporters of renewably generated electricity. Most of the generation is used on-site with any surplus exported to the National Grid.

Most of the agricultural facilities in the developed world are mechanized due to rural electrification. Rural electrification has produced significant productivity gains, but it also uses a lot of energy. For this and other reasons (such as transport costs) in a low-carbon society, rural areas would need available supplies of renewably produced electricity. Irrigation can be one of the main components of an agricultural facility's energy consumption.

In order to be sustainable, impacts on anthropogenic capitals must be regenerative, so that nothing less than minimum levels of sufficiency (i.e., in the carrying capacities of the capitals) are maintained. Impacts on natural capitals, by contrast, must be constrained, so as not to exceed the limits of what nature can renewably provide. For impacts on natural capital, then, humans must live within their means; for impacts on all other capitals, they must continually recreate the means to live.

Serious concerns regarding the ethics of growing biodiesel in developing countries and importing the fuel to Europe have been raised on the grounds that they may replace much needed food crops. Converting any mainstream transport system to a renewable one also involves the conundrum that for consumers to use it the infrastructure must be in place, but high levels of use may be required to finance the infrastructure. Developments are thus slow at present and renewably powered vehicles very much the exception.

Facts of Brazil's Biomass The recent interest in converting biomass to electricity comes not only from its potential as a low- cost, indigenous supply of power, but for its potential environmental and developmental benefits. For example, biomass may be a globally important mitigation option to reduce the rate of CO2 buildup by sequestering carbon and by displacing fossil fuels. Renewably grown biomass contributes only a very small amount of carbon to the atmosphere. Locally, plantations can lessen soil erosion, provide a means to restore degraded lands, offset emissions and local impacts from fossil-fired power generation, and, perhaps, reduce demands on existing forests.

Berg visits Njord, an environmental organisation run by Marie Elvestad which researches and develops renewable energy solutions. After learning that the virus was developed a Njord engineer and cannot be removed, he agrees to promote the construction of hydroelectric dams to power Europe renewably rather than with oil. He also begin planning to convert Norway's offshore oil drilling platforms into wind power generators, and offers Elvestad the position of Climate Minister if he wins the upcoming election. At a press conference at a hydroelectric plant, a journalist tells Berg that one of the contractors, Stellux, previously trained Russian oil workers.

In Ohio, the nation's largest CCA was formed in 2000 when the state legislature adopted a CCA law that formed the Northeast Ohio Public Energy Council (NOPEC), made up of approximately 500,000 customers in 112 cities and towns across 8 counties, procured a power supply contract that switched electric generation fuel supply from a mix of coal and nuclear power to a mix of natural gas and a small percentage of renewably powered electricity, and announced a 70% air pollution reduction in the region's power mix. Unlike California CCAs, NOPEC offers both electric power(510,000 customers) and natural gas (400,000 customers). The Council has grown to 228 communities in 14 counties.

A German case study on storage of hydrogen in salt caverns found that if the German power surplus (7% of total variable renewable generation by 2025 and 20% by 2050) would be converted to hydrogen and stored underground, these quantities would require some 15 caverns of 500,000 cubic metres each by 2025 and some 60 caverns by 2050 – corresponding to approximately one third of the number of gas caverns currently operated in Germany. In the US, Sandia Labs are conducting research into the storage of hydrogen in depleted oil and gas fields, which could easily absorb large amounts of renewably produced hydrogen as there are some 2.7 million depleted wells in existence.

In March 2007, after extensive trials, c2c began fitting regenerative braking to its fleet, becoming the first UK train operator to do so. On 3 June 2007, the eve of World Environment Day, 357010 was given an all- over green vinyl sticker livery with the slogan "All c2c trains are greener now – find out more at – www.c2c-online.co.uk – c2c – the greener way to go" to highlight the completion of the scheme, which the company says has enabled energy savings of up to 20%. In October 2007, c2c announced that it had switched to renewably-generated electricity in all its stations, maintenance facilities and offices in a contract with E.ON UK, said to be the largest of its kind in the transport sector.

It also provides support to over 800 independent generators in the UK. Good Energy validates its claim of supplying 100% renewably generated electricity through the Renewable Energy Guarantee of Origin scheme. It also stated that on its main tariff it retires Renewables Obligation Certificates (ROCs) at an equivalent economic value of 5% above statutory compliance levels that apply to all electricity suppliers. In 2009 Dale Vince, chief executive of rival company Ecotricity, accused Good Energy of deliberately misleading customers over Renewables Obligation Certificates retirement and called on the National Consumer Council to amend or retract its report. However, Good Energy issued an open letter as a rebuttal, indicating the issue was a fair accounting matter: the company retired additional "ROC financial equivalents" rather than undiscounted ROCs, which was perhaps not well communicated to customers.

The European project Hyunder indicated in 2013 that for the storage of wind and solar energy an additional 85 caverns are required as it cannot be covered by PHES and CAES systems. A German case study on storage of hydrogen in salt caverns found that if the German power surplus (7% of total variable renewable generation by 2025 and 20% by 2050) would be converted to hydrogen and stored underground, these quantities would require some 15 caverns of 500,000 cubic metres each by 2025 and some 60 caverns by 2050 – corresponding to approximately one third of the number of gas caverns currently operated in Germany.

A kelp forest in San Clemente Island, California demonstrating the diversity of life that can be supported by Marine Permaculutre Marine Permaculture is a form of mariculture that reflects the principles of permaculture by recreating seaweed forest habitat and other ecosystems in nearshore and offshore ocean environments. Doing so enables a sustainable long-term harvest of seaweeds and seafood, while regenerating life in the ocean. Marine Permaculture comprises a platform from which seaweed ecosystems can be grown, creating the environmental conditions for primary production and habitat for marine life. Using a system of renewably powered pumps, cool, nutrient-rich waters are brought up from a depth of 100-500 meters, below the nutricline, to the ocean surface, thereby replicating natural overturning circulation processes of ocean upwelling and mitigating against marine heatwaves that have led to ocean stratification and decimated natural macroalgae ecosystems in many regions of the world.
