Women Impacting Public Policy joined a recent White House Business Council Meeting to share how various policies are affecting women business owners across the country. The meeting included several White House staff along with top officials from the Department of Commerce and the Small Business Administration.

 

At the meeting, WIPP stressed the importance of capital access as the critical issue for women business owners looking to start and grow their companies, and highlighted WIPP's 2013 Annual Survey finding that it takes an average of two attempts for women business owners to secure funding.

 

Commerce Undersecretary for Economic Affairs, Mark Doms, agreed that the economy would be best served by giving business owners more access to capital. The Commerce Department's new strategic plan, America is Open for Business, reflects that priority by stressing innovation and investment.  

 

SBA Associate Administrator for Capital Access Ann Marie Mehlum concurred, saying her office will continue to identify opportunities to expand access while strengthening SBA's already available capital access programs. She went on to highlight the 7(a) loan program, which supported more than $15 billion in small business loans in FY13.

 

The meeting closed with a discussion of how trade can be used to fuel growth for businesses of all sizes. The Administration agreed there is a need for streamlining and simplification in exporting as well as engaging the women's business community on the value of selling goods and services abroad. Both of those priorities are at the front of WIPP's ExportNOW program that encourages women entrepreneurs to grow beyond our borders.

 

These meetings are open dialogues with policymakers, giving WIPP's advocacy team the opportunity to share ideas and concerns raised by WIPP's members.

Most women can't imagine a day without flipping on a light, powering up a computer, or microwaving their food.  But we rarely think about where that electricity comes from and the impact our electricity choices have on the environment, the air we breathe, and our economy. Every month at bill-paying time, we know how the power bill weighs on the household budget, and now it is more important than ever to make wise choices about the electricity we use.

 

How clean is my electricity?

- It depends on which sources of electricity are used.  Nuclear, hydro (water), wind, and solar are energy sources that don't emit air pollution or pollution that contributes to global warming.

 

Find out how clean your electricity is. 
- You can get information on your utility's fuel mix and emissions profile and even calculate the emissions your home or business produces.  Go to www.epa.gov/cleanenergy; look under "Energy and You."

 

Check your utility when you write your check.

- Check your utility's Web site for information on clean energy, conservation, and efficiency programs offered for your home or business.  Find out how your utility plans to provide cleaner electricity; let the utility know your position.

 

Think bigger picture - your state and our country

- Check your state and federal energy department Web sites for information on the growing number of incentive programs that fund energy efficiency and clean energy upgrades for your home or business.  Start with www.energy.gov for the U.S. Department of Energy.

 

Change your elected leaders along with your light bulbs.
- Pay attention to what policies local, state, and federal elected officials advocate.  Vote for leaders who will move our country towards clean energy sources.

 

Where does most of the electricity in my home go?

- Home owners use electricity for lighting, operating appliances, producing hot water and, in some cases, heating and cooling.

- On average, air conditioning consumes 16 percent; your refrigerator, 13.7 percent; water heating, 9.1 percent; space heating, 10.1 percent.  Lighting uses another 8.8 percent; clothes dryers, 5.8 percent; freezers, 3.5 percent; furnace fans, 3.3 percent; and color TVs, 2.9 percent.

- When coal and other fossil fuels are burned to create electricity, greenhouse gases are emitted into the atmosphere.  The average American home's electricity usage results in 18,000 pounds of carbon dioxide (CO2) a year released into the atmosphere.

 

What can I do in my home to help me save energy?

- Use warm or cold water in your washing machine.  And use clothes washers, dishwashers, and other electric appliances outside of peak hours.

 

Use programmable thermostats to adjust temperature settings according to daily and weekend patterns.

- Cool down a hot house at the end of the day.  That's more efficient than leaving the air conditioner running, even on a high temperature setting.

 

Buy Energy Star® room and central air-conditioning systems, windows, and appliances.

- Heating and insulation:  Have your heating, ventilating, and air conditioning (HVAC) system checked regularly; reduce heat loss by ensuring that your home has proper insulation in the walls, ceiling, floors, and attic.

- Replace incandescent light bulbs with compact fluorescent bulbs.

- Turn off computers and game systems when they're not in use. 

 

How can I save energy at work?

- A laptop computer uses less power than a desktop - from 30 to 90 percent less.  And the sleep mode dramatically decreases use.  Also, it takes no extra electricity to power up a computer, nor does it hurt the computer.  But leaving the computer on exposes it to risks such as damage from heat.  So be sure to set your sleep mode to kick in after 10 minutes of inactivity, then turn off your computer if you expect to be away for an hour or more. 

- Selecting energy-efficient office equipment - PCs, monitors, copiers, printers, fax machines - can result in enormous energy savings.

- Energy Star®-labeled office equipment is widely available and offers enormous energy savings - as much as 90 percent for some products.  Energy Star®-labeled office products use about half the electricity of standard equipment.  For example, Energy Star®-labeled computers use 70 percent less electricity than computers without this designation.  Aside from saving energy directly, these products can reduce air-conditioning loads and electromagnetic field emissions from monitors.

Turning the Light on Electricity

2:33 PM June 24, 2009

In October 1879, Thomas Edison unveiled the first commercially practical electric light bulb. Three years later, Edison's first power plant lit up New York City.

Today the industry that once brought "smokeless light" to American cities supplies power for homes, businesses, industries, and transportation, not to mention more than 176 million personal computers and a national network of more than 200 million cellular phones. America's demand for electricity is growing and is expected to increase at least 26 percent by 2030.

Electricity, one of our most widely used forms of energy, is a secondary energy source which we get by converting other sources of energy. These sources can be renewable - that is, virtually inexhaustible in duration and constantly replenished, but limited in the amount of energy that's available at a particular time. Hydro (water), wind, solar, geothermal, and biomass, for example, are renewable. Other sources may be nonrenewable - not replenished by nature - such as oil, coal, natural gas, and uranium for nuclear energy.

Generating electricity - that is, turning energy into electricity - is accomplished through several different methods including: 

§  Burning fossil fuels such as oil, coal, or natural gas

§  Using a nuclear reactor to produce boiling water that turns turbines producing electricity

§  Capturing kinetic energy from hydro or wind, and using solar and photovoltaic devices, called solar electric cells, that change sunlight directly into electricity.

Most of the electricity generated in the United States comes from burning coal. In fact, nearly half (49 percent) of the country's electricity uses coal as its energy source.

Electricity is usually delivered by a local utility company through the network of existing transmission and distribution lines often referred to as the "grid."

 

The Impact of Electricity on Global Warming and Health

The origin of the electricity we use is important because electricity generation is the dominant source of carbon dioxide (CO2) emissions in the U.S. today. In fact, the average American home's electricity usage results in 18,000 pounds of CO2 a year released into the atmosphere. Some sources of electricity produce emissions that damage the environment and endanger human health, while others do not.

The burning, or combustion, of fossil fuels such as coal, oil, and natural gas to generate electricity produces airborne gases and particulates that are released into the atmosphere. Some of these gases, such as CO2, are called greenhouse gases (GHGs); other GHGs include sulfur dioxide and nitrogen oxides. CO2 is the most prevalent GHG, and fossil-fuel burning electric power plants, especially coal, are its primary source. Coal-fired power plants are among the largest contributors of pollution from particulate matter, ozone and toxics, including mercury, lead, and arsenic. However, several new pollution-control technologies designed to reduce emissions of coal-related pollutants are in development.

According to the U.S. Environmental Protection Agency (EPA), GHGs are now at record-high levels in the atmosphere compared to the recent and distant past, and they threaten public health and welfare. These gases collect in the atmosphere, trap the sun's heat and cause the planet to warm up in the process we know as global warming.

The EPA warns that global warming is expected to cause more frequent and intense heat waves; wildfires; degraded air quality; heavier downpours and flooding; increased drought; greater sea level rise; more intense storms; and harm to water resources, agriculture, wildlife, and ecosystems.

Additionally, harmful health effects are associated with elevated greenhouse gas concentrations in the U.S.  Global warming is expected to worsen regional ozone pollution, with associated risks in respiratory infection, aggravation of asthma, and premature death. Certain climate-sensitive diseases are also expected to increase.

To reduce GHGs and other dangerous forms of air pollution, many experts believe we must decrease our dependence on fossil fuels and rely instead on energy sources that do not produce harmful airborne emissions.

 

Emission-free Energy Sources

Renewable energy sources such as hydroelectric, wind, solar, and geothermal produce virtually no emissions.  Nuclear energy also produces no GHGs in the production of electricity because nothing is burned.  

Among renewable energy sources that generate electricity, hydropower accounted for 6 percent of the nation's electric power in 2008. Other non-hydro renewables (biomass, geothermal, solar, and wind) accounted for approximately 3 percent of total electricity generated. Nuclear energy generated 20 percent of our nation's electricity. Of these emission-free sources, currently only hydropower and nuclear operate around the clock - 24/7 - to generate dependable power to consistently meet demand.

 

Nuclear

Nuclear plants, like plants that burn coal, oil, and natural gas, produce electricity by boiling water into steam. This steam then turns turbines to produce electricity. The difference is that nuclear plants do not burn anything.  Instead, they use uranium fuel in the shape of ceramic pellets to produce electricity through a process called fission.

Nuclear energy generates electricity from 104 reactors for one in five homes and businesses in the U.S. without emitting air pollution or contributing to global warming. In 2007, U.S. nuclear power plants avoided the emission of 1 million short tons of nitrogen oxides--the same amount emitted by more than 51 million passenger cars in a year. Generating nuclear power does, however, produce spent fuel that is stored safely onsite at nuclear plants or at designated facilities.

 

Hydroelectric

Hydroelectric power uses the kinetic energy of moving water to make electricity. The winds and the sun's heat cause water to evaporate. When this water vapor turns into rain or snow and flows downhill into rivers and streams, its energy can be captured using hydropower.

There are several types of hydropower facilities; some use dams and some do not. They range in size from small systems for a home or village to large projects producing electricity for utilities. Turbines and generators convert the energy into electricity, which is then fed into the electrical grid to be used in homes, businesses, and by industry.

Over one-half of the total U.S. hydroelectric capacity for electricity generation is concentrated in three states (Washington, California and Oregon), and Washington is the location of the nation's largest hydroelectric facility - the Grand Coulee Dam.

Conventional hydroelectric power is unlikely to enjoy rapid growth under current expectations, due to the lack of many additional large sites for hydroelectric facilities.

 

Wind

Wind power produces virtually no emissions. Wind energy is really a converted form of solar energy, created when the sun heats the earth's surface and the heat drives the winds. The wind produces energy that is captured by wind turbines. As long as the sun shines, the wind will blow.

Air in motion has kinetic energy. A wind energy system transforms the wind's kinetic energy into electrical energy that can be used. A wind turbine can harness the wind's energy; a generator then converts the mechanical energy into electrical energy for distribution and practical use. Wind electric turbines generate electricity for homes and businesses and for sale to utilities.

The most economical application of wind electric turbines is in groups of large machines called "wind power plants" or "wind farms."

Wind machines generated electricity in 28 states in 2008; the top five states with the most wind-power production are Texas, Iowa, California, Minnesota, and Washington. According to the American Wind Energy Association, wind energy could supply about 20 percent of the nation's electricity. 

 

Solar

Solar energy comes from the sun's rays - solar radiation - that reach the earth. Solar energy is convertible into other energy forms, such as electricity and thermal (heat) energy. Solar power converts the sun's energy into a pollution-free source of heat, lighting, and electricity.

Solar energy can be converted to electricity in two ways: Photovoltaic (PV) devices or "solar cells" change sunlight directly into electric power. PV systems are used to power watches, calculators, ATM machines, and lighted road signs. Solar thermal energy is often used to heat swimming pools, heating water used in homes, and space heating of buildings.

Around the U.S., available sunlight varies considerably as a result of differences in cloud cover and latitude, and also varies with the seasons. These variations must be taken into consideration when planning solar collection facilities. Solar power currently provides less than 1 percent of U.S. energy needs, but this percentage is expected to increase with the development of new and more efficient solar technologies.

 

Geothermal

Not all emission-free energy sources come from the sun. Geothermal energy taps the Earth's internal heat for many uses, including electric power production and the heating and cooling of buildings. Geothermal power plants use hydrothermal resources, which have two common ingredients: water (hydro) and heat (thermal). The Earth's heat can be drawn from several sources: hot water or steam reservoirs accessed by deep drilling, geothermal reservoirs located near the earth's surface (mostly located in western states, Alaska, and Hawaii), and the shallow ground near the Earth's surface that maintains a relatively constant temperature of 50°-60° F.

The U.S. generates more geothermal electricity than any other country, but the amount of electricity it produces is less than one-half of a percent of electricity produced in the U.S. States such as California, Nevada, Hawaii, and Utah have geothermal power plants, and other plants are in various stages of development in several other states. 

 

Biomass

Sunlight causes plants to grow. Biomass uses organic matter - wood or plants - called biomass to generate heat and electricity and produce transportation fuel. Biomass energy, or "bioenergy," recycles organic leftovers from forestry and agriculture - corn stalks and leaves, rice husks, wood waste, willow, pressed sugar cane, switchgrass - as fuel to produce electricity and heat. It can be fermented to produce fuels - ethanol, for example - for cars and trucks, it can create methane gas to power turbines, and it can be heated or "gasified" to break down into a clean-burning gas to make a range of products from diesel to gasoline to chemicals. Biomass helps reduce toxic air-borne pollutants and decrease our dependency on foreign oil.

According to the American Lung Association's report, Agenda for Clean Air: Protect the Air We Breathe, clean air remains one of the nation's major environmental and public-health challenges. "Climate, energy, and clean air are inexorably linked. Solutions that lead to cleaner air must be included in any approach to cleaner, more efficient energy use and reductions in global warming," the report states.
