Vitality Efficiency and Renewable Energy Chapter 16

Slide 2

16-1 Why Is Energy Efficiency an Important Energy Resource? Idea 16-1 We could spare as much as 43% of all the vitality we use by enhancing vitality effectiveness.

Slide 3

We Waste Huge Amounts of Energy (2) Four broadly utilized gadgets that waste vitality Incandescent light Motor vehicle with an inner burning motor Nuclear influence plant Coal-let go influence plant Possible choices for the "obsolete four"

Slide 4

Net Energy Efficiency—Honest Energy Accounting Net vitality proficiency the main vitality that matters

Slide 5

Comparison of the Net Energy Efficiency for Two Types of Space Heating

Slide 6

We Can Save Energy and Money in Industry (1) Cogeneration or joined warmth and influence (CHP) Replace vitality squandering electric engines Recycling materials Switch from low-effectiveness brilliant lighting to higher-productivity fluorescent and LED lighting

Slide 7

Average Fuel Economy of New Vehicles Sold in the U.S. furthermore, Other Countries

Slide 8

More Energy-Efficient Vehicles Are en route Superefficient and ultralight autos Gasoline-electric half and half auto Plug-in cross breed electric vehicle

Slide 9

Solutions: A Hybrid-Gasoline-Electric Engine Car and a Plug-in Hybrid Car

Slide 10

Science Focus: The Search for Better Batteries Current impediments Storage limit Overheating Flammability later on Lithium-particle battery Ultracapacitor Viral battery Using nanotechnology

Slide 11

We Can Design Buildings That Save Energy and Money (1) Green engineering Living or green rooftops Straw bunch houses

Slide 12

A Green or Living Roof in Chicago, IL (U.S.)

Slide 13

We Can Save Energy and Money in Existing Buildings (2) Heat water all the more effectively Use vitality proficient apparatuses Use vitality productive lighting

Slide 14

A Thermogram Showing Heat Loss Around Houses and Stores

Slide 15

Attic • Hang intelligent thwart close rooftop to reflect warm. • Use house fan. • Be certain upper room protection is no less than 30 centimeters (12 inches). Outside Plant deciduous trees to square summer sun and let in winter daylight. Washroom • Install water-sparing toilets, spigots, and shower heads. • Repair water spills speedily. Different rooms • Use minimized fluorescent lights or LEDs and abstain from utilizing glowing globules wherever conceivable. • Turn off lights, PCs, TV, and other electronic gadgets when they are not being used. • Use high productivity windows; utilize protecting window covers and close them around evening time and on sunny, hot days. • Set indoor regulator as low as you can in winter and as high as you can in summer. • Weather-strip and caulk entryways, windows, light installations, and divider attachments. • Keep warming and cooling vents free of hindrances. • Keep chimney damper shut when not being used. • Use fans rather than, or alongside, cooling. Kitchen • Use microwave as opposed to stove or broiler however much as could be expected. • Run just full loads in dishwasher and utilize low-or no-warm drying. • Clean cooler loops frequently. Storm cellar or utility room • Use front-stacking garments washer. In the event that conceivable run just full loads with warm or chilly water. • Hang garments on racks for drying. • Run just full loads in garments dryer and utilize bring down warmth setting. • Set water warmer at 140° if dishwasher is utilized and 120° or lower if no dishwasher is utilized. • Use water radiator warm cover. • Insulate uncovered high temp water funnels. • Regularly perfect or supplant heater channels.

Solutions: Passive and Active Solar Heating for a Home

Slide 17

Trade-Offs: Passive or Active Solar Heating

Slide 18

Solutions: Woman in India Uses a Solar Cooker

Slide 19

We Can Use Solar Cells to Produce Electricity (1) Photovoltaic (PV) cells (sun based cells) Convert sunlight based vitality to electric vitality Design of sun powered cells Benefits of utilizing sun oriented cells Solar-cell control plants Near Tucson, AZ (U.S.) 2007: Portugal

Slide 20

Solutions: Solar Cells Can Provide Electricity Using Solar-Cell Roof Shingles

Slide 21

The Solar Power Industry Is Expanding Rapidly Solar cells: 0.2% of the world's power 2040: could sun powered cells deliver 16%? Nanosolar: California (U.S.) Germany: tremendous interest in sunlight based cell innovation General Electric: entered the sun powered cell advertise

Slide 22

Using Wind to Produce Electricity Is an Important Step toward Sustainability (1) Wind: roundabout type of sun oriented vitality Captured by turbines Converted into electrical vitality Second quickest developing wellspring of vitality What is the worldwide potential for wind vitality? Twist ranches: ashore and seaward

Slide 23

Using Wind to Produce Electricity Is an Important Step toward Sustainability (2) "Saudi Arabia of wind power" North Dakota South Dakota Kansas Texas How much power is conceivable with twist cultivates in those states?

Slide 24

Solutions: Wind Turbine and Wind Farms on Land and Offshore

Slide 25

Producing Electricity from Wind Energy Is a Rapidly Growing Global Industry Countries with the most elevated aggregate introduced wind control limit Germany United States Spain India Denmark Installation is expanding in a few different nations

Slide 26

Wind Energy Is Booming yet at the same time Faces Challenges Advantages of wind vitality Drawbacks Windy territories might be inadequately populated Winds fade away; require move down vitality Storage of wind vitality Kills transient feathered creatures "Not in my patio"

Slide 27

We Can Convert Plants and Plant Wastes to Liquid Biofuels (1) Liquid biofuels Biodiesel Ethanol Biggest makers of biofuel Brazil The United States The European Union China

Slide 28

We Can Convert Plants and Plant Wastes to Liquid Biofuels (3) Studies caution of issues: Decrease biodiversity Increase soil corrupting, disintegration, and supplement draining Push agriculturists off their property Raise sustenance costs

Slide 29

Case Study: Is Ethanol the Answer? (1) Ethanol changed over to gasohol Brazil: "Saudi Arabia of sugarcane" Saved $50 billion in oil import costs since the 1970s United States: ethanol from corn Reduce the requirement for oil imports? Moderate an Earth-wide temperature boost? Lessen air contamination?

Slide 30

Case Study: Is Ethanol the Answer? (2) Cellulosic ethanol : contrasting option to corn ethanol Sources Switchgrass Crop deposits Municipal squanders Advantages Disadvantages

Slide 31

Natural Capital: Rapidly Growing Switchgrass in Kansas, U.S.

Slide 32

16-9 How Can We Make a Transition to a More Sustainable Energy Future? Idea 16-9 We can make a move to a more reasonable future on the off chance that we significantly enhance vitality productivity, utilize a blend of renewable vitality assets, and incorporate natural expenses in the market costs of all vitality assets.

Slide 33

Choosing Energy Paths (2) General decisions about conceivable vitality ways Gradual move to littler, decentralized micropower frameworks Transition to a different blend of locally accessible renewable vitality assets Improved vitality proficiency How? Fossil powers will even now be utilized as a part of substantial sums Why?
