Nearly every country in the world has agreed to cut back on a potent greenhouse gas.

Ravaging crops, drowning goats, and wrecking fishing boats, the Category 4 storm devastated the financial mainstays of an already impoverished people, the Miami Herald reports.

While experts struggle to calculate Matthew’s long-term economic toll, Haitian farmers can see their losses in front of them, in fields littered with rotting fruit and fallen palms. Half the livestock and almost all crops in the nation’s fertile Grand-Anse region were destroyed. Although vegetables can be replanted, it will take years for new trees to bear fruit again. “This was our livelihood,” Marie-Lucienne Duvert told the Herald, of her coconut and breadfuit plantation. “Now it’s all gone, destroyed.”

The farmers, who have yet to receive any relief, are facing threats from famine and contaminated water. Matthew has already caused at least 200 cases of cholera, which could mark the beginning of an outbreak like the one following 2010’s crippling earthquake that claimed 316,000 lives and left 1.5 million homeless.

The death toll from the storm is over 1,000 in the Caribbean, a number that will likely continue to rise as Haitians struggle to find food.

Two senators want the U.S. to start selling war bonds — to fight climate change

Two senators want the U.S. to start selling war bonds — to fight climate change

By on Apr 28, 2016Share

What if we fought climate change with the same commitment we fight wars? The Green Party’s Jill Stein and Al Gore have long argued for a World War II-scale mobilization to fight climate change, and on Wednesday, two senators introduced a bill — the Climate Change Adapt America Bond Act — that’s the most concrete realization of this concept yet.

Sens. Barbara Boxer (D-Calif.) and Dick Durbin (D-Ill.) propose issuing up to $200 million worth of infrastructure bonds to raise funds for climate change adaptation efforts like seawall construction, desalination, and drought resilience programs. The bill would leverage public interest to fend off the climate menace, modeled after the U.S. War Bonds program from World War II.

A bit like “We Can Do It,” no?

Not all observers are pleased with the bill’s focus on adaptation efforts. Margaret Klein Salamon, director of advocacy group The Climate Mobilization, called it “a defeatist strategy — as if war bonds were sold to Americans so they could better adapt to Nazi rule rather than actually attempt to win the war.”

Salamon also pointed to the scale of the proposal, noting that the $200 million figure pales in comparison to the $185 billion worth of war bonds purchased during World War II. Adjusting for inflation, that’s over $2 trillion today.

Two senators want the U.S. to start selling war bonds — to fight climate change

How to Choose an Energy Efficient Water Heater

Conventional water heaters have a 10 to 15-year life expectancy, so sooner or later, the water heater in your basement or utility room is going to stop working, or worse, stop working and start leaking. When that happens, youre likely focused on getting the problem fixed as quickly as possible, and not making a careful decision about what type of water heater you want. It’s best to starting thinking about a new water heater before you actually need one.

If you want to trade up to a more energy-efficient model or a bigger unit, do your homework now, so you can better discuss your options with your plumber when its time for replacement. If you leave the decision to the plumber, he or she might simply replace your existing water heater with a similar model.

Go for Energy Efficiency

Water heating accounts for 18 to 20 percent of the average households energy bill, and is second only to heating and cooling for claiming the biggest chunk of the energy budget. Replacing an old unit with a high-efficiency model will save you money and reduce your home’s overall energy usage.

The savings can really be significant. Thanks to new minimum water heater standards that went into effect last year, even standard models are more efficient than those manufactured in the past. Some models can reduce energy usage by 50% or more. However, those types of savings are only available on heaters that use heat-pump technology. The savings from conventional gas and electric water heaters will only be around 4 percent, according to the Department of Energy. But on a large scale, this shift to new standards will save 2.6 quadrillion BTUs of energy over 30 years and save consumers about $8.7 billion in energy bills. The resulting reduction in CO2 emissions will be like taking 33 million cars off the road for a year.

Read the Label

The easiest way to pick an energy efficient water heater is to read the Energy Guide label that comes with every unit. The label tells you the cost to run a specific unit compared with similar water heaters. If the label carries the Energy Star logo, the water heater meets additional criteria and is more efficient than standard models.

There are a number of considerations that help determine the estimated costs on the label. One of those considerations is the energy factor (EF). This number reflects the efficiency of the heater in converting fuelnatural gas, propane and the likeinto hot water. The EF is expressed as a decimal, so an EF of 1.0 means that 100% of the energy is converted to hot water. Electric water heaters often have a higher EF, but they can be more expensive to operate than gas-powered models. See the table below for more information.

Requirements for Residential Water Heaters

Type of Water Heater
New Minimum EF Requirements
Energy Star EF Requirements
50-Gallon Gas Water Heater
0.60
> 0.67
50-Gallon Electric Water Heater
0.95
> 2.0
Tankless Water Heater
0.82
> 0.90

Know the Hybrid Systems

Hybrid water heaters use electricity and heat pump technology to produce more energy than they consume. That’s why Energy Star products often have an EF of 2.0 and higherthey produce two times the energy that they use in electricity. The heat pump draws heat from the surrounding air and uses it to heat the water in the tank. When the surrounding temperature drops, the unit switches to standard electricity to heat the water.

Heat pump water heaters are very efficientsome models have an EF above 3.0. However, theyre also more expensive. You can expect to pay a 50 to 70% premium for a heat pump water heater.

Tankless water heaters are another option. These units provide on-demand hot water, so no energy is wasted heating water thats not being used. Tankless heaters are sized in gallons per minute (GPM) of hot water they provide. It can be tricky to figure out the right size for your family, so if youre interested in a tankless water heater, discuss your needs with a plumbing professional.

Size Matters

If you are satisfied with the amount of hot water your current water heater provides, there is no need to replace it with a larger model, as prices increase as the tank size grows. But if you do want a larger tank, there are a number of things to consider.

The most important is the First-Hour Rating listed on the Energy Guide label. This is a calculation that tells you the number of gallons of hot water the unit will provide over a set period of time. Its different from the tank capacity, because as you start using the hot water, cold water rushes into the tank that needs to be heated. The First-Hour Rating considers the size of the tank, the efficiency of the unit and even the temperature of the cold water entering the tank. A professional plumber can help you arrive at an accurate size.

Dont wait until a crisis to think about replacing your water heater. Understanding your options now will make the buying process much smoother when its time for a new model.
