This activity is designed to improve sentence accuracy and complexity. Most students can produce the key content words in a sentence. However, they have difficulty with accuracy because the functional words are difficult or can seem unimportant. This activity will help learners eliminate problems with these functional words by giving them immediate feedback on the mistakes they are making. It will also help students develop their use of more natural, varied and complex sentence structures.
TIP: Say the sentence out loud. Notice the types of mistake you make often. Focus on those types of errors. (singular/plural, subject-verb agreement, article use, prepositions, gerunds and infinitives, noun clauses, adjective clauses, word order, and word forms.)
Esta actividad está diseñada para mejorar la precisión y complejidad de las oraciones. La mayoría de los estudiantes pueden producir las palabras clave del contenido en una oración. Sin embargo, tienen dificultades con la precisión porque las palabras funcionales son difíciles o pueden parecer poco importantes. Esta actividad ayudará a los alumnos a eliminar problemas con estas palabras funcionales al brindarles retroalimentación inmediata sobre los errores que están cometiendo. También ayudará a los estudiantes a desarrollar su uso de estructuras de oraciones más naturales, variadas y complejas.
CONSEJO: Diga la oración en voz alta. Observe los tipos de errores que comete con frecuencia. Concéntrese en ese tipo de errores. (singular / plural, concordancia entre sujeto y verbo, uso del artículo, preposiciones, gerundios e infinitivos, cláusulas sustantivas, cláusulas adjetivas, orden de las palabras y formas de las palabras).

The state of Vermont has one of the greenest grids in the US. Two thirds of their electricity comes from renewable energy sources,
like solar, wind, or hydroelectric plants. The current goal is to be at 75% by 2032. Which is why it was pretty surprising when a
new solar project here was denied.
This area doesn’t have a lot of people, but it does have plenty of potential for renewable energy. The power plants here, in addition to a regular power supply from Canada, already put about 450 megawatts of electricity onto the grid — and by grid, I mean these power lines — but the grid’s capacity is around… 450 megawatts. So the grid just wouldn’t be able to handle any more power generated here.
If we want a greener future in the US, we’ll need to build more renewable energy plants. But to actually use that electricity, we’ll also need to build more of these.
This is a map of where everyone in the continental US lives; the density of each county. Here’s New York City, LA, Chicago. And here’s where every big power plant is currently. Appropriately, they tend to be where the people are. In Washington, DC, where I live, we get nearly all our electricity from surrounding states’ power plants— mostly nuclear and natural gas. Electricity goes from the power plant, through big high-voltage transmission lines, to a substation, where the electricity is dispersed onto smaller, lower-powered distribution lines, that send it into my house.
So, back to the map. If we’re going to replace all these polluting energy plants, we can’t just build a wind turbine in their place. They need to be where it's, you know, windy. This is a model, created by Princeton, mapping out possible places in the continental US where wind and solar projects could, in theory, be built. Aside from some offshore wind farms, it's mostly in the middle of the US. Another study found that these states have most of the wind and solar potential, yet the people living there would only make up 30% of the electricity demand.
In a decarbonized future, we’re going to need to get electricity from here to here. And, we’re going to move a lot of it. That’s where high-voltage transmission lines come in.
ROB GRAMLICH: I think the infrastructure is the most important thing. It doesn't get a lot of attention but it really is the key.
This is where the US currently has high-voltage transmission lines. The Princeton model shows this is where new lines will need to be built if the US uses all renewable energy by 2050. But it’s not a simple process.
Every wire in your house has plastic over it, because if two electrical lines get too close... But high-voltage power lines are the bare active wire. No plastic. They’re insulated by the air. Basically, if they’re kept far enough apart from each other, it’s safe. But they also have to be kept far away from everything - trees included. This is actually how some of the California wildfires were started: Trees coming in contact with the super-big high-voltage transmission lines.
And those are what we’ll need more of, as we lengthen the distance from energy source to energy need. We’ll also need to make many current ones even bigger. Because bigger means more power. Physically, the cables are thicker — the bigger the cable, the more power can run through them. And because they’re bigger, they have to be really far apart for insulation, and built higher up. It makes them kind of a pain to build -- partly because of how large they are, but also how much private land they have to cross.
GRAMLICH: Very often, the developer can get 99% of the landowners to agree, but then there's that last 1%, and that can take forever, and can crater the whole thing.
So experts say we should start building now, even before we build the plants.
GRAMLICH: You can do a generation project in a year. The transmission, three, if you're lucky, but it can go over ten. We don't want to do this in a reactive mode, where we build a lot of stranded generation. We want to proactively build the transmission to where we know the resources are. And the thing about wind and solar resources is, we know where they are.
Just making greener electricity isn’t enough. We have to be able to move it.
GRAMLICH: Transmission is important for the clean energy future. We're just not going to decarbonize without it.
