How can we save energy? Saving energy means decreasing the amount of energy used while achieving a similar outcome of end use.
Energy tax[ edit ] Some countries employ energy or carbon taxes Energy saving motivate energy users to reduce their consumption.
Carbon taxes Energy saving force consumption to shift to nuclear power and other energy sources that carry different sets of environmental side effects and limitations.
On the other hand, taxes on all energy consumption can reduce energy use across the board while reducing a broader array of environmental consequences arising from energy production. The state of California employs a tiered energy tax whereby every consumer receives a baseline energy allowance that carries a low tax.
As usage increases above that baseline, the tax increases drastically. Such programs aim to protect poorer households while creating a larger tax burden for high energy consumers. Energy saving energy audit is an inspection and analysis of energy use and flows for energy conservation in a building, process or system with an eye toward reducing energy input without negatively affecting output.
This is normally accomplished by trained professionals and can be part of some of the national programs discussed above. Recent development of smartphone apps enables homeowners to complete relatively sophisticated energy audits themselves.
Advanced real-time energy metering can help people save energy by their actions. This is called passive solar design or climatic design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.
The key to designing a passive solar building is to best take advantage of the local climate. Elements to be considered include window placement and glazing type, thermal insulationthermal massand shading.
Passive solar design techniques can be applied most easily to new buildings, but existing buildings can be retrofitted.
Zoning reforms that allow greater urban density as well as designs for walking and bicycling can greatly reduce energy consumed for transportation. The use of telecommuting by major corporations is a significant opportunity to conserve energy, as many Americans now work in service jobs that enable them to work from home instead of commuting to work each day.
Consumer products[ edit ] An assortment of energy-efficient semiconductor LED lamps for commercial and residential lighting use. A prominent example of this is the energy savings that can be made by replacing an incandescent light bulb with a more modern alternative.
When purchasing light bulbs, many consumers opt for cheap incandescent bulbs, failing to take into account their higher energy costs and lower lifespans when compared to modern compact fluorescent and LED bulbs. Although these energy-efficient alternatives have a higher upfront cost, their long lifespan and low energy use can save consumers a considerable amount of money.
Many LED bulbs on the market qualify for utility rebates that further reduce the price of purchase to the consumer. However, health studies have demonstrated that headache, stressblood pressurefatigue and worker error all generally increase with the common over-illumination present in many workplace and retail settings.
Items such as stoves, dish washers, clothes dryers, hot water and incandescent lighting all add heat to the home. Low-power or insulated versions of these devices give off less heat for the air conditioning to remove.
The air conditioning system can also improve in efficiency by using a heat sink that is cooler than the standard air heat exchanger, such as geothermal or water.
In cold climates, heating air and water is a major demand on household energy use. Significant energy reductions are possible by using different technologies.
Heat pumps are a more efficient alternative to electrical resistance heaters for warming air or water. A variety of efficient clothes dryers are available, and the clothes lines requires no energy- only time. Natural-gas condensing boilers and hot-air furnaces increase efficiency over standard hot-flue models.
New construction implementing heat exchangers can capture heat from waste water or exhaust air in bathrooms, laundry and kitchens. In both warm and cold climate extremes, airtight thermal insulated construction is the largest factor determining the efficiency of a home.
Insulation is added to minimize the flow of heat to or from the home, but can be labor-intensive to retrofit to an existing home. Energy conservation by country[ edit ] Asia[ edit ] Despite the vital role energy efficiency is expected to play in cost-effectively cutting energy demand, only a small part of its economic potential is exploited in the Asia.
Governments have implemented a range of subsidies such as cash grants, cheap credit, tax exemptions, and co-financing with public-sector funds to encourage a range of energy-efficiency initiatives across several sectors.Energy saving shower heads are not new, but as part of the overall energy saving strategy will contribute significantly.
energy savings at home. Improving your home's energy efficiency with ENERGY STAR can help to lower high energy bills, improve comfort and reduce greenhouse gas emissions. Learn about the many ways to save in your home and track your progress with "My ENERGY STAR" - your new dashboard to savings.
ENERGY STAR® is the simple choice for energy efficiency.
For more than 20 years, EPA’s ENERGY STAR program has been America’s resource for saving energy and protecting the environment. The Energy-Saving Trees program only has a certain number of trees available each season. Unfortunately, all trees available for this season have been claimed.
Earning the ENERGY STAR certification means the product meets strict energy efficiency guidelines set by the US Environmental Protection Agency. Lighting products that have earned the ENERGY STAR label deliver exceptional features, while using less energy.
Saving energy helps you save money on.
When do BGE Energy Savings Days occur? BGE schedules Energy Savings Days when the demand for electricity is expected to be particularly high. This typically occurs on very hot summer weekdays when both homes and businesses are using higher amounts of electricity, especially with air conditioning.
