1 Energy Yesterday, Today, and Tomorrow Gateway Energy and the Environment 2011 Project Lead The Way, Inc.

2 Sustainable Energy Meets the needs of the present without compromising the ability of future generations to meet their needs Includes renewable and inexhaustible energy sources Hydroelectric, solar, wind, wave and tidal power, geothermal and biomass

3 Yesterday Burning Wood Heat Light Cooking

4 Yesterday Fossil Fuels Coal, oil, and natural gas formed from plants and animals that lived up to 300 million years ago. Fossil fuels are found in deposits beneath the Earth s surface. Fossil fuels are an exhaustible energy source because it takes millions of years for them to form. In the 19th century we started to extract and use fossil fuels for energy.

5 Energy Today 84% of U.S. energy consumption is still fossil fuels. 25% of U.S. energy needs are imported. 57% of the petroleum used in the U.S. is imported. What sources are changing? 2008 Renewables 7% Nuclear 8% 2013 Renewables 10% Nuclear 8% Petroleum 40% Natural Gas 22% Petroleum 36% Natural Gas 27% Coal 23% Coal 19% U.S. Energy Information Administration, Monthly energy Review, Table 1.3 and 10.1 (May 2014), 2013 data U.S. Energy Information Administration, Monthly energy Review, Table 1.3 and 10.1 (May 2014), 2013 data

6 Renewable Energy Today The 10% of renewable energy used in the United States is divided into 5 sources as shown below. These sources are sustainable and include both renewable and inexhaustible sources. Which category increased the most between 2008 and 2013? Hydroelectric 43% 2008 Solar 1% Geothermal 5% Wind 4% Hydroelectric 28% 2013 Solar 3% Geothermal 2% Wind 17% Biomass 47% Biomass 50% U.S. Energy Information Administration, Monthly energy Review, Table 1.3 and 10.1 (May 2014), 2013 data U.S. Energy Information Administration, Monthly energy Review, Table 1.3 and 10.1 (May 2014), 2013 data

7 How is Energy used? How does the United States use energy differently than the world? Why do you think the United States uses more energy for transportation? US World Transportation 28% Residential 22% Commercial 18% Transportation 20% Residential 18% Commercial 12% Industrial 32% Industrial 50% U.S. Energy Information Administration, Monthly energy Review, Table 1.3 and 10.1 (May 2014), 2013 data How much energy is consumed in the world by each sector?

8 Energy in the Future Petroleum At current levels of consumption, the world s oil reserves are expected to last about 40 years. There may be some oil that is currently undetected, but it cannot be economically extracted with current technology.

9 Energy in the Future Natural Gas Known gas reserves are expected to last about 60 years at current consumption levels with current technology.

10 Energy in the Future Coal If we continue to use coal at the current consumption rate, we expect to run out in about 200 years.

11 Energy in the Future We are using fossil fuels that were made more than 300 million years ago. They are not renewable; they can t really be made again. We can save fossil fuels by Conserving energy Using alternative energy sources

12 Alternative Energy Future More money and research will go into developing alternative energy sources. Nuclear Nonrenewable potential energy stored in the nucleus of an atom Biomass Renewable stored chemical energy from wood, garbage, and agricultural wastes Hydropower Inexhaustible gravitational energy of moving water Wind Inexhaustible kinetic energy from moving air

13 Alternative Energy Future Solar Inexhaustible radiant energy from the sun Geothermal Inexhaustible heat energy from beneath the Earth s surface Many career opportunities will involve research and development of alternative energy sources.

14 Smart Grid - Future Smart Grid technology changes the way we manage and distribute energy by making our current power grid more intelligent. A Smart grid delivers electricity from suppliers to consumers using digital technology to save energy, reduce cost and increase reliability. Smart Grid Smart Grid for Intelligent Energy Use
