Tesla’s Powerwall Puts Huge Crack in Carbon-Based Energy Dominance

“I think we should collectively try to do this, and not win the Darwin Award.” — Elon Musk

This week, with much fanfare, Elon Musk’s Tesla launched a new venture — Tesla Energy.

It’s a move that propels Telsa into direct competition with giant fossil energy companies. One that promises to disrupt the global power markets and to free a vast number of consumers now held captive to home and transport based fossil fuel energy use. An offering that provides a glimmer of hope for an escape path out of our current nightmare of an ever-heating global climate.

(Elon Musk presents Powerwall together with a nice, succinct summary of our current carbon emissions crisis.)

Freeing the Fossil Fuel Energy Slaves

As with Tesla’s earlier electric vehicle offerings, its new energy product seems humble. But don’t let looks fool you, because this little beast packs one hell of a wallop. Dubbed Powerwall, the offering is a scalable battery storage system. In its home energy incarnation, it comes in trim dimensions — 7 inches thick in a 4×3 foot stack. For homeowners, it provides two options — 7 kwh of storage for 3,000 dollars or 10 kwh of storage for 3,500 dollars. A low-cost, high quality offering that will allow individual and family solar users to say to hell with the grid, contentious fossil fuel interest muddied utility politics, and any coal or gas fired powerplants if they so choose.

Both stacks provide more than enough storage to get the average homeowner through a night’s electricity usage, with the 10 kwh stack providing a bit more flex. The stacks also provide back-up for grid tied homes during power outages. It’s enough flexible storage to run virtually any home on solar + battery power alone. That’s the real, revolutionary aspect of this system — cheaply and seamlessly providing homeowners the means to run on all-renewable power, all the time.

When combined with the ever-less-expensive and more reliable home solar arrays now becoming more readily available, this combination now poses not only a threat to fossil fuel based grid and vehicular energy — it represents a superior option to energy users on practically every level. Energy costs go down, reliability during storms goes up, and environmental impacts — carbon emissions, water use, and energy use based air pollution — go down or are virtually eliminated.

Massive New Market for Tesla

From a business standpoint, this is a huge breakthrough for Tesla. Previously, the company competed in a market rife with rivals. Still, it managed to succeed and even dominate by offering some of the highest quality vehicles in the world. Vehicles that pushed sustainability for the automotive industry toward new frontiers and provided a threat to both internal combustion and fuel cell based autos all in one go. But now, Tesla enters the power storage market with practically no comparable rivals. Its Powerwall is both the lowest cost and the highest quality storage solution available and it breaks new ground in an established, multi-billion dollar home energy market.

In an article today in Scientific American Karl Brauer, a senior analyst for Kelley Blue Book, noted:

“If Tesla can produce a cost-effective home energy storage system, it could prove far more valuable, and profitable, than anything the company is doing with automobiles.”

Intermittency Constraints Reduced, Hitting Renewable Economies of Scale

Tesla’s Powerwall shatters the myth that renewable energy can’t effectively function due to its intermittency. That renewables require high price storage options to provide energy 24/7. Tesla’s offering enables 24/7 renewable power at low cost. The option it provides is scalable to utility level, and its modular construction leverages renewable energy’s distributed power advantages. It’s a complete game changer that should have fossil fuel execs quaking in their boots and those of us concerned about climate catastrophe feeling a bit more optimistic.

Recent statements by Musk indicate that the new energy industry wildcard is ready to go all out for both new homeowner and utility customers. The company mentions one major utility that is already interested in a 250 megawatt battery storage buy. And Tesla plans to work with partner Solar City in developing comprehensive home solar + storage options.

Finally, the synergy between the Powerwall and the electric vehicle battery should not be missed. Large scale production of Powerwall will serve to leverage economies of scale and drive down battery costs both across the energy storage and electric vehicle sectors. Tesla is planning for this through the construction of not just one but multiple gigafactories — assembly plants capable of producing hundreds of thousands of battery packs each (See Tesla Gigafactory May be First of Many). And, even more impressive, Tesla plans to provide its patents to other players looking to rapidly scale battery production. It’s a nightmare scenario for fossil fuel companies, but a much more hopeful one for the rest of us. A bit of much-needed good news in an otherwise grim present.
