The U.S. Energy Information Administration recently published a special short profile on New York's renewable energy leadership and split. What I found particularly interesting in the piece, though, was the variation in renewable energy splits in the different top states.
About 57.6 percent of electricity generated in Iowa came from renewable energy sources. No other state had more than 45 percent.
Is the act of mining for cryptocurrency damaging to the environment? We asked Joseph Raczynski, our resident futurist, to assess this emerging landscape.
This updated edition of the industry standard reference on power system frequency control provides practical, systematic and flexible algorithms for regulating load frequency, offering new solutions to the technical challenges introduced by the escalating role of distributed generation and renewable energy sources in smart electric grids. The author emphasizes the physical constraints and practical engineering issues related to frequency in a deregulated environment, while fostering a conceptual understanding of frequency regulation and robust control techniques. The resulting control strategies bridge the gap between advantageous robust controls and traditional power system design, and are supplemented by real-time simulations. The impacts of low inertia and damping effect on system frequency in the presence of increased distributed and renewable penetration are given particular consideration, as the bulk synchronous machines of conventional frequency control are rendered ineffective in emerging grid environments where distributed/variable units with little or no rotating mass become dominant. Frequency stability and control issues relevant to the exciting new field of microgrids are also undertaken in this new edition. As frequency control becomes increasingly significant in the design of ever-more complex power systems, this expert guide ensures engineers are prepared to deploy smart grids with optimal functionality.
The cryptocurrency’s high value comes at a high cost to the planet.
Our bar table is a bestseller year over year. Available in hundreds of hard-to-find size combinations, every space is elevated with the addition of this custom-sized bar or community table. The sturdy, versatile and classic design is a magnet for gathering. -Handmade with reclaimed wood -Offered in our three signature finish colors—Natural, Provincial or Espresso | Shop our other listings for each finish option -Available in three heights: Dining height table, counter height table or bar height table -Simple leg assembly required -Recommended for indoor use only ADD-ON FEATURE DETAILS Power Grommets: Grommets are installed into the tabletop and the power supply cord drops from the underside of the table. The supply cord must be plugged in to power the tabletop outlets. Placement of the grommet on the tabletop is selected when adding to your cart. All grommets are equipped with: -Two (2) AC outlets (125V/12A) -Two (2) USB-A (5V/2A Max), and -One (1) USB-C (5V/2A Max) charging port. Caster Wheels: Our caster wheels feature floor-safe rubber wheels that slide easily, with a sturdy locking feature. Caster wheels do not add height — we modify the legs to maintain your chosen dimension. Seating: To find the approximate space available for seating, subtract 8" from the table length. For example, a 72” table offers 64” of room for seating. For more guidance in understanding dimensions, selecting the right design, finish colors or the right add-ons for your space, send us a message. We're here to help. ABOUT OUR FURNITURE -Fully handmade with reclaimed wood -Every piece is offered in three finish colors — Natural, Provincial or Espresso -Wide range of customizability, including height, length, width and add-on features -Sustainably sourced, built and delivered -Heirloom-quality built to last for generations -Made with environmentally friendly materials -Low maintenance care and upkeep -Lifetime guarantee -Free shipping within Contiguous USA | Flat fee to Canada -Carbon offset shipping on every order -Recommended for indoor use only -Crafted at the speed of human in Phoenix, Arizona Our wood is selected for its health, strength and inherent beauty. We carefully curate planks for every order, rendering each piece truly one-of-a-kind. The nature of reclaimed wood includes nail holes, grain, knots, fade and markings from its origin and life history. Our restorative process is careful to refine rather than disguise these elements. All of our furniture goes through a consistent, cohesive process that both elevates and honors the legacy of old made new. SHIPPING Kase Custom furniture is made-to-order, and current build time is reflected in the announcement bar. Once shipped, transit time is typically 3-8 business days depending on destination location. Our complimentary shipping modalities are either Freight or FedEx Ground, and are determined by accessibility in your area. Please note freight is delivered at the curb-level by appointment and FedEx Ground services as standard for your address. If you need or prefer assistance with your delivery, we offer full service White Glove delivery. This is a premium delivery option for a $250 fee. White Glove includes inside delivery to room of choice, unpacking, placement, assembly, and debris removal. Available for deliveries within the Contiguous USA. Visit etsy.com/listing/1013347095 to add White Glove to your order. If you require special arrangements for delivery, simply send us a message. We regularly accommodate delivery holds for travel, moving, new home or business builds and interior design project needs. NEED FURNITURE NOW? If you’re looking for furniture without the build time, take a look at our READY TO SHIP pieces. This in-stock collection ships within 3-5 business days. ADDITIONAL CUSTOMIZATIONS We can further customize a range of elements on our existing designs beyond the length, height, width, and add-on options on product listings. We invite you to share your request(s) in a message so we can explore together if we’re well-suited to build your vision for you. LARGE ORDERS FOR COMMERCIAL SPACES We regularly build for restaurants, bars, hotels, and event producers. We focus on a seamless experience of furnishing these spaces and offer perks for large or professional orders. Let’s talk! Send us a message to start the conversation. RECLAIMED WOOD CARE Kase Custom furniture is designed to highlight the rustic character, heritage, and natural beauty of reclaimed wood. Proper care for this long-wearing, sustainable material will nourish its timeless appeal for generations to come. -Use a damp lint-free cloth for regular cleaning -Add a drop of natural soap as needed -Promptly dry moisture NOTE: Your furniture never needs detergent, bleach, ammonia, or all-purpose cleaners. Many of these products are harmful to the finish, wood and environment. RETURN POLICY & LIFETIME GUARANTEE Our furniture is made-to-order precisely to your customizations, and as such, orders are final sale. If you're unsure about selecting the perfect dimensions or style for your space, we offer a complimentary design service. Just send us a message!

Our meticulous build process is designed so you never need the warranty, but in the rare instance you do, we have an uncomplicated approach. Simply message us to determine a repair plan.
Are your crypto dreams destroying the planet? Here's everything we know so far.
This book presents innovative techniques and approaches to maintaining dynamic security of modern power systems that have a high penetration of renewable energy sources (RESs). The authors propose a number of frequency control strategies and schemes to address and evade stability problems in system frequency and voltage that can lead to power interruption and power failure/blackout. The book includes case studies aimed at validating the effectiveness of the techniques and strategies presented, and will be a valuable resource for researchers working in electrical power engineering, power system stability, dynamics and control, and microgrids.
