So far as feedstocks for the production of biofuels go, kelp is a highly promising one on many fronts, and a new technology promises to boost its credentials even further by maximizing its exposure to both sunlight and nutrients.

Summary
Humanity s most pressing need is to learn how to live within our planet s boundaries - something that likely means doing without economic growth. How, then, can we create a non-growth society that is both just and equitable? I attempt to address this question by looking at an aspect of sustainability (and equity) that is not often discussed: the growth of
hierarchy. As societies consume more energy, they tend to become more hierarchical. At the same time, the growth of hierarchy also seems to be a key driver of income/resource inequality. In this essay, I review the evidence for the joint relation between energy, hierarchy and inequality. I then speculate about what it implies for achieving a sustainable and equitable future.

Introduction
Freshwater is essential for people around the world. However, with the scarcity of freshwater that we are currently encountering, desalination processes need to be improved to efficiently generate clean and safe water. A major issue with desalination systems is that they are very energy-intensive and release harmful emissions into the environment when using fossil fuels. Switching to using renewable sources such as solar energy for desalination systems gives a more environmentally friendly approach to desalination and helps to combat water scarcity.
Advancements in solar energy desalination processes, including electrodialysis and reverse osmosis, will be looked at in this paper. Solar energy has a large potential as a renewable desalination energy source because of its abundance on Earth. Furthermore, advances in solar-wind hybrid desalination systems will be looked at, that demonstrate high efficiency and low carbon emissions as well.
