Household energy insecurity refers to a household's inability to meet its energy needs. Household energy insecurity is a broad framework that includes a household's inability to afford energy costs as one of several factors in a household's ability to meet energy needs. Household energy insecurity is influenced by both internal and external factors such as energy cost, household income, housing conditions, and personal behavior. [1] The relevance of these factors may vary by geographic region, such as country or community, and the level of development of energy infrastructure. [2] Household energy insecurity is sometimes referred to as fuel poverty or as a form of energy poverty. [3]
When used in the context of developing countries, the term energy poverty is often used synonymously with household energy insecurity, i.e. the ability to afford energy within the home. In the context of developed countries, energy poverty more often refers to a lack of any access to modern energy infrastructure. [4]
The cost of energy relative to household income impacts affordability of energy. Households are generally defined as energy burdened if energy costs exceed 10% of gross household income. [1] In areas with more infrastructure and resources, households may face barriers to meeting energy needs due to the cost of purchasing, repairing, or maintaining equipment such as air conditioners or heating units as well as costs from running the equipment.
In areas with fewer infrastructure and resources, relative energy cost may impact type of fuel used, such as cheaper less efficient and more polluting fuels being used over more efficient and less polluting but costly fuels. [5]
Housing conditions such as household energy efficiency and the use of old or inefficient heating systems may impact energy insecurity Energy insecure households are more likely to report poor insulation or drafts in their home such as from windows or doors, [6] which may be more common in older or poorly maintained housing. Poorly insulated homes may have higher energy costs. Household energy efficiency improvements have also been associated with small but significant improvements in health. [7]
When faced with high energy costs, the concerns may influence energy-related behaviors at the household and individual levels. For example, Households are forced to make a decision on what basic needs to sacrifice. A common decision low income households have to make is linked to food insecurity, known as the "heat or eat" dilemma, where a household sacrifices food in order to address the household energy concerns. Also, households might try to reduce energy bills by reducing usage of energy systems by keeping their homes at temperatures that might either be too hot or cold. [8] [9]
Energy is considered a basic necessity as it allows for access to heating, lighting and cooking. Without this basic necessity it can lead to major health implications as studies have shown links with respiratory issues, mental health, and stress. [10] There is an increased chance of environmental exposures to dampness, mold, and thermal discomfort. [11] Women, children, and infants are most vulnerable to health effects caused by energy insecurity. [12]
One alternative to heating and cooking as a result of energy insecurity, common in developing countries, is burning solid fuels. [13] Death can be caused by smoky environments from inefficient stoves or from combustion of kerosene or coal for cooking. Around 600,000 lives are lost each year in Africa due to exposure of biomass smoke. [12]
A number of illnesses including cancer can exacerbate the problems associated with fuel poverty. [14]
An unprecedented global energy crisis and significant rise in the cost of fossil fuels in 2022 caused many governments to try to shelter consumers from higher energy prices and to accelerate the transition to clean energy technologies. Renewable energy has great potential to reduce prices and dependence on fossil fuels in short and long term. [15]
More research is needed into how household energy use and needs are related to climate change. [1] Improving household energy efficiency could co-benefit climate change mitigation by reducing household energy demand and usage, therefore reducing fossil fuel demand and emissions, while also reducing the health impacts of exposure to extreme temperatures that are more likely with climate change as well as impacts of household air pollution.
Climate change is increasingly influencing household energy insecurity in Australia, particularly through the intensity, frequency, and duration of temperature extremes. [16] Evidence indicates that rising temperatures heighten the risk of energy hardship, with vulnerable groups—such as older individuals, single-parent households, and rental tenants—being disproportionately affected. Quality housing and renewable energy solutions can help mitigate these risks. Projections suggest that under moderate to high emissions scenarios, the likelihood of energy hardship could rise by 0.1%−3.3% over the long term. This underscores the ongoing concern of energy insecurity, especially in colder regions less prepared for heat, highlighting the need for enhanced housing and community adaptations to address these challenges.
Energy insecurity is a global problem with contributing factors that may vary in different communities and countries. [1]
Household energy insecurity varies from region to region, there are differences between household energy insecurity for developed versus developing countries. Factors that can affect energy insecurity include income level, governance quality, trade openness, and foreign direct investment. [17] Growing and urbanizing countries or regions, for example certain countries in Asia, are at a rapid increase in demand for energy which causes an increase in energy insecurity. With an increase in energy demand, solutions lie in developing new technology or relying on energy imports from other countries. While the goal is to be self-sufficient, the effort to bring in modern technology to provide sustainable energy will be outpaced by the demand as well as population growth. [18]
While energy insecurity still focuses on energy access, it looks different in every country. In developed countries like the United States, we are examining households that miss bill payments, experience shut offs or live in housing with poor insulation. In developing countries such as some sub saharan African countries, we are focusing on any access or availability of reliable and clean energy. In developing countries, the availability and governance of energy is the main key compared to the issues such as low income and affordance in developed countries. [12]
The United States Energy Information Administration Residential Energy Consumption Survey (RECS) considers households to be energy insecure if they:
"have received a disconnection notice, have reduced or forgone basic necessities to pay energy bills, kept their houses at unsafe temperatures because of energy cost concerns, or been unable to repair heating or cooling equipment because of cost." [6]
In the United States, low-income households spend an average of over 8% of gross income on energy costs and household below the federal poverty line spend over 16% of gross income, based on 2016 American Community Survey estimates of household energy consumption. [19] In 2020, energy insecure households in the United States paid more for energy on average and per square foot than households not considered to be energy insecure. [6]
Studies done in the US, have proven that certain social characteristics and demographics are more likely to experience household energy insecurity than others. Some criteria to be considered energy insecure in the US include receiving a utility disconnection notice, experiencing a shutoff, or not being able to make a utility payment. Families most likely to be energy insecure are families 200% under the poverty line, have young children, or have no college degree. In terms of race, black and hispanic families are most likely to experience energy insecurity. [20]
Households in India may face barriers to energy access due to a lack of available and affordable clean sources of energy. [5] Costs for cooking and lighting can reach upwards of 20% of non-food expenditures in Indian households. [5] Energy sources used may differ between rural versus urban communities. Cooking and heating with biomass fuels such as wood or dung is declining but is still fairly prevalent, contributing to household air pollution and is associated with negative health effects. [24]
Nine percent of the EU population could not afford to heat their home sufficiently with Bulgaria scoring the highest of 39.2%. [25]
In the UK, fuel poverty is defined by the Warm Homes and Energy Conservation Act as: "a person is to be regarded as living "in fuel poverty" if he is a member of a household living on a lower income in a home which cannot be kept warm at reasonable cost". [26] Statistically, this used to be defined as a household needing to spend more than 10% of its income to maintain an adequate heating regime. However, definitions of "income" and "adequate heating regime" vary between UK Government and Devolved Administrations. [27] A new, more complex definition of fuel poverty is now used in the UK, based on the Hills review. [28] This gave the following definition: fuel poverty is now defined as when a household's required fuel costs are above the median level, and if they were to spend what is required, then the household would be left with a residual income below the official poverty line. Additionally, a Fuel Poverty Indicator has been created, which shows how far into fuel poverty households are, not simply if they are in poverty or not. [29]
Fuel poverty has been the focus of political action since the early 1970s. [30] In early 2008 it was estimated by Energywatch that there were around 4.4 million households in fuel poverty in the UK, with just over 3 million in England alone: this was more than double the number in 2003. [31] By April 2011 a YouGov survey indicated that the number of households in fuel poverty had risen to 6.3 million households, representing approximately 24% of all households in the UK. [32]
The cost of living is the cost of maintaining a certain standard of living for an individual or a household. Changes in the cost of living over time can be measured in a cost-of-living index. Cost of living calculations are also used to compare the cost of maintaining a certain standard of living in different geographic areas. Differences in the cost of living between locations can be measured in terms of purchasing power parity rates. A sharp rise in the cost of living can trigger a cost of living crisis, where purchasing power is lost and, for some people, their previous lifestyle is no longer affordable.
Electric power systems consist of generation plants of different energy sources, transmission networks, and distribution lines. Each of these components can have environmental impacts at multiple stages of their development and use including in their construction, during the generation of electricity, and in their decommissioning and disposal. These impacts can be split into operational impacts and construction impacts. All forms of electricity generation have some form of environmental impact, but coal-fired power is the dirtiest. This page is organized by energy source and includes impacts such as water usage, emissions, local pollution, and wildlife displacement.
National Energy Action (NEA) is a fuel poverty charity that works to eradicate fuel poverty and campaigns for greater investment in energy efficiency to help those who are poor or vulnerable gain affordable heat.
Energy is sustainable if it "meets the needs of the present without compromising the ability of future generations to meet their own needs." Definitions of sustainable energy usually look at its effects on the environment, the economy, and society. These impacts range from greenhouse gas emissions and air pollution to energy poverty and toxic waste. Renewable energy sources such as wind, hydro, solar, and geothermal energy can cause environmental damage but are generally far more sustainable than fossil fuel sources.
An economic analysis of climate change uses economic tools and models to calculate the magnitude and distribution of damages caused by climate change. It can also give guidance for the best policies for mitigation and adaptation to climate change from an economic perspective. There are many economic models and frameworks. For example, in a cost–benefit analysis, the trade offs between climate change impacts, adaptation, and mitigation are made explicit. For this kind of analysis, integrated assessment models (IAMs) are useful. Those models link main features of society and economy with the biosphere and atmosphere into one modelling framework. The total economic impacts from climate change are difficult to estimate. In general, they increase the more the global surface temperature increases.
Affordable housing is housing which is deemed affordable to those with a household income at or below the median, as rated by the national government or a local government by a recognized housing affordability index. Most of the literature on affordable housing refers to mortgages and a number of forms that exist along a continuum – from emergency homeless shelters, to transitional housing, to non-market rental, to formal and informal rental, indigenous housing, and ending with affordable home ownership. Demand for affordable housing is generally associated with a decrease in housing affordability, such as rent increases, in addition to increased homelessness.
In developing countries and some areas of more developed countries, energy poverty is lack of access to modern energy services in the home. In 2022, 759 million people lacked access to consistent electricity and 2.6 billion people used dangerous and inefficient cooking systems. Their well-being is negatively affected by very low consumption of energy, use of dirty or polluting fuels, and excessive time spent collecting fuel to meet basic needs.
In energy conservation and energy economics, the rebound effect is the reduction in expected gains from new technologies that increase the efficiency of resource use, because of behavioral or other systemic responses. These responses diminish the beneficial effects of the new technology or other measures taken. A definition of the rebound effect is provided by Thiesen et al. (2008) as, “the rebound effect deals with the fact that improvements in efficiency often lead to cost reductions that provide the possibility to buy more of the improved product or other products or services.” A classic example from this perspective is a driver who substitutes a vehicle with a fuel-efficient version, only to reap the benefits of its lower operating expenses to commute longer and more frequently."
Household air pollution (HAP) is a significant form of indoor air pollution mostly relating to cooking and heating methods used in developing countries. Since much of the cooking is carried out with biomass fuel, in the form of wood, charcoal, dung, and crop residue, in indoor environments that lack proper ventilation, millions of people, primarily women and children face serious health risks. In total, about three billion people in developing countries are affected by this problem. The World Health Organization (WHO) estimates that cooking-related pollution causes 3.8 million annual deaths. The Global Burden of Disease study estimated the number of deaths in 2017 at 1.6 million. The problem is closely related to energy poverty and cooking.
Renewable energy in developing countries is an increasingly used alternative to fossil fuel energy, as these countries scale up their energy supplies and address energy poverty. Renewable energy technology was once seen as unaffordable for developing countries. However, since 2015, investment in non-hydro renewable energy has been higher in developing countries than in developed countries, and comprised 54% of global renewable energy investment in 2019. The International Energy Agency forecasts that renewable energy will provide the majority of energy supply growth through 2030 in Africa and Central and South America, and 42% of supply growth in China.
In the United Kingdom, there are different definitions of fuel poverty. In England, a household is considered to be in fuel poverty if they are living in a property with an energy efficiency rating of band D or below, and if after heating their home to an adequate level, they fall below the official poverty line. In Northern Ireland, Scotland, and Wales, the definition of fuel poverty is whether a household needs to spend more than 10% of their income on energy bills to heat their home to an adequate level of warmth.To be considered adequate, the main living room needs to be 21 °C (70 °F), and other occupied rooms 18 °C (64 °F) during the daytime, with lower temperatures allowed at night.
Social class differences in food consumption refers to how the quantity and quality of food varies according to a person's social status or position in the social hierarchy. Various disciplines, including social, psychological, nutritional, and public health sciences, have examined this topic. Social class can be examined according to defining factors — education, income, or occupational status — or subjective components, like perceived rank in society. The food represents a demarcation line for the elites, a "social marker", throughout the history of the humanity.
Green affordable housing is reasonably priced housing that incorporates sustainable features. The phenomenon has become increasingly common in all over the world as climate change and the cost of housing become alarming issues. For example, the United States adopted state and local policies that favor or require green building practices for publicly owned or funded buildings. Potential benefits of green affordable housing include lower energy cost burden and improved health. One challenge to green affordable housing is the tendency to prioritize short-term costs over long-term benefits, leading to higher upfront cost. The challenge for green housing advocates is to see to the life cycle cost of the building. Many affordable housing projects already find it a challenge to raise capital to finance basic affordable housing. This challenge is compounded by the phenomenon of urban greening and environmental gentrification, which can drive up housing prices and becomes a challenge for green affordable housing. Green affordable housing has taken form in traditionally wooden homes, green homes and most recently with 'upcycling' shipping containers.
Sustainable refurbishment describes working on existing buildings to improve their environmental performance using sustainable methods and materials. A refurbishment or retrofit is defined as: "any work to a building over and above maintenance to change its capacity, function or performance' in other words, any intervention to adjust, reuse, or upgrade a building to suit new conditions or requirements". Refurbishment can be done to a part of a building, an entire building, or a campus. Sustainable refurbishment takes this a step further to modify the existing building to perform better in terms of its environmental impact and its occupants' environment.
Give Up LPG Subsidy is a campaign that was launched in March 2015 by the Indian government led by Prime Minister Narendra Modi. It is aimed at motivating LPG users who are able to afford to pay the market price for LPG to voluntarily surrender their LPG subsidy. As of 23 April 2016, 10 million people had voluntarily given up the subsidy. The surrendered subsidy is being redistributed by the government in order to provide cooking gas connections to poor families in rural households free of cost. Maharashtra, Uttar Pradesh, Karnataka, Delhi and Tamil Nadu are the top five states to give up the subsidy.
Housing insecurity is the lack of security in an individual shelter that is the result of high housing costs relative to income and is associated with poor housing quality, unstable neighborhoods, overcrowding, and homelessness.
Poverty and health are intertwined in the United States. As of 2019, 10.5% of Americans were considered in poverty, according to the U.S. Government's official poverty measure. People who are beneath and at the poverty line have different health risks than citizens above it, as well as different health outcomes. The impoverished population grapples with a plethora of challenges in physical health, mental health, and access to healthcare. These challenges are often due to the population's geographic location and negative environmental effects. Examining the divergences in health between the impoverished and their non-impoverished counterparts provides insight into the living conditions of those who live in poverty.
Energy poverty is defined as lacking access to the affordable sustainable energy service. Geographically, it is unevenly distributed in developing and developed countries. In 2019, there were an estimated 770 million people who have no access to electricity, with approximately 95% distributed in Asia and sub-Saharan Africa.
One aspect of energy poverty is lack of access to clean, modern fuels and technologies for cooking. As of 2020, more than 2.6 billion people in developing countries routinely cook with fuels such as wood, animal dung, coal, or kerosene. Burning these types of fuels in open fires or traditional stoves causes harmful household air pollution, resulting in an estimated 3.8 million deaths annually according to the World Health Organization (WHO), and contributes to various health, socio-economic, and environmental problems.
Urban heat inequity, also termed thermal inequity, is an unequal distribution of heat in urban areas or neighborhoods within them, which causes disproportionate impacts to people living in those communities. Unequal threat of heat stress in urban environments is often correlated with differences in demographics, including racial and ethnic background, income, education level, and age. While the general impacts of urban heat inequity depend on the city studied, negative effects typically act on historically marginalized communities. The idea is closely tied to the urban heat island effect, where a major cause to urban heat inequity is increased urbanization.
