Colonial Street is one of the backlot street sets at the Universal Studios Lot in Universal City, California . The street set has a long history, spanning over 60 years of movies and television. From 2004 to 2012, it was used in the filming of the TV series Desperate Housewives , in which the street was known as Wisteria Lane . After the production of Desperate Housewives ended, the street underwent a small makeover to remove the essence of Wisteria Lane, so that it could be used in other productions. As of May 2012 , most of the iconic white fencing and wisteria has been removed. Colonial Street has since been used for the NBC comedy About a Boy and the NBC series Telenovela , featuring Desperate Housewives star Eva Longoria .

The product was first unveiled in August 2016, but Tesla was only able to start producing the Solar Roof in volume in March 2020. A report released in March 2023 estimates that Tesla has installed approximately 3,000 solar roofs in
460-478: A cost increase of about 30% for all projects, including some that already had an agreed-upon start date. Tesla said that it would "be prioritizing customers based on the order in which they accept their updated agreements," potentially adding time for customers who had been waiting for months or a year for a new roof. On April 26, 2021, Elon Musk admitted that the company made "significant mistakes" in their solar roof tile project, including that they did not anticipate
552-620: A factory to produce lithium-ion batteries. The Tesla Energy brand was introduced on April 30, 2015, as CEO Elon Musk announced that the company would apply its battery technology to a home energy storage system called the Powerwall. Five hundred pilot units were built at the Tesla Fremont Factory in California and installed during 2015. The Giga Nevada factory started limited production of Powerwalls and Powerpacks in
644-437: A given unit of energy produced, the life-cycle greenhouse-gas emissions of natural gas are around 40 times the emissions of wind or nuclear energy but are much less than coal. Burning natural gas produces around half the emissions of coal when used to generate electricity and around two-thirds the emissions of coal when used to produce heat. Natural gas combustion also produces less air pollution than coal. However, natural gas
736-480: A long-term agreement and may ask Tesla to deactivate the system at anytime with no penalty; Tesla charges a flat fee to remove the system. Tesla uses proprietary mounting hardware on rooftops that eliminates the need for mounting rails and uses skirts that hide the hardware and make the panels appear to be flush with the roof. SolarCity acquired the mounting technology when it purchased Zep Solar in 2013. The "railless" system allows installers to install solar panels on
828-406: A path to net-zero emissions . Developing natural gas infrastructure risks carbon lock-in and stranded assets , where new fossil infrastructure either commits to decades of carbon emissions, or has to be written off before it makes a profit. The greenhouse gas emissions of fossil fuel and biomass power plants can be significantly reduced through carbon capture and storage (CCS). Most studies use
920-428: A quarter of all low-carbon energy , making it the second largest source after hydropower. Nuclear power's lifecycle greenhouse gas emissions—including the mining and processing of uranium —are similar to the emissions from renewable energy sources. Nuclear power uses little land per unit of energy produced, compared to the major renewables. Additionally, Nuclear power does not create local air pollution. Although
1012-465: A result of the shift in business model, total solar installations declined after the Tesla acquisition. In the second quarter of 2019, Tesla quarterly installations fell to a low of 29 megawatts, compared to SolarCity's installation of 253 megawatts in the fourth quarter of 2015 (before Tesla acquired it), and compared to 2,013 megawatts the residential leader Sunrun installed. Analysts believe that SolarCity

Biomass is renewable organic material that comes from plants and animals. It can either be burned to produce heat and electricity or be converted into biofuels such as biodiesel and ethanol, which can be used to power vehicles. The climate impact of bioenergy varies considerably depending on where biomass feedstocks come from and how they are grown. For example, burning wood for energy releases carbon dioxide; those emissions can be significantly offset if
1196-627: A small fraction of the energy in sunlight, producing a given amount of bioenergy requires a large amount of land compared to other renewable energy sources. Second-generation biofuels which are produced from non-food plants or waste reduce competition with food production, but may have other negative effects including trade-offs with conservation areas and local air pollution. Relatively sustainable sources of biomass include algae , waste, and crops grown on soil unsuitable for food production. Carbon capture and storage technology can be used to capture emissions from bioenergy power plants. This process
1288-487: A solar electric economy. The announcement cited (as benefits of the acquisition) operational and cost synergies, as well as allowing for integrated sales of products from Tesla's existing battery energy storage products division. The announcement of the deal resulted in a more than 10% drop in Tesla's stock price. The proposal for acquisition was approved by antitrust regulators in August 2016. More than 85% of unaffiliated shareholders of Tesla and SolarCity voted to approve
1380-401: A solar panel to produce as much energy as was used for its production. Less energy is needed if materials are recycled rather than mined. In concentrated solar power , solar rays are concentrated by a field of mirrors, heating a fluid. Electricity is produced from the resulting steam with a heat engine . Concentrated solar power can support dispatchable power generation , as some of the heat
1472-487: A sustainable way is a critical challenge for the global goal of limiting climate change while maintaining economic growth and enabling living standards to rise. Reliable and affordable energy, particularly electricity, is essential for health care, education, and economic development. As of 2020, 790 million people in developing countries do not have access to electricity, and around 2.6 billion rely on burning polluting fuels for cooking. Improving energy access in
1564-423: A working assumption that CCS can capture 85–90% of the carbon dioxide (CO 2 ) emissions from a power plant. Even if 90% of emitted CO 2 is captured from a coal-fired power plant, its uncaptured emissions are still many times greater than the emissions of nuclear, solar or wind energy per unit of electricity produced. Since coal plants using CCS are less efficient, they require more coal and thus increase
1656-569: Is Earth's primary source of energy, a clean and abundantly available resource in many regions. In 2019, solar power provided around 3% of global electricity, mostly through solar panels based on photovoltaic cells (PV). Solar PV is expected to be the electricity source with the largest installed capacity worldwide by 2027. The panels are mounted on top of buildings or installed in utility-scale solar parks . Costs of solar photovoltaic cells have dropped rapidly, driving strong growth in worldwide capacity. The cost of electricity from new solar farms
1748-407: Is a key component, in its 1987 report Our Common Future . It defined sustainable development as meeting "the needs of the present without compromising the ability of future generations to meet their own needs". This description of sustainable development has since been referenced in many definitions and explanations of sustainable energy. There is no universally accepted interpretation of how
1840-444: Is a major source of air pollution, which causes an estimated 7 million deaths each year, with the greatest attributable disease burden seen in low and middle-income countries. Fossil-fuel burning in power plants, vehicles, and factories is the main source of emissions that combine with oxygen in the atmosphere to cause acid rain . Air pollution is the second-leading cause of death from non-infectious disease. An estimated 99% of
1932-402: Is a potent greenhouse gas in itself, and leaks during extraction and transportation can negate the advantages of switching away from coal. The technology to curb methane leaks is widely available but it is not always used.

The first prototype Powerpacks were installed in 2012 at the locations of a few industrial customers. After July 22, 2022,
2300-472: Is competitive with, or in many places, cheaper than electricity from existing coal plants. Various projections of future energy use identify solar PV as one of the main sources of energy generation in a sustainable mix. Most components of solar panels can be easily recycled, but this is not always done in the absence of regulation. Panels typically contain heavy metals , so they pose environmental risks if put in landfills . It takes fewer than two years for
2392-504: Is controversial. Nuclear power does not produce carbon pollution or air pollution, but has drawbacks that include radioactive waste , the risk of nuclear proliferation , and the risk of accidents . Switching from coal to natural gas has environmental benefits, including a lower climate impact , but may lead to a delay in switching to more sustainable options. Carbon capture and storage can be built into power plants to remove their carbon dioxide (CO 2 ) emissions, but this technology
2484-439: Is controversy over whether nuclear power is sustainable, in part due to concerns around nuclear waste , nuclear weapon proliferation , and accidents . Radioactive nuclear waste must be managed for thousands of years and nuclear power plants create fissile material that can be used for weapons. For each unit of energy produced, nuclear energy has caused far fewer accidental and pollution-related deaths than fossil fuels, and
2576-661: Is expensive and has rarely been implemented. Fossil fuels provide 85% of the world's energy consumption, and the energy system is responsible for 76% of global greenhouse gas emissions. Around 790 million people in developing countries lack access to electricity , and 2.6 billion rely on polluting fuels such as wood or charcoal to cook. Cooking with biomass plus fossil fuel pollution causes an estimated 7 million deaths each year. Limiting global warming to 2 °C (3.6 °F) will require transforming energy production , distribution, storage, and consumption. Universal access to clean electricity can have major benefits to
2668-466: Is harvested unsustainably. Bioenergy feedstocks typically require significant amounts of energy to harvest, dry, and transport; the energy usage for these processes may emit greenhouse gases. In some cases, the impacts of land-use change , cultivation, and processing can result in higher overall carbon emissions for bioenergy compared to using fossil fuels. Use of farmland for growing biomass can result in less land being available for growing food . In
2760-420: Is known as bioenergy with carbon capture and storage (BECCS) and can result in net carbon dioxide removal from the atmosphere. However, BECCS can also result in net positive emissions depending on how the biomass material is grown, harvested, and transported. Deployment of BECCS at scales described in some climate change mitigation pathways would require converting large amounts of cropland. Marine energy has

2944-955: Is ongoing. Hydroelectric plants convert the energy of moving water into electricity. In 2020, hydropower supplied 17% of the world's electricity, down from a high of nearly 20% in the mid-to-late 20th century. In conventional hydropower, a reservoir is created behind a dam. Conventional hydropower plants provide a highly flexible, dispatchable electricity supply. They can be combined with wind and solar power to meet peaks in demand and to compensate when wind and sun are less available. Compared to reservoir-based facilities, run-of-the-river hydroelectricity generally has less environmental impact. However, its ability to generate power depends on river flow, which can vary with daily and seasonal weather. Reservoirs provide water quantity controls that are used for flood control and flexible electricity output while also providing security during drought for drinking water supply and irrigation. Hydropower ranks among
3036-482: Is produced from the steam created in underground reservoirs. Geothermal energy provided less than 1% of global energy consumption in 2020. Geothermal energy is a renewable resource because thermal energy is constantly replenished from neighbouring hotter regions and the radioactive decay of naturally occurring isotopes . On average, the greenhouse gas emissions of geothermal-based electricity are less than 5% that of coal-based electricity. Geothermal energy carries

3220-491: Is the largest source of renewable electricity while solar and wind energy are growing rapidly. Photovoltaic solar and onshore wind are the cheapest forms of new power generation capacity in most countries. For more than half of the 770 million people who currently lack access to electricity, decentralised renewable energy such as solar-powered mini-grids is likely the cheapest method of providing it by 2030. United Nations targets for 2030 include substantially increasing
3312-448: Is to use fewer materials whose production requires a lot of energy, for example through better building design and recycling. Behavioural changes such as using videoconferencing rather than business flights, or making urban trips by cycling, walking or public transport rather than by car, are another way to conserve energy. Government policies to improve efficiency can include building codes , performance standards , carbon pricing , and
3404-567: Is typically stored to enable electricity to be generated when needed. In addition to electricity production, solar energy is used more directly; solar thermal heating systems are used for hot water production, heating buildings, drying, and desalination. Wind has been an important driver of development over millennia, providing mechanical energy for industrial processes, water pumps, and sailing ships. Modern wind turbines are used to generate electricity and provided approximately 6% of global electricity in 2019. Electricity from onshore wind farms

#17327824454534784-699: The company over $ 1.5 billion in debt by 2016. SolarCity's leases were also criticized by consumer advocates and government regulators. Tesla Energy's business model is based around making their systems "the lowest-cost solar in the United States". As of 2021, the company sells systems at $ 2 per watt for solar panels before federal tax credits. Tesla says the business model was enabled by eliminating door-to-door sales, advertising, and some complex financing instruments (like leases). The shift in business model has been blamed for diminished customer support. Customers said they waited weeks for replies to emails and experienced long delays for administrative steps to be completed. As

The company focuses primarily on residential customers who purchase
5152-1194: The concept of sustainability applies to energy on a global scale. Working definitions of sustainable energy encompass multiple dimensions of sustainability such as environmental, economic, and social dimensions. Historically, the concept of sustainable energy development has focused on emissions and on energy security . Since the early 1990s, the concept has broadened to encompass wider social and economic issues. The environmental dimension of sustainability includes greenhouse gas emissions , impacts on biodiversity and ecosystems, hazardous waste and toxic emissions, water consumption, and depletion of non-renewable resources. Energy sources with low environmental impact are sometimes called green energy or clean energy . The economic dimension of sustainability covers economic development, efficient use of energy, and energy security to ensure that each country has constant access to sufficient energy. Social issues include access to affordable and reliable energy for all people, workers' rights , and land rights.

In July 2018, three former employees filed a lawsuit against SolarCity, alleging that the corporation had approved the creation of "fake sales accounts", which resulted in an "unreasonably high valuation of SolarCity" for investors. After allegedly informing management, including CEO Elon Musk, of these incidents,
6624-461: The product was no longer listed for sale. For large-scale customers, Tesla Energy operates an online platform which allows for automated, real-time power trading, demand forecasting and product control. In March 2021, the company said its online products were managing over 1.2 GWh of storage. For home customers, the company operates a virtual power company in Texas called Tesla Electric, which uses
6716-525: The proportion of renewable energy in the world's energy supply. According to the International Energy Agency, renewable energy sources like wind and solar power are now a commonplace source of electricity, making up 70% of all new investments made in the world's power generation. The Agency expects renewables to become the primary energy source for electricity generation globally in the next three years, overtaking coal. The Sun
6808-563: The purchase of SolarCity was done solely to benefit his cousin Lyndon Rive ( Co-founder of SolarCity) and Elon Musk and came at the expense of Tesla and its shareholders. Tesla directors settled the lawsuit in January 2020, leaving Musk the sole remaining defendant. In 2022, a Delaware court ruled in favor of Musk. "[The] Tesla Board meaningfully vetted the Acquisition, and Elon did not stand in its way. Equally if not more important,
6900-592: The release of toxins into the environment, and water scarcity. As of 2019, 85% of the world's energy needs are met by burning fossil fuels. Energy production and consumption are responsible for 76% of annual human-caused greenhouse gas emissions as of 2018. The 2015 international Paris Agreement on climate change aims to limit global warming to well below 2 °C (3.6 °F) and preferably to 1.5 °C (2.7 °F); achieving this goal will require that emissions be reduced as soon as possible and reach net-zero by mid-century. The burning of fossil fuels and biomass
6992-412: The roof more quickly than other installation approaches. Traditionally, solar panel installation requires workers to first outfit roofs with mounting rails and then attach solar panels to those rails. Tesla Energy manufactures, installs and sells a solar shingle product it calls the Tesla Solar Roof. Solar shingles are small solar panel tiles that can make up an entire roof surface. The company claims that
7084-539: The same goods or services, or delivering comparable services with less goods—is a cornerstone of many sustainable energy strategies. The International Energy Agency (IEA) has estimated that increasing energy efficiency could achieve 40% of greenhouse gas emission reductions needed to fulfil the Paris Agreement's goals. Energy can be conserved by increasing the technical efficiency of appliances, vehicles, industrial processes, and buildings. Another approach
7176-471: The shingles in volume until March 2020 and Panasonic left the joint venture in early 2020, before it exited the solar business entirely in January 2021. In mid-2017, several of the former SolarCity executives left the company. Chief policy officer John Wellinghoff departed in April 2017, co-founder Lyndon Rive left in June 2017, and his brother Peter left shortly thereafter. Tesla Energy shifted its business model compared to SolarCity, with Tesla saying that it
7268-575: The smallest share of the energy market. It includes OTEC , tidal power , which is approaching maturity, and wave power , which is earlier in its development. Two tidal barrage systems in France and in South Korea make up 90% of global production. While single marine energy devices pose little risk to the environment, the impacts of larger devices are less well known. Switching from coal to natural gas has advantages in terms of sustainability. For
7360-545: The solar company idea to the Rive brothers and he later served as the chairman of SolarCity. In June 2014, SolarCity committed to building a second factory, later called Giga New York , in Buffalo, New York , that would build photovoltaic cells and would be triple the size of the next largest photovoltaic manufacturing plant in the United States. By 2016, SolarCity had installed solar energy systems for over 325,000 customers and
7452-420: The solar inverter is capable of receiving over-the-air updates through built-in cellular connectivity. The product has been noted for using older string inverter technology (many systems now use micro-inverters ), but that it has the potential to drive the cost of Tesla's solar systems even lower. EnergySage , a solar buyers guide website, gave the Tesla Solar Inverter a rating of "very good", generally praising
7544-418: The surrounding population at risk. Geothermal energy is produced by tapping into deep underground heat and harnessing it to generate electricity or to heat water and buildings. The use of geothermal energy is concentrated in regions where heat extraction is economical: a combination is needed of high temperatures, heat flow, and permeability (the ability of the rock to allow fluids to pass through). Power
7636-490: The system with cash or financing. Tesla Energy also offers systems to commercial customers in California. Tesla Energy does not have a lease program like SolarCity, but between August 2019 and May 2021, it offered "subscription" systems to customers in Arizona, California, Connecticut, Massachusetts, New Jersey and New Mexico, in a plan to boost residential solar deployments. As opposed to a lease, customers did not need to sign
7728-422: The trees that were harvested are replaced by new trees in a well-managed forest, as the new trees will absorb carbon dioxide from the air as they grow. However, the establishment and cultivation of bioenergy crops can displace natural ecosystems , degrade soils , and consume water resources and synthetic fertilisers. Approximately one-third of all wood used for traditional heating and cooking in tropical areas
7820-414: The trouble of "assessing the difficulty of certain roofs [as the] complexity of roofs varies". Facing a class-action lawsuit filed by Solar Roof customers, Tesla revealed that it planned to let some customers who had signed contracts before the April 2021 price changes revert to their original price. Clean energy Energy is sustainable if it "meets the needs of the present without compromising
7912-401: The turbines can cause annoyance and constrain construction near densely populated areas. Wind power, in contrast to nuclear and fossil fuel plants, does not consume water. Little energy is needed for wind turbine construction compared to the energy produced by the wind power plant itself. Turbine blades are not fully recyclable, and research into methods of manufacturing easier-to-recycle blades
8004-796: The wind blows and the sun shines. Switching to renewable energy can therefore require electrical grid upgrades, such as the addition of energy storage . Some processes that are difficult to electrify can use hydrogen fuel produced from low-emission energy sources. In the International Energy Agency 's proposal for achieving net zero emissions by 2050, about 35% of the reduction in emissions depends on technologies that are still in development as of 2023. Wind and solar market share grew to 8.5% of worldwide electricity in 2019, and costs continue to fall. The Intergovernmental Panel on Climate Change (IPCC) estimates that 2.5% of world gross domestic product (GDP) would need to be invested in
8096-614: The world's population lives with levels of air pollution that exceed the World Health Organization recommended limits. Cooking with polluting fuels such as wood, animal dung, coal, or kerosene is responsible for nearly all indoor air pollution, which causes an estimated 1.6 to 3.8 million deaths annually, and also contributes significantly to outdoor air pollution. Health effects are concentrated among women, who are likely to be responsible for cooking, and young children. Environmental impacts extend beyond
8188-582: Was "a big source of the cash-flow deficit" for Tesla in 2019. In 2022, the company deployed solar energy systems capable of generating 348 megawatts (MW), an increase of 1% over 2021, and deployed 6.54 gigawatt-hours (GWh) of battery energy storage products, an increase of 62% over 2021. The battery figure was helped by the output of the company's Megapack factory in Lathrop, California, announced in October 2021. The division generated $ 3.91 billion in revenue for
8280-460: Was focusing on projects with higher margins, such as those that include a Powerwall. SolarCity heavily focused on door-to-door sales of leased systems, where customers would pay no upfront costs, but agree to purchase the power generated by those panels from the company for 20 years. Leases became the most popular solar business model in the US and made SolarCity the largest residential installer, but left
8372-426: Was one of the largest solar installation companies in the United States. On August 1, 2016, Tesla announced that it would be acquiring SolarCity in an all-stock $ 2.6 billion acquisition. Tesla's mission since its inception has been "to accelerate the world's transition to sustainable energy ". Musk said the purchase would advance Tesla's mission by helping the world move from a mine-and-burn hydrocarbon economy towards
8464-405: Was overhauled for Tom Hanks comedy The 'Burbs . The old Leave It to Beaver home was removed. Following the movie, the homes were rearranged again so Circle Drive was connected once again. Among the most noticeable changes were the removals of a church facade, seen on Murder She Wrote , in order to make room for Edie's house, and of the so-called Colonial Mansion, which was replaced by
