3 History of Energy in the United States What is the primary source of energy today? 100 years ago, what was the main source of energy in the United States?
US Energy History in the 1800s – Coal was America’s primary energy source, coal oil is bad for the environment, and today we use terrible working conditions in the mines.
6 US energy production has produced more natural gas in recent years. Effect? Coal production is unsustainable Environmental concerns Renewable energy production is not growing
7 Against Renewable Energy Against Renewable Energy Renewable Energy – Our energy resources are not running out Non-Renewable Energy – Limited energy resources that are depleting 20% of the world’s energy from renewable sources and 3% from road transport (cars)
9 Global Energy Production Most energy comes from non-renewable fossil fuels Oil and coal are the largest energy sources, followed by natural gas Renewable energy is not widely used in developing countries (cost of generation)
10. How has global renewable energy production changed over the past 10 years? Renewable energy is growing worldwide, but only in some developed countries
12 Global Energy Consumption Why do North America, Western Europe, Australia, and some countries in the Middle East consume the most energy per capita? Why do parts of sub-Saharan Africa and Southeast Asia have the lowest energy consumption (per capita)?
14 Major Energy Sources North America – Large fossil fuel reserves of natural gas, oil, and coal Transportation in Europe – Natural gas, nuclear power, and environmentally friendly renewables East Asia – Cheap coal, no oil. Southwest Asia has large reserves of oil and gas.
16 The impact of different types of renewable energy on the environment Wind is a completely clean energy source Geothermal energy is the extraction of energy from the heat of the earth’s surface. Air pollution is low, but much less than coal or petroleum biofuels (biomass, ethanol, biodiesel). There are huge environmental and economic costs to growing plants, but they are burned as clean energy
17 Ethanol is a fuel produced from corn (a renewable resource) that pollutes less than gasoline, but is not an efficient fuel.
19 Different types of renewable energy Environmental impact Hydropower – using water from dammed rivers does not cause air pollution, but the main environmental impact is preventing fish migration. Pollution (other than battery production)
Environmental impact of non-renewable energy sources of coal – mass production of natural gas and oil – air, water and land – air pollution, pollution of waters and beaches contributing to global warming Nuclear reactors have minimal impact if nuclear waste is not disposed of (highly toxic)
25 reviews! 1. What was the main source of American power in the 19th century? 2. Identify two energy sources that have a negative impact on the Earth 3. Why do you think Europe uses more nuclear and renewable energy than other continents? 4. Do you support the use of biofuels? Why and why? 5. What is the relationship between GDP per capita and the type of energy consumed in a country? 6. Why do Africa and Southeast Asia use so much coal and oil?

For this reason, it seems that renewable energies, when implemented, will play a major role in reducing the transmission and transition of clean energy.
Or other greenhouse gases in the atmosphere, for this reason and because of the active use of renewable energy such as wind and solar energy, the terms “renewable energy” and “carbon energy” are sometimes confused. But not all renewable energy is carbon, and not all carbon is renewable
Biofuel and bioenergy are renewable sources: we can regenerate plants that are burned for fuel. But they are not carbon neutral, growing plants absorb CO
Or another greenhouse gas, but it’s not renewable. Nuclear reactors use uranium, and if we run out of uranium, we can never get it back.
Some forms of renewable energy can provide transportation fuel (such as biofuels) or heating and cooling of buildings (such as geothermal). However, most of the renewable energy is used to generate electricity. In 2018, 26% of the world’s electricity was generated from renewable energy sources, and this number is increasing every year.
More than 60 percent of the world’s renewable electricity comes from hydropower, which has been widely used since its invention, but today wind and solar power are growing rapidly.
Renewable energy presents great challenges and opportunities for electricity generation. Some renewable energy sources, such as wind and solar, are “variable,” meaning that the amount of electricity they produce varies depending on the amount of wind or sunlight. This can cause problems for system operators, especially when there is a mismatch between the amount of electricity needed and the amount of wind or solar. Another challenge is that the best places to generate renewable energy are often far away from areas that consume that electricity. For these reasons, adding more renewable energy sources to our electricity grids will require more changes, including more energy storage, backup generation, strategies to match energy consumption with periods of high energy production, and long-distance electricity transmission infrastructure.
Renewable energy is also well established and needs to compete with cheap fossil fuels. Renewable energy has grown rapidly over the past decade thanks to policy support (tax incentives, R&D funding, and renewable energy requirements) and cost reductions (especially in solar photovoltaics and wind turbines). Global wind and solar power has grown from 32 TWh in 2000 to 1,857 TWh in 2018: enough to power all of India.
As societies strive to reduce greenhouse gas emissions, renewable energy is expected to play an important role, especially if we provide more heat and transportation power and address the issue of large-scale energy storage. How much energy we get from renewables also depends on our ability to compete with nuclear, coal and other low-carbon technologies like storage and hydrogen.
The use of natural heat from the earth’s surface is usually used to heat and cool buildings, but sometimes to generate electricity.

Definition of energy storage Energy storage is a technology that stores energy at one time so that it can be used at another time. The storage of cheap and abundant energy is a key challenge for low-carbon energy systems.
Definition of Nuclear Energy Nuclear energy is low-carbon energy that breaks the bonds that hold the particles together in atoms.
Definition of Carbon Capture Carbon capture and storage is a technology that captures carbon dioxide from burning fuels before they are released into the atmosphere. Throughout human history, most of the energy used for many activities, from heating homes to industrial purposes, has been renewable energy. . These include solar, wind, plant, water and geothermal energy. The transition to renewable energy began in the 1900s, and by the mid-1900s they had become the main source of energy.
Non-renewable energy is a finite natural resource that cannot be replenished at the rate it is consumed. This type of energy comes from exhaustible sources and cannot be replenished in our lifetime. It takes millions of years to form
Non-renewable energy comes mainly from biomass fuels, which are produced by the decay of plants and animals buried beneath rocks and other materials in the Earth’s crust.
