Tesla: Inventor of the Modern

The following is an excerpt from Tesla, Inventor of the Modern, a new book by Dick Munson published in May 2018.

Nikola Tesla gave us the electric motor, long-distance electricity transmission, radio, robots, and remote control — the very foundations of our modern economy. Perhaps less well known is that he also was a clean-energy pioneer, and he remains an inspiration to today’s solar and battery entrepreneurs, including Elon Musk, who views him as a hero and contributed $1 million to help restore Tesla’s laboratory on Long Island.

Tesla marked his clean-energy leadership with a 1900 article in The Century — then the nation’s largest-circulation periodical. Published 118 years ago, “The Problem of Increasing Human Energy, with Special References to the Harnessing of the Sun’s Energy” was one of the earliest, detailed looks at capturing power from the sun and wind.

At his core, Tesla appreciated efficiency and hated energy waste, complaining that we “do not utilize more than 2 percent of coal’s energy” to make electricity. “The man who should stop this senseless waste would be a great benefactor of humanity,” he declared. Read More »

The latest trends in renewable-energy tech, markets, and policy

By Energy Dialogues

Renewable energy, and its role in energy future, is an intense topic that spans across all corners of the energy spectrum. For example, our recent Mexican Energy Series featured a lively discussion of whether Mexico is on course for the 2024 target of 35% renewable energy, and what this pledge means for the country. Each year, as new corporations, municipalities, and countries make bold and vocal commitments to offsetting energy consumption, and to pursuing clean energy resources at a higher level, the conversation intensifies.

For an insider perspective about the current state of renewable energy, we called upon Lenae Shirley, Senior Director, Technology Innovation and Market Adoption for Environmental Defense Fund (EDF). Lenae is working at the nexus of technology, markets and policy, leading efforts with EDF’s demonstration partners to prove the impact of clean technology innovations. As a result of these initiatives, Lenae identifies trends and market opportunities to accelerate the transformation of the electricity sector, with data-driven decisions that push forward market adoption for renewable methods. Here is our conversation. Read More »

How location-based prices and utility rewards could help California’s electric grid

By Larissa Koehler, Jamie Fine

Distributed energy resources, from rooftop solar panels to smart well-weatherized homes and timed electric vehicle charging, are vital pieces of the clean energy puzzle. Coordinating how and where to encourage them in a way that benefits the electric grid, the environment, and Californians can be complicated. In its’ Integrated Distributed Energy Resource proceeding, the California Public Utilities Commission (Commission) recently asked stakeholders [PDF] to “consider how existing programs, incentives, and tariffs can be coordinated to maximize the locational benefits and minimize the costs of distributed energy resources.”

This key step forward in the proceeding is potentially a big deal. Why? Rocky Mountain Institute’s report puts it this way [PDF]:

“More granular pricing, capable of reflecting marginal costs and benefits more accurately than today’s rates do, will provide better incentives to direct distributed resource investments, regardless of whether investments in and management of [distributed energy resources] are undertaken by customers, by utilities, or by third-party service providers.”

By reflecting both costs and benefits in retail prices that electricity customers pay, California can modernize the grid while spurring the efficient and fair build out of distributed clean energy resources. This can help the state substitute traditional and inflexible polluting resources [PDF] with a variety of more nimble distributed energy resources where the grid can handle them. What’s more, distributed energy resources can lead to cleaner air in areas traditionally burdened by higher levels of harmful air pollution. They can achieve all this while bolstering the electric grid and protecting the health of the environment and of Californians. Read More »

The most important thing California can do with its clean energy could be to share it

Not often is running the electric grid as simple as applying lessons from childhood. Right now it is ─ California is learning to share with its neighbors. A bill currently in front of the Legislature from California Assemblymember Chris Holden, AB 813, aims to build a better trading platform to share California’s extra solar power with nearby states like Oregon, Washington, and Nevada, which would then share their extra wind, solar, and hydropower resources with California.

It is like the lunch table you sat around as a kid – one where you can trade that banana pudding that overflows at your house for one of your neighbor’s chocolate chip cookies. It’s a delicious deal, where everybody wins.

That deal just got better. Holden’s office yesterday released new language which represents an important, positive step in the process of creating a regional electric grid for the West. This includes key requirements and protections to ensure a regional grid lowers harmful greenhouse gas emissions and supports California’s climate and energy goals – helping the state and its neighbors to move towards a low-carbon future.

Rural communities need internet access, and rural electric co-ops are providing it

When I stop for a quick bite back home in rural North Carolina, I know the restaurant crowd is not always an indication of how great the food is. Often people are there for the free internet connectivity because access is very limited in the community.

The digital divide between those who have internet at home and those who do not occurs in both rural and urban areas. It is markedly apparent in rural communities, where nearly 40 percent of residents lack access to broadband, compared to 4 percent in cities.

As a result of the digital divide, rural communities are suffering, yet are coping in innovative ways with the help of strong leadership from rural electric cooperatives. More than 900 member-owned, non-profit rural electric co-ops today represent more than 42 million people in 47 states.

Rural electric co-ops are more than just poles and wires; they are economic drivers for the communities they serve. They are in the business of not only providing energy, but also social and economic benefits. Read More »

A roadmap for a clean, modern grid – The 6 areas that should guide our efforts

Everyone has a role to play in fighting climate change. Farmers can use new methods to rotate their crops that keep more carbon safely in the ground. Consumers can act with their wallets – buying goods and services that produce less carbon than competitors. Our elected officials, of course, have a lot of influence in setting the narrative and enabling support for climate progress.

But around the country, in municipal buildings, state offices, and corporate headquarters, separate groups of people are busy designing and implementing changes that could have the biggest impact of all: a better, smarter, more modern grid.

Improving our electricity system could be the single largest climate fighting opportunity we have. But it’s not as simple as just putting solar panels on rooftops. Our grid was built over a century ago by different companies, cities, and co-ops. Pieces of it are owned and run by a dizzying web of stakeholders. Even if we could snap our fingers and spur all of these pieces to action, each player would manifest different versions of a “modern grid.”

Environmental Defense Fund (EDF) thus released a guide titled, “Grid Modernization: The foundation for climate change progress” [PDF], which outlines the six key categories that make up a sustainable grid modernization strategy. All of them are connected, either physically or digitally, or by legislation, regulation, or management. Most importantly, they’re connected by efficiency: If each of them is executed well, the whole grid modernization process will yield the best, most reliable, most affordable, and cleanest electricity system.
