I got sick of having a disaster of a lawn. Over a decade ago I had vowed to hang up my hoses and not waste money on grass, but something had to be done. I decided that drought-resistant “Celebration” hybrid Bermuda sod was what we needed.
At the end of summer, I killed all the weeds and grass in our front and back yards. A few weeks later I had a giant tractor trailer deliver 11 pallets of sod. It was pouring down rain when the driver arrived. In his efforts to place mulch in our backyard his forklift quickly got mired in the mud at the end of our driveway. For two hours we struggled to get enough traction to free his forklift, only succeeding when my neighbor Chris arrived to help steer as we pulled.
The damage to the back yard had been done, though. A 6,000 pound forklift cut deep ruts in our muddy yard and those ruts had to be repaired before the sod could be put down.
It took back-breaking, Herculean effort by myself, Kelly, and Travis to repair the yard and get the sod put down while it was still alive. I personally pushed myself past the point of exhaustion many nights. I was a wreck. Surprised I didn’t have a heart attack, actually.
It was a stupid, stupid amount of work. But. We. Got. It. Done!
And it looked incredible! For once we had a strong turf grass that didn’t mind the sun or the shade! It’s been perfect.
With the first freeze, the sod has gone dormant and some weeds have appeared but overall it will look fantastic in the spring when it greens up. I won’t have to do much with it to maintain it, either. So far it’s been a great investment in our home.
We should never have called it Earth. Three quarters of the planet’s surface is saltwater, and most of it does not lap at tranquil beaches for our amusement. The ocean is deep; things are lost at sea. Sometimes we throw them there: messages in bottles, the bodies of mutinous sailors, plastic bags of plastic debris. Our sewage.
Sometimes the things we lose slip unnoticed down the sides of passing ships. We expect never to see lost objects again, but every so often they are carried by shifting currents and swirling eddies to wash ashore on distant beaches. We are reminded that things, once submerged, have a habit of returning.
I am not afraid of the ocean, although I should be. On hot summer weekends I take my son to the beach. He toddles toward the water, laughs at the lazy waves splashing his fat baby legs. I follow behind, turn him back when the water reaches his naked belly. He is too young to know the sea gets deeper, that eventually it rises above your head and you must swim so as not to drown. I am prepared for nightmares as he grows and learns about the vastness of the ocean and the monsters real and imagined that swim there. He will soon know that evil things lurk in the deep.
Los Angeles Power and Water officials have struck a deal on the largest and cheapest solar + battery-storage project in the world, at prices that leave fossil fuels in the dust and may relegate nuclear power to the dustbin.Later this month the LA Board of Water and Power Commissioners is expected to approve a 25-year contract that will serve 7 percent of the city’s electricity demand at 1.997¢/kwh for solar energy and 1.3¢ for power from batteries.
“This is the lowest solar-photovoltaic price in the United States,” said James Barner, the agency’s manager for strategic initiatives, “and it is the largest and lowest-cost solar and high-capacity battery-storage project in the U.S. and we believe in the world today. So this is, I believe, truly revolutionary in the industry.”
A remarkable thing happened in the US in April. For the first time ever, renewable electricity generation beat out coal-fired electricity generation on a national level, according to the Energy Information Agency (EIA). While renewable energy—including hydro, wind, solar, geothermal, and biomass—constituted 23 percent of the nation’s power supply, coal-fired electricity only contributed 20 percent of our power supply.
Last month was the hottest June ever recorded, the EU‘s satellite agency has announced.Data provided by the Copernicus Climate Change Service (C3S), implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the EU, showed that the global average temperature for June 2019 was the highest on record for the month.
Ten feet before us, a sewer pipe made out of limestone spews yellow-brownish insults into the reef ecosystem. The pipe’s mouth is barely visible through the cluster of baitfish and foragers, a silver mass of twitch and glide binging on nutrients long processed and evacuated by Broward County taxpayers. A goliath grouper bullies its way through and enters the pipe to feed. I’m told to watch out for fishing lines—an entanglement hazard for the sub’s thrusters. The Hollywood outfall pipe serves as a popular fishing spot, toilet to table.
It is difficult to exaggerate just what a sea change has taken place in the discussion of renewable energy in recent years.
Oldsters like me remember when the idea that (unsubsidized) renewable energy would be able to compete directly with fossil fuels was downright utopian. As late as the early 2000s, people were debating whether it would happen this century, or at all.
But the extraordinary progress of renewables in the past two decades has moved that hoped-for future closer and closer. And now, unbelievably, it is right on our doorstep.
It’s one thing for advocates or energy analysts to say that, of course. It’s something else to hear it coming out of the mouths of energy executives. But these days, residents of the C-suite are discussing renewable energy in terms that would have made hippies blush a decade ago.
Teenagers like to take long showers. They can easily spend 20 minutes in there, idling away their time as well as the family’s hot water. I’d done a few rounds of knocking on the bathroom door. I’d even taped photos of baby Arctic seals on the door to remind the kids of the consequences. Didn’t seem to get the point across.
When one night came where one of the kids drained the hot water from our tank I knew desperate measures were needed. I threatened to switch out the nice Delta showerhead with a miserly spray one, guaranteed to save water at the price of a miserable shower experience. Certainly that would get the point across but I knew I’d soon have to swap it out. You know, the Geneva Convention and all.
I began to ponder how a proper geek might solve the problem. I am a Site Reliability Engineer in my day job and I love gathering metrics on the computers I wrangle. What if there were a way to track my kids’ use of water? Wouldn’t it be great to show them how much water their showers actually use? I began to dream up a product I could create that would do just that but then some clever Googling showed me one was already out there: the Water Hawk. Continue reading →
China’s refusal to accept American recycling could lead to a drastic change in consumer habits. Perhaps we will finally have a discussion about our throwaway society.
For decades, we were sending the bulk of our recycling to China—tons and tons of it, sent over on ships to be made into goods such as shoes and bags and new plastic products. But last year, the country restricted imports of certain recyclables, including mixed paper—magazines, office paper, junk mail—and most plastics. Waste-management companies across the country are telling towns, cities, and counties that there is no longer a market for their recycling. These municipalities have two choices: pay much higher rates to get rid of recycling, or throw it all away.
A good analysis on which mode of transportation is the greenest.
One question we’ve fielded lately with the release of our US airline efficiency ranking is how the fuel efficiency, and therefore carbon intensity, of aircraft compare to other modes of transportation. Vehicles meet a variety of transport needs, in terms of what is transported (people vs. goods), distance traveled (short intercity trips vs. transoceanic transport), and speed (12 mph on a bike vs. Mach 0.85 in a long-haul aircraft). Typically, travelers choose between different transport modes based upon a variety of criteria—cost, speed, comfort, even safety—with carbon footprint generally only a secondary consideration. But, for those relative few who would consider planning a trip with carbon dioxide emissions in mind, here are some preliminary thoughts.
