According to developers, Wales could move closer to its net zero goal by 2050 with the help of a new onshore wind farm.
However, some locals in Bridgend county referred to the Y Bryn plan as a "blight on the landscape" between Port Talbot and Maesteg.
Instead of the original 26 turbines, the 2021 plan now calls for 18 turbines that can reach heights of 250 meters (820 feet).
The Welsh government has committed to reducing carbon emissions and has set a goal of having net zero emissions by the year 2050. .
Among the tallest in the UK, the proposed turbines. The Tower in Swansea, which rises 107 meters (351 feet) above ground, is the tallest structure in Wales.
The plans have now been re-released for public comment, but local opposition groups expressed concern over the size and quantity of the proposed wind turbines.
"My daughter is fifth generation here," said politician Phil Morgan.
"I spend a lot of time walking and foraging in this area, and it would be unfortunate to see it essentially completely cleared of trees and dug up for these foolish projects, these white elephants. ".
The neighborhood is already contributing to the net zero goal, according to Rhodri Williams, a member of the neighborhood residents' action group.
We have more wind farms in this area than we should," he said.
"They ought to concentrate on offshore because that is the region with the most potential and offshore turbines can generate twice as much energy as onshore turbines. .
"This is a temporary solution, and we are being used as a storage facility for the energy requirements of our neighbors. ".
Another local, Delyth Keating, expressed concern about how the turbines would affect the region's expanding tourism sector.
She said, "They come from all over because we are a world mountain bike area.
People do come from other places and stay here. People will simply stop coming here and go elsewhere if we don't have access to the mountain, which we will be denied access to during construction, which will hurt local businesses. ".
For the developer, Coriolis Energy, however, Sara Powell stated: "Onshore windfarms have such a significant role to play in ensuring we reach our targets of net zero that we can't ignore it.
"We have very lofty goals, and the demand for electricity will double over the next few years, so we must deal with this. ".
The developer also claimed that by creating employment opportunities, the wind farm would help the neighborhood.
It also has a deal with a number of neighborhood organizations, which it claimed would help deliver millions of pounds in contributions to neighboring communities.
Awel Aman Tawe (AAT), one of these, is a community energy nonprofit that has built and runs two community-owned wind turbines in Pontardawe, in the Swansea Valley.
In order to develop our own energy security, which requires Wales to produce its own electricity, sites like Y Bryn are "vital for us to develop our own energy security," according to the site's manager Daniel McCallum.
Residents of the village of Bryn who oppose the development claim that even though they are aware of the need for renewable energy sources and have heard the argument in favor of green energy, they are still concerned about the local environment and wildlife.
Dianne Thomas, whose bungalow looks out over the area, questioned the need for wind farms in the face of available alternatives.
"Why not put them out into the sea, on the Swansea barrage? Why not put them in a small village where we are going to see them, and hear them, and I believe could have a tremendous impact on our mental health, which is most important. " .
A full planning application might be submitted before the end of the year, according to the developer, after the required consultation is finished.
According to a Welsh government spokesperson, as we transition to a net zero energy system, we will need a variety of technologies at various scales to meet our future electricity needs.
"Both onshore and offshore wind have a clear place in electricity generation and are affordable options. ".
The spokesperson declared that Wales should be "at the forefront of marine renewable energy."
