Reference excerpt

Home energy upgrades from public utilities are added home energy efficiency and renewable energy features planned or installed by public utilities. Help from a public utility can make it easier for a homeowner to select, install or operate climate-friendly components. The utility might assist with coordinated use of utility-supplied energy, building features, financing, operating options and neighborhood supplied energy.

Current programs Various public utilities, related organizations and governments have started or considered programs offering home energy upgrades from public utilities.

Australia In 2016 Greentech Media reported that Australian utilities were starting to offer home battery upgrades as a way to participate in a growing home battery storage market. Sellers of home storage batteries partnered with public utilities. By 2018 utilities were seeking a closer relationship with homeowners whose home storage batteries could help balance grid load and thus reduce the need for new conventional power plants.

The Bahamas

Ragged Island Ragged Island is an out island in The Bahamas archipelago. Ragged Island's electricity was originally provided using diesel generators. After the passage of hurricane Irma, the Bahamas Power and Light Company (BPL) developed a project to implement a Ragged Island microgrid that includes renewable energy. This microgrid offers protection from natural disasters and fuel price changes. The microgrid construction was undertaken by Tugliq Energy and its construction partner Salt Energy. The project includes design, procurement, installation and a year's operation of a solar-battery microgrid coupled with the existing diesel plant. The microgrid has a solar capacity of 402 kWp. The Ragged Island microgrid has been viewed as a proven standard model for rapid development of similar facilities worldwide.

China In 2016 China implemented a Standard for Energy Consumption of Residential Buildings, a critical step to guide property developers and owners. The Rocky Mountain Institute observed that "no other countries with building stock volume similar to China’s had released a similar national standard".

Colombia

Antioquia As explained in its 2020 website, the public utility of the Colombian city of Medellín, Empresas Publicas de Medellín (EPM), supported the city's efforts to be sustainable, focusing on providing low income residents with security, opportunity, a healthy environment and healthcare. Major Medellín programs have included construction of library parks, development of parks and urban green areas, development of plazas, and construction of an accessible and efficient transit system.

France On its website in 2020, Électricité de France (EDF) affirmed its commitment to putting residential customers' energy-saving plans into practice. EDF stated that it provides smart meters and ability to monitor energy consumption from computers or smartphones. EDF's website explains that residential customers "who want to invest in saving energy need look no further than EDF for precisely the right services and advice, from a home energy performance assessment to advice on heating systems (smart radiators, heat pumps, solar water heating, etc.) and the installation of energy-efficient solutions (LED lighting and heating system regulators and programmers)".

India In September 2016 the Climate Policy Initiative published an analysis of challenges facing India if its national and state governments and public utilities were to help property owners install rooftop solar projects. Considered help included financing, net metering, and installation. Participating organizations would be the Ministry of New and Renewable Energy, the Climate Policy Initiative, India's state governments, and state-level public electricity distribution companies.

United States Many programs have started in the United States. U.S. presidential candidate Joe Biden called attention to his climate change plan in July 2020. In December 2020 President Biden nominated key cabinet members and officials to implement climate policy. The Biden plan observed that “local housing authorities and utility companies have stepped up and helped households invest in energy-efficient upgrades by offering flexible financing plans and tax credits”. Biden's plan included incentives for efficiency improvements, appliance electrification, and on-site clean power generation. The plan called for developing “a package of affordable energy efficiency retrofits” and for changing building codes to increase the energy efficiency of new buildings. To encourage charging of electric vehicles at off-peak times, many public utilities in the United States have offered rebates for purchase or installation of home electric vehicle charging equipment.

Alaska

In 2018, Alaska’s capital city Juneau considered easing itself away from heating oil by using heat pumps powered from hydroelectricity. The local utility, Alaska Electric Light & Power, planned the first steps toward encouraging customers to install heat pumps. Heat pump installations may be air sourced or geothermal. (Available videos describe both air source and geothermal installations.)

Worked examples

Example 1 — a first encounter with Home energy upgrades from public utilities

Start with the simplest possible case. Write down what Home energy upgrades from public utilities claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Home energy upgrades from public utilities before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Home energy upgrades from public utilities ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Home energy upgrades from public utilities

In research: Home energy upgrades from public utilities appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Home energy upgrades from public utilities in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Home energy upgrades from public utilities is common in secondary-school and first-year university syllabi. It links to neighbouring topics Public utilities, Renewable energy, Renewable energy economics, so understanding it makes those chapters shorter.
In everyday life: Look for Home energy upgrades from public utilities outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
