How to Cut U.S. EmissionsFaster? Do What These
Countries Are Doing.BY BRAD PLUMER AND BLACKI MIGLIOZZI FEB. 13, 2019
The United States is reducing its greenhouse gas emissions far too slowly to help avert the worst effects of global warming. But what would happen if the country adopted seven of the most ambitious climate policies already in place around the world?

IMPROVE WHERE WE LIVE AND WORK When we build better buildings, we are putting new skills and newly-skilled workers to work, and building owners and residents save money in the long run. Building technologies are a place where the B.C. technology sector excels. We have been a proving ground for building energy management systems and low carbon building materials, and CleanBC will help us move forward to a future where buildings produce no emissions at all – starting with the following actions. Better buildings ! Make every building more efficient by improving the BC Building Code and increasing efficiency standards – until every new building is “net-zero energy ready” by the year 2032 Support for better buildings and home retrofits 1! "Incentives to make heat pumps more affordable and homes more energy-efficient 2! "Upgrade B.C.’s stock of 51,000 public housing units to make these homes less polluting, more energy-efficient,
and more affordable 3! "Make residential natural gas consumption cleaner by putting in place a minimum requirement of 15% to come
from renewable gas Support for communities ! Help remote communities reduce dependence on diesel! Support public infrastructure efficiency upgrades and fuel switching to biofuels with the CleanBC Communities Fund Together, these initiatives to improve where we live and work will bring down our carbon pollution by 2.0 Mt by 2030.

Although solar hot-water systems usually just heat domestic hot water, they can also heat a house by radiant (in-floor-piping) heating.

What can we do to stop the heat passing through the glass by conduction?A vacuum will do the trick but how do we stop the force of air pressure squashing the two pieces of glass so they touch?
Pilkington Spacia™
These windows have almost no thermal conduction but must still be coated to reduce radiation losses.

It is within production tolerances to have a maximum of two missing or misplaced micro- spacers within a 540 mm × 540 mm square. However, microspacers cannot be missing from the outer most row.
The microspacer grid ensures that the two glass panes are kept a fixed distance apart. When looking through the window from 2-3m away, they are imperceptible.
Could we use this on flat-panel collectors?
Now a little about heating houses.

1 Very good windows: triple-glazed windows with two of the six glass surfaces coated to reflect heat.

3 A house that is built today can last for 100 years, but the street would last much longer.
4 The Ventilation SystemHeat recovery ventilator.
5 Inner Returns (Internal gains) 100 Watt heat energy per person: A 15 m2 room in the house with huge windows, (when it is 12 °C outside), has a maximum heating need of around 400 Watt. On the coldest days of the year, two people and four candles (80W ea) alone will stoke the room.

Many on the Sunshine Coast heat their houses with baseboard electric heaters.
Advantages:- simple- cheap (no ducts)- no air loss via chimney.- easy to control.
Disadvantages:- fire danger with full-length curtains.- doesn’t make full use of the high quality of the electric energy.
3 units of heat => 1 unit of electricity => 1 unit of heat.
Closer to home...
56Wednesday, February 13, 2019
Advantage:3 units of heat => 1 unit of electricity => 3 units of heat.
A heat pump, uses an electric motor to force a fluid through a cycle of heating and cooling.
By properly positioning the hot and cold radiators, it can “pump” heat from a cool area (i.e., outside) to a warmer area (i.e., inside). (Seems backwards?)
Disadvantages:- Complexity.- Expense.- Service risk.
57Wednesday, February 13, 2019
58Wednesday, February 13, 2019
An air--to-air heat pump looks a bit like an air conditioner, in two parts (connected by tubing).
They can usually also be run “backwards” to cool in summer.
Heat pumps can be either air-source or “ground” source.
59Wednesday, February 13, 2019
They work well where the air doesn’t get too cold in Winter.
60Wednesday, February 13, 2019
Where winter air is too cold, a “ground source” can be a field or a well,
or even a lake.
61Wednesday, February 13, 2019
But it is more complicated and if it breaks down or you get a leak, you have a problem

- inefficient, (25% at best, in cities, closer to 6%),
- only work by stealing O2 and changing it to CO2 -> Climate!
- complicated (require constant service)
- polluting (smog and diesel soot kill thousands annually)
- Smaller,
- Lighter
- Lots of horsepower!
- But most of all, because they use a cheap, storable energy source.
Gasoline and diesel engines are:
Well, compared to steam engines, they are
Why do we tolerate them?
70Wednesday, February 13, 2019
Gasoline and diesel are such popular fuels because:
They’re “cheap” and you can store a lot of energy in a simple tank.
A 2 minute refill allows you to drive your car 300 miles.
A barrel of oil costs $50 but contains the same energy as would be put out by a man working hard (100Watts), 24/7 for 2 years.
Burning 1 US gallon (3.8 L, ~3kg) has same energy as exploding ~300 kg of TNT.
A gas pump pumping at half-a-litre/sec is “charging” you car at the rate of 17 MegaWatts!
About 17,000x more energy/second as used by your house (1kiloWatts).
The fastest electric fast chargers in Europe carry 175kW, 100x slower.
Imagine pushing your car at 100km/hr for 15km for $1.00!
71Wednesday, February 13, 2019
That sounds pretty bad, but we need to check the details.We aren’t really interested in energy transfer, but in the transfer of the ability to travel a certain distance. Because most gas cars are heavy and gas engines are inefficient, they burn gas at the rate of ~100kW @ 40mph.
A modern, efficient Tesla with a100kWh battery can go 335 miles (536km) on one charge.At an average speed of 40mph, this will take 8.4 hours and you will have used power at the rate of ~12kW or about 16 horsepower.
http://www.ocean.washington.edu/courses/envir215/energynumbers.pdf
i.e., the Tesla is about 8.3x more efficient.So charging isn’t 100x slower, only 12x slower.
72Wednesday, February 13, 2019
Still at 150kW, we are still talking about 3x the maximum power available from a 220v, 200A Canadian residential service.
Could we go faster?
Sure, just have a big battery at the charge station.

The key to making successful electric cars is low weight. Use carbon-fibre-reinforced plastic or aluminum alloys.
Making cars lighter is MORE important than making better batteries.

The main worry with electric cars: “range anxiety.”Solutions:- smart cars can keep track of nearby charging stations- batteries slowly improving- cars getting lighter as more carbon fibre used- self-driving cars that “talk” to each other can reduce air drag- “real” limits may change car use patterns: Car-sharing.

3. Open-ended tax-relief for electric vehicles. 4. Municipal-provincial cooperation to deliver the perks. 5. Cross-party consensus to maintain support. 6. Smart-charging infrastructure and distribution network needed to overcome grid stresses.

Across the US on one tank of Bio-diesel!
What about biofuels?(hydrocarbons derived from crops)
(one person, big tank!)
If the sunlight that grew the corn were instead collected by PVcells, the electric energy produced could drive a battery/electric car 20-50x farther than the biofuel.
The problem is that photosynthesis and the other processes used to make the biodiesel are not energy efficient.
