Air Pollution - a Global Threat to our Health:  - Solid Fuel in Households (08:17)
Rating

Nearly one third of the world’s population are exposed to high levels of indoor air pollution from the household’s use of solid fuel. The fuel is mainly biomass burning under poor combustion conditions
in open fires or primitive stoves and with low ventilation. This costs more than 4 million lives every year and enormous suffering in particular among women and children.

Students are introduced to biofuels, biological engineers, algae and how they grow (photosynthesis), and what parts of algae can be used for biofuel (biomass from oils, starches, cell wall sugars). Through this lesson, plants—and specifically algae—are presented as an energy solution. Students learn that breaking apart algal cell walls enables access to oil, starch, and cell wall sugars for biofuel production. Students compare/contrast biofuels and fossil fuels. They learn about the field of biological engineering, including what biological engineers do. A 20-slide PowerPoint® presentation is provided that supports students taking notes in the Cornell format. Short pre- and post-quizzes are provided. This lesson prepares students to conduct the associated activity in which they make and then eat edible algal cell models.

Is climate change real? Yes, it is! And technologies to reduce Greenhouse Gas (GHG) emissions are being developed. One type of technology that is imperative in the short run is biofuels; however, biofuels must meet specifications for gasoline, diesel, and jet fuel, or catastrophic damage could occur. This course will examine the chemistry of technologies of bio-based sources for power generation and transportation fuels. We'll consider various biomasses that can be utilized for fuel generation, understand the processes necessary for biomass processing, explore biorefining, and analyze how biofuels can be used in current fuel infrastructure.

The world is driven by fossil fuels like oil and gas. This has some negative repercussions: Rising energy prices due to decreasing deposits, dependence on unstable oil and gas producing regimes and global warming.
It becomes clear, that a revolution in the way how we produce and use energy is necessary. Central to this energy transition are new technologies, which produce energy from renewable sources such as wind or sun.
With Germany as an example, this clip shows what renewable energies are and how they work as well as what the concept of energy transition means.

The clip is part of the WissensWerte Project of the german non-profit organization /e-politik.de/ e.V.

California's Energy Future: The View to 2050
Rating

In this two year study funded by the California Energy Commission and S.D. Bechtel, a committee of individuals from major energy research institutions in California develops strategies to meet Executive Order S-3-05. Executive Order S-3-05 requires California to reduce greenhouse gas (GHG) emissions to 80% of 1990 levels by 2050. To accomplish this, CO2 levels will need to drop from 13 tons CO2e per capita (2005) to 1.6 tons CO2e per capita (2050) while the population continues to grow and energy use is expected to double. To offer a solution to this challenge, multiple "energy system portraits" are developed with combinations of nuclear, biomass, electricity, and fossil fuels with carbon capturing systems. It's concluded by applying key aggressive strategies and investing in multiple technologies, implementations, research, development, and innovation, California can meet executive order S-3-05.

Dome It Challenge Scenario Cards
Conditions of Use:

Rating

Student teams find solutions to hypothetical challenge scenarios that require them to sustainably manage both resources and wastes. They begin by creating a card representing themselves and the resources (inputs) they need and wastes (outputs) they produce. Then they incorporate additional cards for food and energy components and associated necessary resources and waste products. They draw connections between outputs that provide inputs for other needs, and explore the problem of using linear solutions in resource-limited environments. Then students incorporate cards based on biorecycling technologies, such as algae photobioreactors and anaerobic digesters in order to make circular connections. Finally, the student teams present their complete biorecycling engineering solutions to their scenarios in poster format by connecting outputs to inputs, and showing the cycles of how wastes become resources.

Edible Algae Models
Conditions of Use:
No Strings Attached
Rating

Students make edible models of algal cells as a way to tangibly understand the parts of algae that are used to make biofuels. The molecular gastronomy techniques used in this activity blend chemistry, biology and food for a memorable student experience. The models use sodium alginate, which forms a gel matrix when in contact with calcium or moderate acid, to represent the complex-carbohydrate-composed cell walls of algae. Cell walls protect the algal cell contents and can be used to make biofuels, although they are more difficult to use than the starch and oils that accumulate in algal cells. The liquid juice interior of the algal models represents the starch and oils of algae, which are easily converted into biofuels.

Energy in a Changing World
Conditions of Use:

What is energy? It's the hot in heat, the glow in light, the push in wind, the pound in water, the sound of thunder and the crack of lightening. It is the pull that keeps us (and everything else!) from simply flying apart, and the promise of an oak deep in an acorn. It is all the same, and it is all different. Sunshine and waterfalls won't start your car, and wind won't run the dishwasher. But, if we match the form and timing of the energy with your needs, all of these things could be true. Energy in a Changing World is about the full arc of energy transformation, delivery, use, economics and environmental impact, especially climate change.

Have you seen a Clean Coal baseball cap? In the challenge to meet soaring energy demand with limited resources, volatile issues like those related to the environment, national security and public health are often addressed outside of normal market transactions and are called externalities, or nonmarket factors. Stakeholders can act in resourceful ways to create a nonmarket environment that best serves their interest. A firm may challenge a law that makes it expensive or difficult to do business or compete with others, for example. An individual may organize a boycott of products or services that violate the individual's interests or principles--hey, don't buy from them! Nonmarket strategy in the energy sector is the subject of this engaging course.
